Reddit mentions: The best lab tubes

I built this for about $20 (not including the erlenmeyer and the stir bar).

I got the cigar box a while back at a second hand store.

Here's the USB powered PC fan I used:
http://www.amazon.com/Thermaltake-Mobile-Fan-External-Cooling/dp/B00080G0BK/ref=sr_1_2?ie=UTF8&qid=1381376532&sr=8-2&keywords=usb+pc+fan

I chose a usb fan so that I could power it with an android usb phone charger and not screw around with splicing wires.

Here's the magnets I used (just needed one though):
http://www.amazon.com/gp/product/B00B1M37MY/ref=oh_details_o00_s00_i02?ie=UTF8&psc=1

Aside from that it just took a few odd nuts, washers, and a bit of superglue. I had to bore the hole in top of the cigar box because the box turned out to be a bit too thick (sorry Pepin Garcia!) to get enough attraction between the magnet and the stir bar. I think I might have had better luck with stronger magnets or a different stir bar but oh well.

As someone suggested I first glued a washer to the fan so that I could move the magnet around a but to find the sweet spot where it didn't shake too bad then I glued the washer in place.

I used the long bolts/nuts that came with the fan to attach it to the lid (you can see the bolts in the first picture). Between the top of the fan and the lid I had to add washers to keep the fan from rubbing on the cigar box.

That's pretty much it. The fan has a variable speed control but I get a small vortex on the lowest setting, and higher settings throws the bar off the magnet.

Now I just need to wait for my soda preforms to show up so I can start saving a bit more yeast after I use the stir plate!

I got the idea for using the soda preforms from here:

Well you can't really infuse anything into the dry ice because the industrial systems used to produce it use multistage separation and cooling. You might be able to do a "soak", but what you will get is an outer coating of your liquid that is frozen around the dry ice pieces. Then you could throw these into your drinks and watch the fireworks go off. This will almost certainly have the exact same effect as if you had just thrown in dry ice pieces into the drink, since the coating will dissolve into the liquid faster than being attached to the CO2 gas. But if that's what you want I would break up everything into the sizes you want, throw them into a cooler (the dry ice will be your main source of temperature regulation, so make sure it is well insulated), and let it do its thing. Not sure how long these will last, so it would be best to make them within a couple hours of serving time

If what you are going for is to have the sublimating CO2 carry your flavor compounds into the air, you're going to have to go via a different route. A couple modernist restaurants do this type of thing, where they build a center piece and pour their aromatic liquid over it. This massively changes the perceived flavors (and adds a bit of showmanship to the dinner), since a good portion of taste is dependent on associated smells. Here is the Fat Duck doing it.

If you wanted the drink to carry the smoke, rather than a center piece, then you are going to need some custom glassware. Not sure what your budget is, but you could have something designed and made to suit your needs. If that seems a tad too much, I would build something from existing glassware. Take a normal glass and throw one of these short test tubes on the side, or get some plastic tubing and run it spiraling around the outside of the glass (just depends on your style and what you are going for). After that you can fill up the well with dry ice dust, and when you are ready to present pour in some aromatic liquid. You're going to want to make sure nothing comes out while your guests are drinking from their glass, so I would recommend a stopper of some sort that you have heavily perforated or something porous like a piece of sponge that you have cut to the right shape.

Not sure if this answers your question, but I tried to cover all possible bases. Best of luck with your cocktails!

I've got 14 different strains right now by my last count. Just stepped up a frozen Imperial Juice last night and I'm stepping back up a frozen Bell's House yeast as I type this.

I use these but it doesn't seem they're for sale anymore. In any case, any 50ml vial will probably work.

My normal routine is to make a 1.5L starter in a 2L flask and decant off most of the supernatant after the fermentation is complete. I try to swirl in a little just to make sure that the yeast isn't too thick and can actually pour. A semi-thick starter like this, for me, will usually fill 6-8 50ml flasks up to the 25ml mark.

Starter calculators are a wild guess at best in terms of actual cell counts, but if I can suppose that I have close to 30-40b cells per vial I'm usually okay with that amount.

