Anotop 10mm Sterile Syringe Filters, 0.2um, 50 Pk
Whatman SKU: 6809-1122

Whatman Anotop Aluminum Oxide Syringe Filters, 0.2 µm, 10 mm, 50/Pk - 6809-1122

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 delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. The alumina membrane tolerates high temperatures and broad solvent ranges and pulls liquid the membrane's full depth at once. Polypropylene construction resists chemical degradation from routine sample matrices while shedding virtually no extractable material into the sample and sustains efficient flow on viscous samples. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Mineral oxide chemistry gives proteins little to adsorb onto
• Absolute pore-size rating holds consistent across every protocol
• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Membrane surface turns optically transparent once wetted with liquid
• Extractable content stays minimal without interfering with downstream detection

Housing Characteristics

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Stable across the full aqueous pH range in routine sample work
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Each housing is factory-sterilized and sealed individually to maintain sterility through the supply chain.

Upstream clarification pays for itself by keeping your columns clear and your analytical day on schedule. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.
