Pall Acrodisc Nylon Syringe Filters, 0.45 µm, 13 mm - 4551TC

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. The nylon matrix handles alcohols and aliphatic and aromatic solvents and holds consistent retention across mixed-phase samples. The PP housing prevents sample bypass under rated operating pressure while resisting degradation from routine sample matrices and routes flow to minimize backpressure in service. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Alkaline-resistant across a broad range of aqueous buffers
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• High tensile strength for stability under elevated differential pressures
• Stable across the pH 3 to 12 operating range
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving across the buffers and reagents your methods rely on. Review our Chemical Compatibility Chart, or ask technical service to confirm chemical compatibility for your specific application.
