Anotop 10mm Sterile Syringe Filters, 0.02 um, 50 Pk
Whatman SKU: 6809-1102

Whatman Anotop Aluminum Oxide Syringe Filters, 0.02 µm, 10 mm, 50/Pk - 6809-1102

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. Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The nanoporous Anotop surface slows early bacterial colonization compared to a smooth surface and stays compatible with aqueous samples, alcohols, and organic solvents. Polypropylene housing is factory-sterilized and packaged to preserve that state until use and leaves no seam for sample to bypass the membrane. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Mineral oxide chemistry gives proteins little to adsorb onto
• Inorganic ceramic structure resists solvent swelling common to polymer membrane materials
• Chemical stability in aqueous solutions spans a pH 3 to 9 range
• Extractable content stays minimal without interfering with downstream detection
• Low intrinsic autofluorescence limits background signal in fluorescence work

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion.
• Minimal extractable release from the housing supports sensitive analytical work downstream

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows. Bulk pricing kicks in on larger filtration orders, so ask the Tisch Scientific team for a quote.

Hydrophilic

• Membrane Protein Research - Filters detergent-solubilized protein preparations to remove insoluble aggregates before crystallography and cryo-EM.
• Drug Nanoparticle QC - Removes oversized aggregates from nanoparticle drug carriers before size and zeta potential analysis for formulation release.
• Nucleic Acid Clarification - Removes particulates from plasmid and oligonucleotide preparations ahead of gel electrophoresis and UV quantitation.
• Quantum Dot Preparation - Removes oversized aggregates from quantum dot suspensions ahead of photoluminescence and fluorescence spectroscopy.
• Virus Filtration - Separate viruses and bacteriophages effectively, utilizing precise pore size exclusion for accurate biological separations.
• Low-Bleed IC Sampling - Filter samples for ion chromatography confidently, as the alumina membrane leaches minimal anions into the analyte stream.
