Acro Disc Syringe Filters w/ PTFE Membrane - 0.45um, 13mm, Male Slip Luer Outlet, 300/Pk SKU: 4422

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 4422

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Syringe Filters offers a robust solution for extending instrument life. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 0.45 rating remains consistent even under pressure. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

Hydrophobic

• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
