Anotop 10mm Sterile Syringe Filters, 0.1um, 50 Pk
Whatman SKU: 6809-1112

Whatman Anotop Aluminum Oxide Syringe Filters, 0.1 µm, 10 mm, 50/Pk - 6809-1112

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. Aluminum oxide's straight channels pull samples by capillary action while delivering sterile-grade retention at sub-micron pore sizes and handles aqueous and solvent samples cleanly. The polypropylene housing presses snugly against the membrane during the pass and is supplied pre-sterilized in individual packaging for sterile sample preparation. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Membrane Characteristics

• Uniform capillary pore array gives high pore density without lateral crossover
• Anodized alumina matrix contains no monomers, plasticizers, adhesives, or wetting agents
• Extractable content stays minimal without interfering with downstream detection
• Chemical stability in aqueous solutions spans a pH 3 to 9 range
• Inorganic ceramic structure resists solvent swelling common to polymer membrane materials

Housing Characteristics

• Housing rated for reliable filtration under syringe-applied backpressure at its maximum operating pressure.
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Resists stress cracking from aqueous salt and buffer solutions
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on so your retention times and peak shapes stay consistent.
