Academy Borosilicate Filter Flask – 1000ml (With Glass Sidearm)

The Academy 1000ml Filter Flask forms part of a new, affordable, and high‑quality range of laboratory glassware designed for reliable use in school science laboratories and prep rooms. Manufactured from durable borosilicate glass, this large‑capacity filter flask is ideal for vacuum filtration and other suction‑based applications where strength and safety are essential.

The flask features a heavy‑walled construction to provide added security when used under reduced pressure. An integrated glass sidearm allows easy connection to vacuum tubing with an 8mm internal diameter, making it compatible with standard laboratory vacuum pumps and water aspirators. The borosilicate glass construction offers superior chemical resistance and excellent heat tolerance, ensuring long‑lasting performance under frequent classroom use.

With a generous 1000ml capacity, a 35mm narrow neck diameter, and a 45mm upper neck diameter, this filter flask is particularly well suited to larger‑scale filtration tasks, demonstrations, and advanced practical work.
