Mini-UniPrep™ syringeless filters, simple, innovative, convenient, is a pre-assembled filtration device consisting of a 0.4ml capacity chamber and a pluger. The plunger contains a filtration membrane at one end and a pre-attached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged providing an air-tight seal. Within seconds the Mini-UniPrep™ can be placed into any approved autosampler for injection into your instrument.
