Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.22 µm, 33 mm, 100/Pk - SF14508

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. 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 wetting on contact with aqueous buffers and preserves dilute proteins and analytes in the filtrate. MBS construction holds up to aqueous samples and buffers in routine prep while taking hand pressure without cracking and stays dimensionally stable through the filtration run. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Low protein binding preserves dilute analytes for maximum recovery
• Stable across the full pH 1 to 14 operating range
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Absolute pore size rating gives consistent results across protocols

Housing Specifications

• Optically clear MBS housing keeps the sample visible end to end
• Housing-to-membrane seal keeps the sample from bypassing the membrane
• Dimensionally stable body maintains housing integrity under hand pressure
• Hard methacrylate surface resists scuffing through repeated handling

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
