About Borosilicate Glass Filtering Flasks

This heavy wall borosilicate filtering flask is designed with a heavy-duty rim and a bolt neck with tubulation for enhanced durability. The flask features graduations printed in durable white enamel for easy measurement. It is manufactured from low-expansion Type 1, Class A Borosilicate 3.3 glass, complying with ASTM E438 standards. This low alkali glass consists of approximately 81% silica, 13% boric oxide, 4% sodium oxide, and 2% aluminum oxide, with virtually no magnesia-lime-zinc content and only trace amounts of heavy metals, ensuring excellent chemical resistance.
