American Educational 7-880500-A Filtering Flask, Bomex Brand Clear Borosilicate Glass, 500mL Capacity

The American Educational 7-880500-A 500mL filtering flask is used to create a vacuum within a flask for filtering solutions. A barbed side arm accepts a vacuum hose. The mouth accepts a #8 stopper (sold separately). This flask is made of Code BJTY 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 ISO 3585, Type 3.3 specifications for borosilicate glass. Filtering flasks, sometimes called vacuum or Buchner flasks, are used for filtering solutions using a vacuum source, 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.
