Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 25 mm, 200/Pk - AP-4219

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Chemically inert PTFE resists attack from the harshest process chemistries while filtering aggressive organic solvents without breakdown and blocks aqueous ingress in vent applications. Polypropylene construction holds extractable contribution low for sensitive analyses while sustaining efficient flow on viscous samples and maintains housing integrity through the filtration run. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Rigid polypropylene body holds its shape under manual filtration pressure
• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Reliable solvent prefiltration clears particulates from your organic samples so your downstream method starts with a clean sample.
