Vhen you buy Merck Laboratory < Reagent Gases you get a quality product with three extras: Extra safety. Extra convenience. Extra bench space. Extra safety because the cylinder is self-supporting, compact in size, and color-coded. Extra convenience because it handles like a standard reagent bottle but dejivers twice the volume of a lecture bottle. Reduces order and handling frequency 5 0 % . Extra bench space because it's shorter than a lecture bottle, narrower than a sphere, and has no ring stand to take up room. With all these extras in the cylinder, you could say we've introduced a new standard cylinder to the industry. Besides ample stocks, your local Merck distributor also has something extra for you. A colorful, ready reference file containing 15 technical data sheets with actual-size reproductions of the cylinders. It's all free. Call him. He's expecting you.
