RephiQuik PTFE Non-sterile Syringe Filter


RephiQuik PTFE Non-sterile Syringe Filter

A PTFE syringe filter RJF1322NH/RJF3222NH/RJF1345NH/RJF3245NH uses a hydrophobic PTFE membrane in a high-quality polypropylene (PP) housing, free of any adhesives. The membrane is biologically and chemically inert, extremely low in extractable. Its unique design ensures no leakage of particles to the down-stream side of the membrane. The filters are resistant to the destructive effects of organic solvents, concentrated acids and bases, or other aggressive chemicals for which other membranes are unsuitable. This RephiQuik PTFE syringe filter RJF1322NH/RJF3222NH/RJF1345NH/RJF3245NH offers the optimal balance of a large effective filtration area with a low hold-up volume.
