#4500 Deluxe Filtration Kit with 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. It is more economical than an electric vacuum pump. The pumping rate is 15ml per stroke and will displace up to 725ml of air. The pump is fitted with a valve to release the vacuum.

The kit is provided in a reusable foam lined box with a compartment for each component of the kit.
