Acro Disc Syringe Filters w/ PTFE Membrane - 0.2um, 25mm, 50/Pk
Pall SKU: 4225TC

Pall Acrodisc PTFE Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 4225TC

Pall applies its proprietary membrane manufacturing capabilities, integrating specialized media into the Acrodisc housing geometry. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size and suits gas, vent, and solvent-stream filtration. The PP housing keeps the fluid path low in extractable contamination while routing flow to minimize backpressure in service and holds a reliable seal against the membrane edge. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Filters aggressive organic solvents without swelling or breakdown
• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Absolute pore size rating gives consistent results across protocols
• Low extractables keep the chromatographic background clean

Housing Specifications

• Optimized internal geometry minimizes backpressure in service
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses
• Tough polypropylene body tolerates repeated handling at the bench

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 ahead of HPLC and UPLC injection.