For glycerin, I use a 10% mix total (20% mix into the vial). Usually 1 cup of distilled water and 1/4 cup of glycerin will be plenty for my fills. I'll take this mix and stir it together in my instant pot. I cook the mix for like 3 minutes on high pressure and then release it. I'll take the pot out of the instant pot and let it cool with the lid on.

Once my glycerin is cool and my yeast is decanted I'll fill as many 50ml vials as I an with a 50/50 mix of each slurry and glycerin. I'll label them with what the yeast is, date it, and add what generation it is. I haven't gone beyond 3rd generation, I figure if I can get something like 15-20 pitches out of a pack of yeast I can leave it at that. I'll also label the cap of the vial too so I can identify them easily when looking at them from above.

Once they're all full I stick them in the fridge for 24 hours to cool. After that I'll take them down to my freezer and shake them all up again before sticking them into a styrofoam container that I keep in my chest freezer. The styrofoam helps protect the yeast from freeze / thaw cycles.

When I want to make a starter I try to plan it a few days in advance. I prefer to thaw the yeast vials in the fridge for a day, but soaking them in a bowl of water for an hour has seemed to work just fine as well. I make a mix of .1g per ml starter wort depending on my needs (usually back up to 140g in 1400ml or so) and pitch the thawed yeast. It's usually about done in 18-24 hours! That gives me enough time to cold crash it a bit so I can pour of the supernantant for my actual pitch into my wort.

This is definitely the recommended way to do it!

Also a related tip - for more portable dosing you can dissolve it into much smaller volumes (ie 10mg / mL), measure it out precisely with a 1mL/1cc syringe and store it in capped plastic centrifuge tubes.

That makes it easier you can hand out volumetric doses to friends, store them in your pocket for easy consumption later in the day, etc. I find 2c-b is one of the easier psychedelics to handle in social/public/crowded environments and it’s very redoseable, so it’s particularly useful to have a convenient way to take more on the go.

It’s also worth noting that 2c-b is a very hardy compound (like most phenethylamines) - it’s not as necessary to use any special water for it, it’ll stay potent dissolved in regular tap water for years. If you’re doing volumetric measuring with something more delicate like LSD then it’s very important to use water without any chloride, which will degrade it over time.

I'm ready for this question! I have a whole bookmark tab because I'm planning on building a vanity and redoing all of my storage. I'll give you a sneak peak into it (; Let me know if you want more! I have a bit more than a dozen of these things saved.


First up, acrylic drawer organizers!. Much cheaper than most other competition I've seen. I use these to house blush and bronzer and whatnot. If you guys can find a flaw in the first one I linked please let me know since that is what I'm planning on buying!


For samples, lots of people go for ammo boxes but I'm thinking of buying test tube racks/cases such as this or this. There's also a stainless steel options of the later version that look really pretty but are much more expensive and since these will be in drawers...I don't care quite that much.


If you do go for ammo boxes, however, this particular box has been mentioned several times in the past. It won't fit the longer or short and fat samples, but it'll do fine for most others. I don't care for it because of the color options, to be quite honest about it. It's a superficial thing and if you don't care I've seen many great reviews of this box.


For full-sized bottles, I've seen people use cake stands and pretty trays but since perfumes are light sensitive I plan on hanging a spice rack like this one inside a cabinet. Really you can hang it anywhere as long as it's out of light and humidity (so not in your bathroom!).

It's not a cheap atomizer but it works marvelously. First of all, it's surgical grade CNCed stainless so it's nigh indestructible. It's also pretty small relative to other potential choices. I think the real reason is that it's just the right diameter for convection, it's easy enough to build a coil to fill the whole oven--though shorting to the kanuelensockel walls must be carefully avoided, the end result is spectacular. I think whichever way you go, it's important to fill the entire air-path with thick wire. I found 22ga 2x twisted worked best, I only tried titanium but some people use stainless which has a lower temperature coefficient of resistance, and therefore, is less accurate for TC. Finally, though I like the enano stems, I think the stock A2-TM bowl conducts significantly more heat to the load, and consequently vapes more evenly. I was able to one-hit a bowl in an enano stem by torching it just until my herb started to brown on the outside, then hitting it with the Bulli-- but boy, was that irritatingly thick vapor.

