Acro Disc One Syringe Filters w/ wwPTFE Membrane - 0.2um, 25mm, 1000/Pk
Pall SKU: AP-4912

Pall Acrodisc Water-Wettable PTFE Syringe Filters, 0.2 µm, 25 mm, 1000/Pk - AP-4912

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. Syringe filters mount on a syringe to clarify a sample in a single manual pass. Water-wettable PTFE delivers sterile-grade retention at the rated sub-micron pore size while filtering aqueous and organic samples in one membrane and wets directly with aqueous and organic samples. Polypropylene construction resists chemical degradation from routine sample matrices while contributing minimal extractables to the filtrate and routes flow to minimize backpressure in service. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Sterile-grade retention at sub-micron pore sizes
• Low protein binding preserves dilute analytes for maximum recovery
• Water-wettable surface wets directly with both aqueous and organic samples
• Universal compatibility across aqueous buffers and organic solvents
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Resists stress cracking from aqueous salt and buffer solutions
• Tough polypropylene body tolerates repeated handling at the bench

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
