Mini-UniPrep Syringeless Filters

Mini-UniPrep Syringeless Filters

The Whatman® Mini-UniPrep™ syringeless filters with durable plastic cap, provide a faster, easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC) analysis. In fact, Mini-UniPrep™ lets you prepare samples in one third the time required by other methods. Add up the time savings, plus the money saved from cutting multiple consumables out of the sample preparation process and you’ll see huge benefits for your laboratory.

Mini-UniPrep™ is a pre-assembled filtration device consisting of a 0.4 mL capacity chamber and a plunger. 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.

The device can be used either manually or with one of the compressor units available. The new multi compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep™ device is designed to fit into any autosampler designed to accommodate 12 x 32 mm vials. Alternatively the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer.