If you go the route of the "phoenix" glass atty, I'd recommend trying to wind a coil around the bowl, between the bowl and the outer glass, designed so that air is drawn from above. That way, you get conduction and convection. That's been my dream for a while but I am not motivated to build anything better anymore =)

At home, I use it with an enano stem or gong stem so I can see the herb. Regardless of the bowl in use, I usually load it by sucking up the ground herb from my grinder, or a centrifuge tube.
I actually haven't used those specific tubes, I actually use 5mL tubes since even that's overkill for me, but you get the idea.

You're welcome -- glad I could help!

If you decide to go with large tubes, these are similar to the tubes I use, but there are cheaper options: 1, 2, 3, etc. It's important to look for tubes that are listed as either "sterile" or "autoclavable." I like the pre-sterilized packs because that's less work for me.

There are a lot of techniques out there, so sometimes it helps to list them out into categories with a few details underneath each. With a list like that, you can go through it all at a glance and decide what aligns with your budget, material availability, and level of effort/interest.

Let us know what you end up deciding to do and how it works out for you. I'm sure a lot of folks around here would like to see it!

Bottle preforms are great small tubes for keeping things dry

https://www.amazon.com/Soda-Bottle-Preforms-Caps-30/dp/B008MB1QNY

For a while you could buy redbull shots. They were a great small container as well

edit:correcting formatting.
Edit 2: always put rolls of tape in a baggy. When theyre hot they can ooze adhesive and make your kit a mess

I do a similar thing, but these are the tubes I use. I bought two sets of them several years ago and they still work great. I replace the caps every so often. For the rack, I just keep them in six pack holders and put them in the keezer. I fill the unused vials with StarSan solution and store them that way.

I'd also like to add that, after I have racked a new beer into the fermentor, I pour the leftover trub into a mason jar, and then let it sit in the fridge for a day. Usually the trub separates to the bottom leaving a fair bit of usable wort. I give it another quick boil just to make sure its sterile and then make a small starter of something. After pouring off much of the beer, I can usually get about 10 vials of slurry.

I am struggling with this too, so I will take notes from this thread (thank you).

What I am doing thus far:

tampon flasks because I found them online and thought they were hilarious, and my girls are similarly natured

A mini bottle of her favorite alcohol for each lady (they are all of age)

Custom compact mirrors that I found on etsy; I can customize one for each gal based on her interests (one is getting a disney themed, one is getting PSU, etc)

A necklace to wear for the wedding (so technically not a gift, but they are beautiful so hopefully they will like them anyhow)

Also providing mani/pedi the day before (well my MIL is gifting this to us, so SHE is providing that), hair and makeup for the service, and getting ready food (breakfast and lunch).

As far as other gift ideas though, I am completely clueless. I wanted to make little gift boxes or wedding survival kits for each of them, but I dunno yet.

Hey, thanks! Yes, that's the one I was thinking of. I just couldn't find it. Idk about better though. They're different for sure, but they're both made from bottle preforms, so the tube strength should be the same.

The pocket reel comes with:

• 1 pocket reel
  
• 4 fishing hooks
  
• 4 removable sinkers
  
• 2 metal spinner lures
  
• 3/4" bobber
  
• knot guide with directions
  
• 45' spool of fishing line
  
  The one I linked comes with:
  
  
• 1 Heavy duty plastic tube with screw top lid.
  
• 24’ of 20# monfilament fishing line
  
• 3 #2 Eagle Claw Hooks
  
• 3 #4 Eagle Claw Hooks
  
• 4 #3 Split Shot Lead Sinkers
  
• 4 #7 Split Shot Lead Sinkers
  
• 2 Slip Bobbers
  
• 2 Attached Bobbers
  
• 2 Various colored Jigs
  
  So, with the pocket reel, you get 4 hooks instead of 6, 1 bobber instead of 2, 4 sinkers instead of 8, metal spinners instead of jigs, but almost twice as much line and a "knot guide".
  
  Seems like about a wash to me. I should note that I don't have a horse in this race, I've never used either and am not affiliated with either shop. The kit I posted was one I found a month or so ago while looking for the one you posted.
  
  Personally, I went with neither and just bought some bottle preforms for about a buck a piece, filled a couple with the fishing gear I already had and used the rest for other camping gear: spices/oil for cooking, match case, pill bottles, tinder case, etc.

