Pall SKU: 4553

Pall Acrodisc PTFE Syringe Filters, 0.45 µm, 13 mm, 300/Pk - 4553

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PTFE stays chemically inert against aggressive solvents, strong acids, and alkalis in service while repelling water and passing gases and solvents freely and handles concentrated acids and bases. The polypropylene housing routes flow to minimize backpressure in service while contributing minimal extractables to the filtrate and holds a reliable seal against the membrane edge. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Low extractables keep the chromatographic background clean
• Absolute pore size rating gives consistent results across protocols
• Chemically inert against aggressive solvents, strong acids, and alkalis

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Medical-grade polypropylene with broad chemical compatibility

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.
