Chemglass CG-1506-23 Glass 1000mL Heavy Wall Single Neck Round Bottom Flask, with 24/40 Standard Taper Outer Joint

The Chemglass CG-1506-23 1000mL heavy-wall round-bottom flask is used for uniform liquid heating. The single neck has a 24/40 standard taper outer joint, and has a 130mm diameter body. Round-bottom flasks provide uniform heating. This flask is made of clear borosilicate glass for durability, chemical- and temperature-resistance, and high mechanical strength under harsh conditions, such as mechanical washing. Borosilicate glass has a low coefficient of thermal expansion and is resistant to thermal stress. The flask meets ASTM International E438, Type 1, Class A specifications for low-expansion borosilicate glass. Boiling flasks are used for heating and boiling liquids, quality testing, sampling, and research, and in lab applications in chemistry, education, research, and life science applications.

Flasks are glass or plastic containers for storing or collecting chemical samples or solutions in scientific laboratories. They come in a variety of sizes and shapes and are designed for a wide range of scientific processes. Erlenmeyer flasks, introduced by German chemist Emil Erlenmeyer in 1861, are shaped like a cone with a wide, flat base that narrows to a neck opening, which can be closed with a stopper or cap.

Chemglass manufactures laboratory glassware and equipment. The company, founded in 1946, is headquartered in Vineland, NJ.
