(Part 2) Reddit mentions: The best test lab tubes

https://www.amazon.com/gp/product/B00RKMWZOA/

that's what i used, fit the coil as-is perfectly.

Plastic can be ok. Go to a headshop and get a glass slide and bowl or check amazon even. Here...

4" Silicone Downstem Stem 14mm Female to 18mm Male (Light Green) https://www.amazon.com/dp/B078L1ZD6G/ref=cm_sw_r_cp_apa_i_bpm1CbM8S1NJ3

Get one of those, or a glass one if you prefer although it'll be less flexible with making a good seal.

They also have multi packs of glass bowls for like $5.

Or even better

It looks like it would function well, but like everyone else said, probably not safe to smoke much out of.

Ill even ship you a cheap downstem/bowl if you need. Or even a little bong if its cheap enough.

Amazon sells plastic ones with caps that you could order, but it looks like a lot of them come in packs of 50. Here's one that's a pack of 12 for $10. Your local big box store might also sell them? As long as it's plastic, has a rounded bottom and a cap it should be fine.

They don't have to be specifically for the test kit

Just mark them halfway down with a sharpie or something. These might actually be better since they have screw tops.

The one review says that they're using them for aquarium testing.

Erm, if you have 7 of them, maybe fill 2 or 3 with the same ink? ;) (Teasing!)

You could get something like the following to store your re-sealed cartridges in so you don't have to worry about leaks:

...or a small food container.

I love the idea of plastic test tubes too https://www.amazon.com/dp/B07HCF8CYM/ref=cm_sw_r_cp_api_i_3JkjDbVR5SDAB

I think it was this one, it was the only pack I could find :) UEETEK 15pcs 110ml Flat-Bottomed Plastic Clear Test Tubes with Screw Caps Candy Cosmetic Travel Lotion Containers https://www.amazon.com/dp/B0796D3JXR/ref=cm_sw_r_cp_apa_i_zWFOCb6TGK737

> Can this be done safely

I highly doubt it. And even if it could be done safely, I'm sure it's not worth the effort.

You really only need the screw base from the C9 bulb. Everything else is negotiable.

So I say break the glass off the C9 bulb. Then use nippers to cut the filament off the support wires. Solder an LED and resistor where the filament used to be.

Then find some kind of clear plastic tubes that are the right diameter to fit into the C9 screw base. (Maybe you can find some cheap plastic test-tubes of about the right diameter and cut them to length.) Epoxy them into the metal screw base. Now you have a "bulb" designed to run on low voltage.

Then just wire all the sockets up with 5V.

Couldn't find the exact set I got (wasn't on amazon) but [here] (https://www.amazon.com/Scientific-Plastic-Container-Cylindrical-bottom/dp/B01M8M33G4) is an example, and [here] (http://imgur.com/a/qlm64) is what I have. I bought them about a year ago and can't find the exact site, if I do I'll edit it in, but the ones on amazon should do the same thing.

EDIT: [Sauce] (http://www.lcmlab.com/SearchResults.asp?Cat=23) I bought the 17mm. Don't be me and buy yourself a 12mm. I'm sure mine will be fine I'm just a tad ocd and I hate knowing I bought a greater-than-the-diameter set. Oh well.

edit 2: ordered the 12mm

25ml Clear Flat Glass Test Tubes with Cork Stoppers, 20×100mm, Pack of 30 by DEPEPE https://www.amazon.com/dp/B07DB44HJT/ref=cm_sw_r_cp_apa_whC.BbK00691D going with these cause it's cheap. Then just use a little card on them that say the potion name and tie it with some twine.

buy ALL of them!

I'll buy Quarter, dime, and half dollar coin tubes and start feeling them up. Started with quarters, then after filling a couple of tubes I went to dimes, then half dollars.

No they're 15mm x 125mm from Amazon: United Scientific TT9800-D Borosilicate Glass Test Tube with Rim, 15ml Capacity (Pack of 72) https://www.amazon.ca/dp/B00ES3PY0G/ref=cm_sw_r_cp_apa_UDAxzbZPTAY4P

Test tubes essentially, with screw caps. Plastic would be lighter, maybe less durable.

Test tubes like these tubes

Look for lab vials or test tubes.
See here: https://www.amazon.com/Buytra-Plastic-Container-Centrifuge-Graduated/dp/B0779RPGRM
If these are not the ones you look for try the given keywords and scroll through Amazon, there are a lot of different variants.

For spices, you can get test tubes with a rack and cork stoppers off Amazon, or at a local scientific supply surplus. Like this.

For those of us you can't drop that much cash:

cheap alternative


modernish looking rack


wire racks of various size and color are available

Complete the set with 5ml water pippets and 14ml test tubes.

Search for plastic screw-top tubes. Here’s an example: https://www.amazon.com/gp/aw/d/B075K7J8DZ/ref=mp_s_a_1_1?ie=UTF8&qid=1519473917&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=plastic+screw+top+tubes&dpPl=1&dpID=418fRaUL26L&ref=plSrch
