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. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. The alumina matrix presents a mineral oxide surface, not an organic polymer while becoming transparent in liquid after wetting and pulls liquid the membrane's full depth at once. The polypropylene housing keeps the sample chemically unaltered across the pass while maintaining a low-dead-volume internal flow path and holds its seal true run after run. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.
Membrane Characteristics
- Low intrinsic autofluorescence limits background signal in fluorescence work
- Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
- Chemical stability in aqueous solutions spans a pH 3 to 9 range
- Anodized alumina matrix contains no monomers, plasticizers, adhesives, or wetting agents
- Absolute pore-size rating holds consistent across every protocol
Housing Characteristics
- Polypropylene housing withstands rated backpressure from dense sample matrices without deformation.
- Standardized luer connection geometry provides secure engagement with standard syringe tips
- 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
Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.
