Solid Metal Solvent-Proof Chemistry Stencil: Sturdy and low-profile so you don't have to fumble with a tablet-sized flimsy plastic stencil in your limited work space. Designed for chemists, biochemists, and organic chemistry students! Whether you're in a chemistry lab, tackling Orgo homework, or sketching chemical reactions, this multifunctional tool is always in your pocket to help. From drawing molecular structures to precise measurements, it also makes an ideal graduation or welcome gift. Better Molecules In Less Time: Turn in professional-looking chemistry homework and focus on the reaction, not how to draw it. Sketch immaculate reactions in seconds with the benzene ring, boat and chair conformation stencils while using the ruler for consistent bond lengths to substituents and functional groups. A perfect straight-edge that doubles as a molecular drawing template - save time with precision. Plus, your colleagues, professors or TAs will love how neatly drawn your reactions are! A Joy To Draw With: Smooth-glide precision-cut stencil openings have rounded edges to fit most 0.7mm pens, pencils and smaller without cutting into pencil lead. No more snagging or rough edges! Plus, the weight of the stainless steel card keeps it from shifting around with a draft in the room. Whether you're sketching, drafting, tackling chemistry homework, or a full chemical engineering design project, this stencil finally gives you a frustration-free drawing process. Bonus References Engraved: No more fumbling with conversion factors! Quickly find equivalents between different units-grams to moles, Torr to mmHg, and more. Whether it's the Ideal Gas Law, the Nernst equation, or a simple molarity calculation, these essential formulas are right at your fingertips. Plus it has Avogadro's number, Planck's constant, and Pi to 41 places past the decimal! These essential chemist
