This hat features the essential skills any organic chemist, student or expert, will use when performing a reaction. Color-coded graphics make it easy to explain what is happening: From left to right, 1) setting up a reaction, 2) monitoring the progress of a reaction with thin-layer chromatography (TLC), 3) performing a workup to extract some of the byproducts, and 4) purifying the crude material using column chromatography to yield a pure product. A classic and comfortable way to show off your chemistry pride outdoors or in the lab! A perfect gift for any chemistry graduate, BA, BS, MS, or PhD! • 60% cotton, 40% polyester • Mid-profile cap with a low-profile embroidery area • Structured, six-panel cap • 3.5″ crown (8.9 cm) • Hard buckram front panels • Mesh back • Permacurv® visor, matching undervisor • Plastic adjustable closure • Head circumference: 21⅝″–23⅝″ (54.9 cm–60 cm) • Blank product sourced from Vietnam or Bangladesh
