Acro Disc PF Syringe Filters w/ Supor Membrane, Sterile - 0.8/0.2um, 25mm, 50/Pk
Pall SKU: 4187

Pall Acrodisc Polyethersulfone (PES) Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 4187

Pall Corporation combines proprietary membrane technology with a housing platform validated for both manual and automated filtration workflows. Across analytical workflows, the syringe filter is where particulates leave the sample stream. The PES membrane draws aqueous buffers through without pre-wetting while providing sterile-grade retention at sub-micron pore sizes and tolerates aqueous buffers, aliphatic alcohols, and glycols. The PP housing keeps the fluid path low in extractable contamination and maintains housing integrity through the filtration run. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High flow rate with low extractable background for clean preparations
• Stable across the full pH 1 to 14 operating range
• Low protein binding preserves dilute analytes for maximum recovery
• Sterile-grade retention at sub-micron pore sizes

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility

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.