Oh gotcha. There are a bunch of use videos and articles about yeast propagating and yeast ranching that you can watch to learn more. After I grow up the population of yeast, I divide it and refrigerate them in either 50 ml sterile centerfugale tubes or in 1 pint Mason jars depending on size. I buy the centerfugale tubes on Amazon. All in all, It's easier than it looks and is fun to experiment with. As long as you pay extra close attention to sanitation and sterilization you should be fine.
Here is a link to the tubes I buy. SPL 50ml Conical Centrifuge Tube PP/HDPE, Sterile,Non - pyrogenic, Non - cytotoxic, DNase / RNase - free, Human DNA - free (Pack of 25) https://www.amazon.com/dp/B01KXX7NQM/ref=cm_sw_r_cp_apa_i_l0osDbCZ2N2KS

Bought some plastic vials off Amazon, fit perfect in my bong. I used an exacto knife that I heated with a lighter to cut into the plastic. Made a few different patterns, the wrap around one works really good, gives a nice clean pull.

Yes, those should fit as well. Hmmm, I may need to give that curved one a try, too.

As it happens, I also ordered one of the pieces in your second link, with the plastic mouthpiece ( https://www.amazon.com/Chem-Si-Solo-Glass-Drying-Straight/dp/B01M97O121/ref=sr_1_6?m=A2YWUIZGUW9D1Y&s=merchant-items&ie=UTF8&qid=1524575058&sr=1-6 ), so I have one on hand, and yes, it also fits the Sai with a section of cart cap as a seal. I'll post a pic when I have some time.

These were so cheap that I ordered a few others at the same time, so I have a few more coming. I'll post the ones that fit, but the one I highlighted does work great.

One thing I should have added is that a little rack to hold flavoring bottles helps a lot to prevent knocking the bottles over with your syringe. The little 8ml glass vials like you get from W.Labs are tall and light and easy to knock over. I use this one but anything like it should work. Another great tip someone posted here is to put your bottle of nic in a coffee cup when drawing into the syringe. Keeps it from knocking over and localizes any dripping.

Do you have stuff to make starters already?

Stir plate, flask (get two), dme. Pick up some plastic 50mL tubes, and start doing some starter harvesting to keep a few strains on hand that you like.

Fermentation temp control is something you really want to take care of. It's usually said that it's the #1 thing to improve your beer (along with starters). If nothing else, make a swamp cooler or a son of fermentation chamber out of a box or rubbermaid bin.

Here's a link to those tubes. They're pretty common, you might be able to find a better price than that.

They're food-grade (obviously) so they supposedly work well. Haven't used them myself though. These should only be used for starters though. After storage you're likely not going to have enough viability in a single vial for a healthy pitch.

The ones I have were actually being thrown out from a research building, so I am not sure the best source to get them, but they are called falcon tubes. Here is a link to some on amazon, though you can probably find a better deal elsewhere. Hope this helps!

Here's a post I wrote detailing how I slant yeast. The process is pretty simple, and only requires mason jars, test tubes, an innoculation loop, stove and pressure canner and a few consumables. I've tried several other methods for storing yeast, but this is by far the easiest, cheapest and most compact. You only need a pin prick's worth of yeast to create the slant, and you only have to maintain them every 1.5-2 years (which is also very simple). This makes it so you can accumulate quite the bank! I currently have a bank of 23 yeasts, and it fits in the size of a shoebox. The only thing I will note is that the test tubes in my blog can be expensive. I recently switched to these centrifuge tubes instead, as they are much, much cheaper, and they should work just fine, reading the comments, but I have not tested them personally yet, so have not updated my blog. The only downside to doing slants is it does take about 7 days to get a pitchable amount of yeast, so you have to be able to prepare ahead of time.

Oh wow, I'll have to give these a go. I've been using a few of the Nalgene Travel Bottle Kit bottles for olive oil, hot sauce, etc, and soda bottle pre-forms for batteries and some other stuff. But they're too big for most things like seasoning/spices, and not big enough for stuff like pancake mix.

Short answer if you just freeze yeast the freezing water solidifies and punctures cell wells, killing most of the yeast.

