Pall SKU: 4521

Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - 4521

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Chemically inert PTFE achieves sterile-grade retention in gas and vent service while staying chemically inert against solvents, acids, and alkalis in service and blocks aqueous ingress in vent applications. Polypropylene construction maintains a low-dead-volume internal flow path while maintaining housing integrity through the filtration run and resists degradation from routine sample matrices. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown
• Absolute pore size rating gives consistent results across protocols
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Low extractable contribution protects sensitive downstream analyses

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection.

• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• 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
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
