SIMSII PTFE Syringe Filter 0.22 um Sterile Pack of 50 Filters

SIMSII Non-Pyrogenic Sterile Hydrophobic PTFE Syringe Filter, 0.22 µm Pore Size, 25 mm Diameter (S25PTFE022H) – Pack of 50 Filters

The SIMSII Hydrophobic PTFE Syringe Filter (S25PTFE022H) is a sterile, high-performance filtration device engineered for critical laboratory sample preparation, aggressive organic solvent clarification, and sterile gas venting. Featuring a 25 mm diameter hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.22 µm pore rating, this filter exhibits exceptional chemical compatibility with strong acids, alkalis, alcohols, and aggressive organic solvents. Encapsulated in a medical-grade polypropylene housing with low extractables, the filter utilizes standard Luer-lock inlet and slip-outlet connections to withstand high backpressures during manual or automated syringe dispensing. Individually blister-packed and pre-sterilized via gamma irradiation, the S25PTFE022H ensures non-pyrogenic performance, making it ideal for HPLC sample cleanup, gas venting, and sterile air filtration in sensitive analytical chemistry and biopharmaceutical applications.

Technical Performance & Structural Attributes

• Chemically Inert Hydrophobic PTFE Membrane: Broad chemical resistance enables filtration of aggressive solvents, organic reagents, and corrosive solutions without membrane degradation or leachables.
• Sterile & Non-Pyrogenic Packaging: Pre-sterilized via gamma radiation and individually blister-packed to preserve aseptic integrity and eliminate sample cross-contamination.
• High Operating Pressure Housing: Ultrasonically welded medical-grade polypropylene housing resists structural bursting and bypass leaks under high manual filtration pressures.
• Dual-Purpose Gas & Organic Solvent Filtering: Hydrophobic nature acts as an effective air/gas moisture barrier while allowing rapid passage of low-surface-tension organic solvents.
• Standardized Luer Fitting Interface: Threaded female Luer-lock inlet ensures a leak-tight connection to standard syringes, while the male Luer slip outlet facilitates precise dispense control.
