Acro Disc Syringe Filters w/ Supor Membrane - 5um, 32mm Modified Acrylic Housing, 1000/Pk
Pall SKU: 4662

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 5 µm, 32 mm, 1000/Pk - 4662

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. PES holds consistent absolute retention at the rated pore size and accepts water-based reagents without preconditioning. Polypropylene construction resists chemical degradation from routine sample matrices while preventing sample bypass under rated operating pressure 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

• Absolute pore size rating gives consistent results across protocols
• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Low protein binding preserves dilute analytes for maximum recovery
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Stable across the full aqueous pH range in routine sample work
• Resists aqueous acids, bases, and alcohols in routine sample prep

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification keeps your sample preparation moving from the first sample of the day through the last.
