Anotop 25mm Sterile Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6809-2122

Whatman Anotop Aluminum Oxide Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6809-2122

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Chemically inert aluminum oxide handles aqueous and solvent samples cleanly and presents a high-density honeycomb pore structure. The PP housing stays inert across common laboratory solvents and buffers while routing flow to minimize backpressure in service 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

• Absolute pore-size rating gives consistent retention across protocols
• Uniform capillary pore array gives high flow and high pore density
• Low protein binding preserves dilute analytes for maximum sample recovery
• Chemically inert alumina compatible with aqueous solutions, alcohols, and organic solvents
• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep

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.
