Jednostki filtracyjne UniPrep

Jednostki filtracyjne UniPrep przeznaczone są do filtrowania i przechowywania próbek laboratoryjnych. Są szybką i łatwą w użyciu jednostką typu all-in-one, zbudowanym z tłoka, filtra i fiolki. Zastępuje wiele filtrów strzykawkowych pojedynczą jednostką filtracyjną.
UniPrep Syringeless Filters are preassembled filtration devices for the filtration and storage of laboratory samples. These devices are quick and easy to use and feature a plunger, filter, and vial in one unit. They replace syringe-coupled filtration devices with single, disposable units.

• Integral storage vial saves time and minimizes laboratory waste.
• Built-in glass fiber prefilter means even difficult samples are quick and easy to prepare.
• Choice of membranes for wide sample compatibility.

UniPrep devices consist of two parts: a test tube and a filter-plunger. The design incorporates a prefilter and a membrane into the tip of the plunger. When the filter plunger is pressed through the liquid placed in the test tube, positive pressure forces the filtrate up into the reservoir of the filter-plunger.

UniPrep devices function in a similar way to the Mini-UniPrep. However, UniPrep does not contain a septum in the cap and can be used to filter larger volumes (1 to 5 ml).

The UniPrep Syringeless Filter is selected based on compatibility with the sample in use. In manual operation, the filter-plunger, after the tip comes in contact with the liquid, is slowly pushed into the test tube until it stops at the bottom. The UniPrep is emptied either by decanting into a sample or autosampler vial or by drawing the filtered sample into a syringe for manual injection into an instrument.
