Anotop Plus 10mm Syringe Filter w/GMF PreFilter, 0.1um, 50 Pk
Whatman SKU: 6809-3012

Whatman Anotop Aluminum Oxide Syringe Filters, 0.1 µm, 10 mm, 50/Pk - 6809-3012

Whatman's Anotop line separates by physical particle dimension alone, a capability rooted in ceramic media chemistry rather than the organic polymer chemistries used in most other membrane technologies. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. The alumina membrane achieves bacterial retention at the rated pore size and pulls liquid the membrane's full depth at once. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane and stands firm against aqueous acids, bases, and alcohols during regular handling. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Low intrinsic autofluorescence limits background signal in fluorescence work
• Membrane surface turns optically transparent once wetted with liquid
• Uniform capillary pore array gives high pore density without lateral crossover
• Inorganic ceramic structure resists solvent swelling common to polymer membrane materials
• Chemical stability in aqueous solutions spans a pH 3 to 9 range

Housing Characteristics

• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Thermal-bonded construction keeps adhesives out of the fluid path
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods. Ask our customer support technicians for chemical compatibility guidance on your specific filtration application.
