Conical Flaks Pyrex Glass – Laboratory Glassware

A conical flask (also known as an Erlenmeyer flask) is a type of laboratory glassware with a conical body, a flat bottom, and a cylindrical neck. The Pyrex brand is known for its high-quality, heat-resistant borosilicate glassware used in laboratories. Below are typical specifications for Pyrex conical flasks:
