A vacuum resistant flask or woulf bottle must be placed between the manifold and vacuum pump. (Supplied without Wolfs Bottle and Vacuum/ Pressure Pump). These units are used for sterility testing when the membranes filter is to be removed from the holder for incubation in culture media. Though only vacuum is required for filtration, some pressure is required for flushing liquids.
