Solid Metal Solvent-Proof Chemistry Stencil: Sturdy and low-profile design eliminates the need to handle a bulky plastic stencil in tight workspaces. Ideal for chemists, biochemists, and organic chemistry students. Use it in the lab, during study sessions, or when drawing chemical reactions. This multifunctional tool fits in your pocket and supports molecular structure drawing and precise measurements. Makes a thoughtful graduation or welcome gift. Better Molecules In Less Time: Create clean, professional-looking chemistry diagrams efficiently. Draw accurate reactions quickly using benzene ring, boat, and chair conformation templates. Use the built-in ruler for consistent bond lengths to substituents and functional groups. Serves as both a straight edge and a molecular template, improving accuracy and saving time. Impress peers, instructors, and teaching assistants with neatly drawn reactions. A Joy To Draw With: Precision-cut openings with smooth, rounded edges work seamlessly with most 0.7mm pens, pencils, and smaller writing instruments without damaging lead. No snagging or rough edges. The stainless steel construction provides stability and prevents shifting, even in drafty environments. Delivers a smooth, frustration-free experience whether sketching, drafting, completing homework, or working on detailed chemical engineering projects. Bonus References Engraved: Quickly access common unit conversions such as grams to moles and Torr to mmHg. Includes key chemistry formulas like the Ideal Gas Law and Nernst equation, along with fundamental constants including Avogadro's number, Planck's constant, and Pi to 41 decimal places. Essential references are conveniently engraved for easy access during calculations.
