Filtering Flask, Borosilicate Glass

Heavy-wall filtering flasks — also called Büchner or vacuum flasks — made from borosilicate glass. The side arm connects to a vacuum source to draw liquid quickly through a filter, cutting filtration time dramatically.

• Borosilicate glass, resistant to thermal shock
• Side arm for vacuum tubing
• Heavy wall to withstand reduced pressure
• Available in 250 ml, 500 ml, 1000 ml and 2000 ml