Long answer if you add a 50/50 solution of (water or beer) with food grade glycerin the water will get cold but never freeze.

My process:

Harvest yeast- overbuilding a starter is the easiest way or you could harvest and wash your yeast.

Decant Beer from your starter or use water and half fill a 1 pt mason jar and top off the rest with food grade glycerin. Boiling at this point is probably unnecessary but I do it anyway just to make sure no bugs get transferred in. Cool.

I then spray everything I use with Starsan and then dip everything I’m using in to the boiling water.

I use Soda Preforms but will switch to 1.5 ounce glasses once I burn through my preforms because I can boil them killing anything and not have to worry about melting plastic plus they’re cheaper.

I fill them halfway with my Decanted Yeast Slurry and let it settle. You want the settled yeast to be about half of the Preform which is approximately 100 billion cells. I then Decant excess liquid off and top off with your 50/50 (Water or starter beer) and glycerin.

Cap/Label place in an insulated bag with an ice pack to protect from freezing/thaw cycles and place in the freezer.

I use 1.5mL microcentrifuge tubes for my salt and pepper on short trips. I usually don't use much, depending on how the meals are planned. I'd probably just use more vials for longer trips or meals needing more seasoning - but 2.0mL. 5mL, and 7mL+ tubes are available as well. I really like the attached flip-up cap. Can't get lost, easy to open/close with one hand, and hasn't ever come open in the pack or unintentionally. The ones with caps that press on (don't screw on) are hard as hell to open, and when you do have a good chance of spilling everything in the process.

So the melting point of adex is between 81-82 degrees C. being as water boils at 100C you'll be fine using this method.
You'll first need some capillary tubes and a decent immersion thermoter

This is where it gets a bit tricky. I would probably use a glass beaker to boil the water so you're able to see clearly when the sample begins to melt. be sure to calibrate thermo and account for any discrepancy in the range.

anyway, this is how I've done it in the past. if anyone else has a more reliable or easier method im all ears.

I think a hot plate and a thermo gun would work well too..

I've found 50 mL test tubes like these are fantastic for storing 10 or so joints and keeping them from breaking. I usually just put it in my boxer briefs and have never had issues. Securities getting a bit tighter these days but luckily you shouldn't have too much of an issue putting a 50 mL tube up your butt if need be.

I got two packs of Omega yeast (OYL-500 & OYL-052) for free from my LHBS as they were packaged in January. How can I recover and store these? I was thinking a two stage yeast starter on my stir plate, cold crashing and pitching the slurry into one of these, then storing in the fridge. If I do that, how long will they last? And would it be a good idea to pitch them in another starter before use?

THESE are cheaper and more durable/waterproof. A little bit of spray paint or camo tape and it blends in just as well as the other mentioned containers. In my area we have a lot of waterways and these make GREAT paddle caches.

These fit nicely in your purse, and security never messes with them too closely.

>so I have just had a brilliant idea for hiding booze: inside a fake tampon applicator. They'll never know! I'm so grossed out at myself for even thinking of this.

it's literally a thing! lmao

I wanna bring this in... lol

You can buy vials from Amazon or [Goulet] (https://www.gouletpens.com/goulet-empty-ink-sample-vials/p/GP-10006). And you can get blunt syringes from [Amazon] (https://www.amazon.com/Duda-Energy-Syringepk001-Industrial-Syringes/dp/B00NDETMR2/ref=sr_1_4?ie=UTF8&qid=1485633133&sr=8-4&keywords=blunt+syringe) or Goulet as well. You can also use any small glass or plastic vial you might have, I recommend small spice or jewelry jars. You can often find them in craft shops if that's easier and more local for you. Blunt syringes aren't as easy to find in person, but you can often find wood glue syringes like this in any local woodworking or craft shops.

500 for $13! That's more like it! Thanks for the idea Mr. Goldfish

http://www.amazon.com/dp/B003ULPAU6

I bought a 50 pack of these plastic Centrifuge tubes for mixing on the go. One 50 mL tube holds almost exactly a single serving of Tailwind. Plus, I can fit two full tubes in the storage pouch of my Nathan SpeedDraw plus. I used this setup for a Marathon and a few trail races and it worked great. The tubes are so cheap you can dispose of them if you want, or save and wash them for reuse. Much better than the formula dispenser option you're looking at IMO.

