Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4791

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. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis in service and repels water while passing gases and solvents freely. The PP housing stays inert across common laboratory solvents and buffers in routine use while sustaining efficient flow on viscous samples and maintains housing integrity through the filtration run. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Stable across a wide operating temperature range for demanding methods
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Filters aggressive organic solvents without swelling or breakdown
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Plasticizer-free polyolefin construction keeps the fluid path clean

Clarifying organic mobile phases before injection protects your chromatography while standing up to the solvent. Reliable solvent prefiltration clears particulates from your organic samples ahead of HPLC and UPLC injection. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
