Hand Vacuum Pump - without gauge

This economy hand vacuum pump can be effectively deployed in the chemistry classroom to remove gas molecules from a sealed container so as to generate a partial vacuum.  The pump can also completely remove liquid from a sealed container, creating a vacuum in an enclosed space.

This vacuum's pump rate is 15ml per stroke. It will displace up to 725ml of air and the unit is fitted with a valve to release the vacuum without disconnecting the pump.
