Anotop 10mm Syringe Filter, 0.1um, 50 Pk
Whatman SKU: 6809-1012

Whatman Anotop Aluminum Oxide Syringe Filters, 0.1 µm, 10 mm, 50/Pk - 6809-1012

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. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. Anotop's Anopore membrane becomes transparent in liquid after wetting and keeps that hydrophilic chemistry intact across every filtration cycle. Polypropylene construction resists chemical degradation from routine sample matrices and leaves no seam for sample to bypass the membrane. When sterile or particle-free preparation matters at the bench, sterilizing-grade retention delivers it in a single pass.

Technical Specifications

• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Absolute pore-size rating gives consistent retention across protocols
• Anodized alumina matrix contains no monomers, plasticizers, adhesives, or wetting agents, removing a source of trace organic contamination
• Minimal extractable content supports HPLC mobile phase filtration without interfering with downstream detection
• Anodized alumina structure stays chemically stable in aqueous solutions across a pH 3 to pH 9 range

Housing Specifications

• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Optimized internal geometry minimizes backpressure in service

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Low Background Specs - Prepare samples for spectrophotometry, ensuring extremely low optical background for the most sensitive analytical readings.
• HPLC Solvent Filtration - Filter chromatography mobile phases and solvents reliably, resisting degradation from aggressive organic reagents.
• Epifluorescence Counting - Counts bacteria and viruses precisely in water samples, using the low-autofluorescence surface for microscopy.
• Low-Bleed IC Sampling - Filter samples for ion chromatography confidently, as the alumina membrane leaches minimal anions into the analyte stream.
• Electron Microscopy Prep - Image retained particulates directly, using the electron-beam-stable ceramic surface for SEM and TEM sample preparation.
• Polymer Removal - Remove high molecular weight polymers efficiently, utilizing the unique inorganic membrane structure for difficult separations.
