Volumetric Flasks, Class A, Low Actinic Amber, As Per USP Standards

Machine-blown bodies and heavy-beaded, heavy-tubing necks are tooled for standard taper stoppers on these flasks. The graduation line is clean and lasting, and the labeling is legible thanks to large white block characters. A huge marking square is also included in each flask. Light-sensitive items are protected by low-actinic amber glass. A glass standard taper stopper is included with each size.
