The Pocket Chemist is a stainless-steel laser-cut credit-card sized chemistry stencil, ruler and reference designed to help you fly through your homework with immaculate reactions and reduce simple mistakes in calculations.

The front includes metric and imperial rulers, arc and angle drawing tools and the 8 most common molecule shapes in organic chemistry. Flip it over for a full periodic table, 10 physical constants, 11 fundamental equations and 16 common unit conversions so you never need to look these up again.

Transform your reaction sketches:

1. Stencils for cyclohexane, benzene ring, cyclopropane, cyclobutane, cyclopentane and a carbon chain which fit most 0.7mm pens, pencils and smaller.
2. Stencils for chair conformation and boat conformation (flip for ring flip).
3. Angle measurement for precise bond angle drawings.
4. Imperial and metric straight-edge to 85 mm.
5. Arc and circle drawing tools with 1/8" or 5 mm resolution.

Save time with laser-engraved references:

1. Full periodic table with atomic number reference in each period (row) plus a reference Krypton electron configuration.
2. 10 physical constants in chemistry including the molar gas constant in three different unit forms.
3. 11 fundamental chemistry equations.
4. Temperature, mass and pressure conversions.
5. Six important metric order of magnitude prefixes.
6. 42 digits of Pi. Just for fun.

Bonus functions for everyday carry:

1. Enamel-coated 0.5 mm stainless steel laser-cut for precision molecules and laser-engraved with text that won't rub off.
2. Phone stand slot (insert another sturdy credit card).
3. QR code which will link to rotating monthly Easter-eggs on a hidden GLG page.
4. Fits any normal credit card or ID holder. TSA compliant and more compact than a standard 6" engineering scale ruler.
