Description:
Cytiva Whatman UN113UORG UniPrep 0.45uM PTFE Syringeless Filter with GF Prefilter. 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. 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. 50/pack.
Applications: Sample preparation. Difficult-to-filter samples. Quick filtration of samples. Pharmaceutical samples. Content uniformity. Drug cleanup prior to injection during dialysis in animal studies. HPLC sample prep. Ion chromatography. Chemically inert PTFE membrane for filtration of samples containing > 50% organic solvent.
Pore Size (µm): 0.45
Membrane: PTFE
