Anotop 25mm Sterile Syringe Filters, 0.1um, 50 Pk
Whatman SKU: 6809-2112

Whatman Anotop Aluminum Oxide Syringe Filters, 0.1 µm, 25 mm, 50/Pk - 6809-2112

Whatman's brand recognition and documented performance history support specification in standardized analytical methods. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Aluminum oxide keeps protein binding low to maximize sample recovery and sustains high flow with a narrow pore distribution. Polypropylene construction maintains a low-dead-volume internal flow path while contributing minimal extractables to the filtrate and resists aqueous acids, bases, and alcohols. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

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

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service
• Low extractable contribution protects sensitive downstream analyses

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.
