Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - 4929

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Chemically inert PTFE resists attack from the harshest process chemistries while delivering sterilizing-grade liquid retention at sub-micron pore sizes and combines aqueous wetting with broad solvent resistance. The PP housing prevents sample bypass under rated operating pressure while routing flow to minimize backpressure in service and holds extractables low for sensitive analyses. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Absolute pore size rating gives consistent results across protocols
• Filters aggressive organic solvents without swelling or breakdown
• Low extractables keep the chromatographic background clean
• Surface-treated for direct aqueous wetting without alcohol pre-wetting

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Medical-grade polypropylene with broad chemical compatibility
• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