Edit: Here's an updated product link to what appears to be the same item, but is in stock.

1. http://www.amazon.com/gp/aw/d/B00CLBWRCA?pc_redir=1407856945&robot_redir=1 It's a tube where you pour alcohol in it and put it in a faux tampon wrapper so you can sneak it around. In my case, I've used it to put my blunts in it for my boyfriend and I for Mad Decent Block Party this Saturday. (Currently on a t-break, excited to smoke again in a couple of days!)
   
   
2. Yes! I love that picture. I bought it from Salvation Army a couple years back. I use it as my blunt rolling station.

So I uh, cheat, and use Northern Brewer's Fast Pitch. I absolutely love this product as it means I can whip up a starter in ~5 mins before leaving for work in the morning (because inevitably that's the only time I remember I need a starter for later in the week). If you'd rather make your own starter wort, it's pretty simple - all you need is DME, and the measurement can be calculated here.

Otherwise, my method is the same as /u/pricelessbrew's above, which was originally from /u/brulosopher here. As I mentioned, I use centrifuge tubes for storing yeast - this actually was a method someone here suggested on a daily Q&A thread a few months back that I can't find now. Containers are cheap enough to only use once, and are pre-marked with volumes to be able to estimate cell count. Highly recommended.

These are the ones I use, they fit an 1/8th almost perfectly.

I’ve been freezing yeast for a couple years. The process in that link is a lot more complicated then it needs to be.

I use a variation of this process.

1. Build a 2L starter like normal.
   
2. Once Fermentation is complete cold crash and decant.
   
3. Fill 3/4 of a preform, lightly screw on the cap and place in the fridge.
   
4. Revisit the next day and decant till you have 1/2 filled with compacted yeast.
   
5. Top off with 1/2 Beer, 1/2 food grade glycerin.
   
6. Screw on lid, label, shake and place in freezer.
   
   Tips
   You’ll want to be as sanitary as possible.
   I can reliably fill 4 soda preforms.
   I’d recommend one have a different color cap to let you know you’re almost out of that particular yeast strain.
   I keep the beer/glycerin mixture in a mason jar and bring it to a boil from time to time since you won’t use as much of it as you’d expect.
   Save used preforms to re-use.
   Only do this for yeast you’ll use or have a hard time getting ahold of. You’re not saving money by saving yeast you’ll never use.
   If I plan on reusing yeast within 6 months I’ll wash the yeast and place in a mason jar.
   In my experience it takes the yeast a day or two longer to wake up once pitched into a starter. Make sure you build that time into your brew schedule.

Have you considered bottle blanks? Pretty cheap option and just like what White labs used for years. Bottle Blanks

I've found it's easier to smuggle alcohol in if you're female. The giant purse I carry to events is a black hole. Most guards only give it a cursory glace through. So if you're not female, get a female friend to do you a solid and sneak the booze in.

Soda Bottle Preforms and Caps (30/pk) https://www.amazon.com/dp/B008MB1QNY/ref=cm_sw_r_cp_api_i_kRgwCbRD41AA3

“All plastic soda or "pop" bottles start as a small plastic tube called a preform. When this preform is heated and blown into a bottle shape, it is ready to be filled with your favorite carbonated beverage.”

I usually go 100 billion - same as comes in a commercial yeast pack.

I save them back in my original White Labs vial, or in one of these.

https://smile.amazon.com/gp/product/B005Z4S2QU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

These work great.

Definitely looks like a geocache made from a soda bottle preform. would explain the 'fish eye lens' and the soda bottle style cap.

Warning - they do come in a BIG bag - 100 count. WAY too many for me to ever use. If you live in Seattle - come over and I'll give you a bunch.

-----
I've also ordered bottles on https://www.usplastic.com. You may have better luck there since you can by just the amount you need.

I picked up a 500 mL flask for this reason. I overbuild a starter, decant off 1/3 or so into the 500 mL and add more wort to top it up to ~300 mL. I also top up the 2000mL flask to build up the pitching starter. Once the 500mL flask ferments out, I cool and decant off the liquid, and pour them into vials that I picked up on amazon.

