G.S.C. International Filtering Flask Vacuum Pump Kit

More economical than an electric vacuum pump.

This Filtration Kit allows rapid separation of mixtures via vacuum filtration. The stopper is cut to hold a Buchner funnel. The hand-operated vacuum pump simplifies vacuum filtration, eliminating the need for a water source or vacuum aspirator. The pumping rate is 15 ml per stroke, and will displace up to 725 ml of air. The pump is fitted with a valve to release the vacuum.

Livraison: Kit includes borosilicate filtering flask (500 ml), vacuum pump, Buchner funnel, filter paper (7 cm), connection tubing and rubber stopper.
