Acro Disc One Syringe Filters w/ wwPTFE Membrane - GxF/0.2um, 25mm, 1000/Pk
Pall SKU: AP-4915

Pall Acrodisc Water-Wettable PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4915

Pall applies its proprietary membrane manufacturing capabilities, integrating specialized media into the Acrodisc housing geometry. Across analytical workflows, the syringe filter is where particulates leave the sample stream. Water-wettable PTFE stays chemically inert against aggressive solvents and acids in service while providing sterile-grade filtration at sub-micron pore sizes and handles both aqueous buffers and organic solvents. Polypropylene construction holds extractable contribution low for sensitive analyses while staying inert across common laboratory solvents 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

• Absolute pore-size rating gives consistent retention across protocols
• Chemically inert to aggressive organic solvents, strong acids, and alkalis
• Water-wettable surface wets directly with both aqueous and organic samples
• Low protein binding preserves dilute analytes for maximum recovery
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Resists stress cracking from aqueous salt and buffer solutions
• Thermal-bonded construction keeps adhesives out of the fluid path
• Optimized internal geometry minimizes backpressure in service

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible so your filtrate reaches the column clean.
