Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 200/Pk - 4927

Pall Corporation brings decades of fluid management expertise to laboratory-scale filtration challenges. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Chemically inert PTFE resists attack from the harshest process chemistries and combines aqueous wetting with broad solvent resistance. The polypropylene housing contributes minimal extractables to the filtrate while resisting degradation from routine sample matrices 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

• Surface-treated for direct aqueous wetting without alcohol pre-wetting
• Stable across a wide operating temperature range for demanding methods
• Absolute pore size rating gives consistent results across protocols
• Sterilizing-grade liquid retention at sub-micron pore sizes
• Low extractables keep the chromatographic background clean

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Resists stress cracking from aqueous salt and buffer solutions
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
