Anotop Plus 25mm Syringe Filter w/GMF PreFilter, 0.1um, 50 Pk
Whatman SKU: 6809-4012

Whatman Anotop Aluminum Oxide Syringe Filters, 0.1 µm, 25 mm, 50/Pk - 6809-4012

Whatman's expertise in cellulose, glass fiber, and polymeric membrane production guides material selection and quality control. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Aluminum oxide delivers sterile-grade retention at the rated sub-micron pore size while preserving dilute proteins and analytes in the filtrate and stays compatible with aqueous samples, alcohols, and organic solvents. The PP housing keeps the fluid path low in extractable contamination while sustaining efficient flow on viscous samples and holds a reliable seal against the membrane edge. 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 sample recovery
• Rigid inorganic structure withstands high temperatures with minimal extractables
• Uniform capillary pore array gives high flow and high pore density
• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Absolute pore-size rating gives consistent retention across protocols

Housing Specifications

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

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data before each HPLC, UPLC, and dissolution run.
