PES Syringe Filters, 0.22 um, 4mm, Luer-Lok/Luer Slip, Nonsterile, 200/Pk
Tisch SKU: SF17512

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.22 µm, 4 mm, 200/Pk - SF17512

Tisch Scientific welcomes bulk and blanket orders with volume discounts. Under hand pressure from the syringe, the membrane captures particulates as the sample passes through. Low-binding PES achieves sterile-grade retention with high recovery while accepting water-based reagents without preconditioning and preserves dilute proteins and analytes in the filtrate. The polypropylene housing routes flow to minimize backpressure in service and prevents sample bypass under rated operating pressure. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

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

Housing Specifications

• Tough polypropylene body tolerates repeated handling at the bench
• Low extractable contribution protects sensitive downstream analyses
• Rigid polypropylene body holds its shape under manual filtration pressure
• Medical-grade polypropylene with broad chemical compatibility

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.
