PTFE Hydrophilic Membrane Filters, 0.22 um, 150mm, Nonsterile, 50/Pk SKU: SF13843

Polytetrafluoroethylene (PTFE) Membrane Filters, 0.22µm, 150mm - SF13843

Designed for the stringent demands of cell culture and biological assays, the Polytetrafluoroethylene (PTFE) Hydrophilic Membrane Filters, 0.22um, 150mm, Nonsterile, 25/pk offers validated bacterial retention for confident sample preparation. To achieve this medical-grade standard, the filter utilizes a Polytetrafluoroethylene (PTFE) membrane that provides a sharp 0.22 cutoff necessary for sterilizing biological fluids. To ensure experimental consistency, the high-quality material provides uniform flow and predictable retention rates across the entire surface area. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (standard) / hydrophilic (treated) affinity
• N/A (Chemically Inert) characteristics
• Universal resistance to aggressive organic solvents, strong acids, and alkalis
• Hydrophobic version requires alcohol pre-wetting for aqueous solutions
• 0.22 rating suitable for sterile filtration

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
