Product Description
Run vacuum filtrations with a flask built to handle the pressure. Heavy-wall borosilicate glass withstands high vacuum, giving you a reliable collection vessel for Buchner funnels and vacuum filter setups in chemistry, microbiology and quality control labs where routine filtration is part of the daily workflow.
This listing is for catalog number 1780T-1000: Glass Filtering Flask, 1000 mL. Each flask has a heavy-duty rim to resist chipping, permanent white graduations and a large marking square for labels. The side-arm port for vacuum tubing has a 10 mm outside diameter, and the neck accepts a No. 8 rubber stopper, sold separately. Capacities of 300, 500, 1000 and 2000 mL are available, each sold individually. Add it to your LIGHT LABS order and keep your lab stocked.
