Reddit mentions of Caffeine Beaker Mug

Not really an answer to your question, but if you know she's in to coffee she would probably love this mug with a couple of glosses and a mascara inside. Or really any makeup product you think she'd like. That would open up your giftie possibilities while still hugging a theme you know she'll appreciate.

How about:

• Anything from the Giant Microbes store
  
• Heart & Brain Body Language Comic ($15)
  
• The Awkward Yeti Bowels "Soon" Mug ($16)
  
• The Awkward Yeti Common Grounds Mug ($16)
  
• Or a beaker mug, of course ($14)
  
• Lab shot glasses ($12)
  
• These brain specimen coasters ($15)
  
• Something from Rachel Ignotofsky's Women In Science Series ($10-$20)

I would suggest a mix between necessities and more so some wants. Example: His favorite cologne, socks, razor set, shampoo/conditioner and his favorite snacks/junk food. Maybe print out a picture of the two of you together if you have one (if not, im sure he'd love a picture of just you as well) and frame it? Candles are a safe choice too if you know what scents he enjoys.
