Whatman Mini-UniPrep™ Syringeless Filters.
The Whatman Mini-UniPrep syringeless filters provide a faster and easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC) analysis and other applications.
Whatman Mini-UniPrep is a pre-assembled filtration device consisting of a 0.4 mL capacity Poly Propylene 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.
The result is a filtered sample in a 12x32mm (2ml auto-sampler vial) format which can be placed on instruments using the most common auto-sampler format on the market.
The device can be used either manually or with a compressor unit. The 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 accommodating 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.
Whatman Mini-UniPrep syringeless filters are available in Clear and Amber formats. Additionally pre-slit septa variants are also available for auto-sampler units with sensitive auto-sampler needles.
