Pall Acrodisc PTFE Syringe Filters, 1 µm, 25 mm, 200/Pk - 4226

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. Syringe filters mount on a syringe to clarify a sample in a single manual pass. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis in service while clarifying solvent streams at the rated pore size and blocks aqueous ingress in vent applications. The PP housing prevents sample bypass under rated operating pressure while resisting aqueous acids, bases, and alcohols in routine use and routes flow to minimize backpressure in service. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Optimized internal geometry minimizes backpressure in service
• Rigid polypropylene body holds its shape under manual filtration pressure
• 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 ahead of HPLC and UPLC injection.

Hydrophobic

• Pump Protection - Acts as a reliable hydrophobic barrier to protect vacuum pumps from corrosive moisture damage and particulate contamination
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, ensuring pure filtrate quality every time
• 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
• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in challenging atmospheric monitoring conditions
• Moisture Barrier - Protects sensitive electronic sensors and instruments from aqueous aerosols while allowing gases to pass freely
