Regular price $11.50 Sale

A chemistry molecule stencil and textbook reference that fits in your pocket.

Sketch immaculate reactions with the benzene ring, boat and chair conformation stencils. Turn in professional-looking chemistry homework and focus on the reaction, not how to draw it.

Use the straight edge and angle measurement tool for getting bonding angles just right. Flip it over for chemistry unit conversions, fundamental equations and the most-used physical constants!

This laser-cut and laser-engraved 0.5 mm enamel-coated stainless steel card fits any normal credit card or ID slot and is built for a lifetime of use and abuse.

As featured in:

It's a really interesting thing.

As a student living in a dorm, I hate to keep a lot of things, but I love this item because it's only the size of a card! Art templates are usually made of plastic, so they break easily, but this The Pocket Chemist is strong because because it is made of iron, so there is no need to break it. I first got to know tihis on Instagram, and I bought it because I thiought it might help me. Currently, I often use it my homework.

So cool!

Got mine fast in 4 days from my order! (in the US) I'm blown away that something could be so much better designed than anything similar out there. There are a few other molecule stencils on Amazon but they are gigantic, made of cheap flexible plastic and don't have all these useful conversions and constants on them. Excited to support this new company and will follow along to see what they come up with next!

Useful little tool makes chemistry homework easier!

Very glad I found this. The molecule stencils are the perfect size and easy to use. My homework looks much more professional than before! Another unexpected thing I found is that it's easier to stay focused on my homework since I do not have to look up the constants and conversions on my phone (and then get sidetracked by notifications). Sturdy metal feels like it will last a long time. My homework buddies saw it and ordered there own!
