Anotop 10mm Syringe Filter, 0.02 um, 50 Pk
Whatman SKU: 6809-1002

Whatman Anotop Aluminum Oxide Syringe Filters, 0.02 µm, 10 mm, 50/Pk - 6809-1002

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. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. The alumina membrane tolerates high temperatures and broad solvent ranges and provides sterile-grade retention with high recovery. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane while staying inert across common laboratory solvents and sustains efficient flow on viscous samples. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Extractable content stays minimal without interfering with downstream detection
• Low intrinsic autofluorescence limits background signal in fluorescence work
• Chemical stability in aqueous solutions spans a pH 3 to 9 range
• Anodized alumina matrix contains no monomers, plasticizers, adhesives, or wetting agents
• Mineral oxide chemistry gives proteins little to adsorb onto

Housing Characteristics

• Stable across the full aqueous pH range in routine sample work
• Thermal-bonded construction keeps adhesives out of the fluid path
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification clears particulates without slowing your bench routine across the buffers and reagents your day-to-day prep depends on. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.
