Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.45um, 25mm Autopack Tubes (25/Pkg 200/cs) SKU: AP-4518

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - AP-4518

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Syringe Filters offers a robust solution for extending instrument life. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

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
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
