Academy Borosilicate Filter Flask – 500ml (With Glass Sidearm)

The Academy 500ml Filter Flask is part of a new, affordable, and high‑quality range of laboratory glassware developed for reliable use in educational and laboratory environments. Manufactured from durable borosilicate glass, this flask is designed specifically for vacuum filtration and other suction‑based procedures commonly carried out in school science laboratories.

Featuring a heavy‑walled construction, the flask provides enhanced strength and safety when operated under reduced pressure. An integrated glass sidearm allows connection to vacuum tubing with an 8mm internal diameter, making it compatible with standard laboratory vacuum pumps or water aspirators. Borosilicate glass offers superior chemical resistance and excellent heat stability, ensuring long‑lasting performance even with frequent classroom use.

With a generous 500ml capacity, a 29mm narrow neck diameter, and a 34mm upper neck diameter, this filter flask is well suited to larger‑scale filtration tasks, demonstrations, and advanced student practical work.
