Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 200/Pk - AP-4225

Pall's engineering and quality infrastructure extends from its process-scale filtration systems to its laboratory devices. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size and filters aggressive organic solvents without breakdown. Polypropylene construction maintains a low-dead-volume internal flow path while resisting degradation from routine sample matrices and holds a reliable seal against the membrane edge. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists stress cracking from aqueous salt and buffer solutions
• Optimized internal geometry minimizes backpressure in service
• Tough polypropylene body tolerates repeated handling at the bench

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 so your downstream method starts with a clean sample.

Hydrophobic

• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• 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
• Venting Applications - Prevents moisture and particulate intrusion in sterile tanks and vessels, ensuring a contaminant-free storage environment
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
