Kimax® Schellbach buret. Conventional Shellbach burets employ a blue line on a broader white band running vertically behind the scale to create an optical effect which causes the meniscus to assume an apparent form. The meniscus is read at the narrowest point of the blue line just the true meniscus. Kim-Kap® dust cap is included. Scale is durable black ceramic enamel. Replacement stopcock is 6-41500F-2.
