Anotop 25mm Syringe Filter, 0.2um, 50 Pk
Whatman SKU: 6809-2022

Whatman Anotop Aluminum Oxide Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6809-2022

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The alumina membrane achieves bacterial retention at the rated pore size while tolerating high temperatures and broad solvent ranges and holds protein adsorption low across the run. Polypropylene construction maintains housing integrity through the filtration run while staying inert across common laboratory solvents and sustains efficient flow on viscous samples. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

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

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Optimized internal geometry minimizes backpressure in service
• Thermal-bonded construction keeps adhesives out of the fluid path
• Medical-grade polypropylene with broad chemical compatibility

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data so column life and baseline stability stay predictable.
