Anotop Plus 25mm Sterile Syringe Filter w/GMF PreFilter, 0.02 um, 50 Pk
Whatman SKU: 6809-4102

Whatman Anotop Aluminum Oxide Syringe Filters, 0.02 µm, 25 mm, 50/Pk - 6809-4102

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Aluminum oxide keeps protein binding low to maximize sample recovery while accepting water-based reagents without preconditioning and tolerates high temperatures and broad solvent ranges. The PP housing prevents sample bypass under rated operating pressure and keeps the fluid path low in extractable contamination. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Low protein binding preserves dilute analytes for maximum sample recovery
• Chemically inert alumina compatible with aqueous solutions, alcohols, and organic solvents
• Rigid inorganic structure withstands high temperatures with minimal extractables
• Uniform capillary pore array gives high flow and high pore density

Housing Specifications

• Low extractable contribution protects sensitive downstream analyses
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible from sample preparation through final injection.
