Filtering Flask, 500mL, Borosilicate Glass

This 500 mL filter flask is made from borosilicate glass and features a side arm for vacuum connection. The neck inner diameter measures 28 mm. The borosilicate glass construction is autoclavable with superior chemical durability. Heat tolerances are: Strain Point 515°C, Annealing Point 565°C, and Softening Point 820°C. Filter flasks are used in vacuum filtration setups where a reduced-pressure environment is needed to accelerate the filtration process.