Oh man, does that mean these will fit as well?

Salt & pepper covers me most of the time. Occasionally I'll want olive oil. I use small plastic test tubes with screw lids. They are 5.08 grams and 10 cents each, and hold 15ml. For reference, that would be about 140 calories of olive oil.

The amazon link says 10ml, however a quick water test shows them holding 15-16ml.

They are strong and durable, and resistant to being crushed. Also really useful for medicine or other things you might need to bring along.

Or you can buy some test tubes from amazon pretty cheap and use that since it has an air tight cap.

They're plastic so its better than having glass

why dont you buy this. I know a few of my friends did it plenty of times and got it all in flawlessly

is this a shitpost? or do you just really like soda blanks?

I'm all for whatever reduces WL's cost but doesn't harm me.

I've heard somewhere somebody suggested soda bottle preforms. I've no experience with them but seems a good idea for making slants.
http://www.amazon.com/Soda-Bottle-Preforms-Caps-30/dp/B008MB1QNY

They are soda bottle preforms (or "baby soda bottles,) which are uninflated 2 liter soda bottles. Available here and on Amazon, and other places.

I must say that posting a "these just arrived in the mail" without providing a source is a little less helpful that it might be. OP? Your source?

Personally, i bought some soda bottle preforms (https://www.amazon.com/Soda-Bottle-Preforms-Caps-30/dp/B008MB1QNY) and overbuild starters, save a vial or two, and use that to rebuild starters. Havent bought yeast in a hot minute.

I make a starter for every yeast that I buy and then save a little bit in 50ml vials. If I ever want to use a yeast that I have I just create a starter 3 days ahead of brew time. I used to use mason jars, the 1/4 pint ones (4oz I think) but found out that these take up way less space.

I use these polycarbonate test tubes, then store them in the fridge. Ideally I'll be getting a small mini-fridge soon!

thanks for the article, this is what I bought

Have you looked into something like these?

Smart to have an actual tube of lotion.

If I was a girl I’d use these tampon flasks

2 litre soda bottles actually are shipped as preforms that can be expanded before they are filled. I guess heating them up without pressure returns them towards their original size?

Yeah dog...

These are the tubes I use

This is the rack I keep them in

You need to make some slants. Petris in the fridge dry up and end up with water matted on the surface.

check these out . I haven’t used they yet, and make sure you get a tray so you can PC them. I’ve used the glass ones, but those are really expensive.

It won't be impossible, it will just mean using a different container. I've been holding onto a ton of the tubes for a while for saving yeast. Also:

if you need more and want to stick with vials.

If you don't have a vape yet, get an Arizer, you won't regret it.

Also found these. Complete with a rack, and a spot on the vial to write on.

These are a thing

Have a guy place it next to the frank and beans. A bulge is normal and the door man isn't likely to touch there. Or there's always the Wine Rack or the tampon flask.

Doing some sort of shot into these might be appropriate. They're cheap enough and a bit of gold paint from craft store might be enough to glam it up.

They are actually made for soda bottle production. You can usually find big packs for cheap.

Or just stick some of these in your girlfriend's purse.

Assuming your pints are partially filled with spent wort, you can siphon that off and just fill old White Labs tubes with the yeast. If you don't have any old tubes kicking around you can just grab some of these

I run a homebrew store and absolutely hate the damn vials. Bags are much easier to keep track of, arrange and take less space.

Cheap 50ml tubes and a rack for them.

They aren't pressure safe like the preforms are, so make sure you're all gassed off before you seal it for long term.

I usually keep it in a jar with the lid loose for a while before I decant and move the slurry over to a tube for longer term storage.

Right now I've got only six strains, but I only recently started harvesting from starters. My go-tos tend to be:

• WY3711
  
• WY1010
  
• WY1272
  
• WLP007
  
• WLP090

Are you looking for just the pouch or a complete kit? Bumps and bruises or blowout kit?

I don't run it on the outside of my bag, but my EDC medical setup is a CAT, Israeli bandage, trauma shears, and some everyday meds (IB, benadryl, etc) in a crush-proof tube shoved into an M16 magazine pouch.
