Acro Disc PSF Syringe Filters w/ PVDF Membrane - GxF/0.2um, 25mm, 1000/Pk
Pall SKU: AP-4794

Pall Acrodisc PVDF Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4794

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. The hydrophilic PVDF membrane keeps analyte adsorption low for clean recovery and holds up to alcohols and mild hydrocarbon solvents. The PP housing stays inert across common laboratory solvents and buffers in routine use and contributes minimal extractables to the filtrate. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Sterilizing-grade retention at sub-micron pore sizes
• Low extractables preserve a clean chromatographic baseline
• Hydrophilic surface wets aqueous and HPLC samples without pre-wetting
• Mechanically durable membrane holds integrity under filtration pressure
• Ultra-low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Rigid polypropylene body holds its shape under manual filtration pressure
• Low extractable contribution protects sensitive downstream analyses
• Thermal-bonded construction keeps adhesives out of the fluid path

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
