Acro Disc Syringe Filters w/ PTFE Membrane - 0.2um, 25mm, 200/Pk
Pall SKU: 4225

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

Pall Corporation engineers proprietary membrane media and the Acrodisc housing platform, purpose-built for demanding analytical and bioprocess workflows. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Chemically inert PTFE achieves sterile-grade retention in gas and vent service while blocking aqueous ingress in vent applications and resists attack from the harshest process chemistries. The polypropylene housing contributes minimal extractables to the filtrate and routes flow to minimize backpressure in service. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Chemically inert against aggressive solvents, strong acids, and alkalis
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Absolute pore size rating gives consistent results across protocols
• Filters aggressive organic solvents without swelling or breakdown
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.

Hydrophobic

• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids, ensuring compatibility with the harshest synthetic reaction mixtures
• Cryogenic Fluids - Delivers consistent performance in extreme temperature environments, filtering cryogenic liquids with exceptional reliability
• 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
• Gas Filtration - Ensures sterility in air and gas lines for fermentation tanks, preventing the introduction of airborne contaminants
