Anotop Plus 10mm Syringe Filter w/GMF PreFilter, 0.02 um, 50 Pk
Whatman SKU: 6809-3002

Whatman Anotop Aluminum Oxide Syringe Filters, 0.02 µm, 10 mm, 50/Pk - 6809-3002

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. Low-binding aluminum oxide provides sterile-grade retention with high recovery and keep each molecule's channel-wall contact brief. The PP housing sustains efficient flow on viscous samples and sheds virtually no extractable material into the sample. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Membrane surface turns optically transparent once wetted with liquid
• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Inorganic ceramic structure resists solvent swelling common to polymer membrane materials
• Anodized alumina matrix contains no monomers, plasticizers, adhesives, or wetting agents
• Uniform capillary pore array gives high pore density without lateral crossover

Housing Characteristics

• Minimal extractable release from the housing supports sensitive analytical work downstream
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Optimized internal geometry minimizes backpressure in service

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.

• HPLC Solvent Filtration - Filter chromatography mobile phases and solvents reliably, resisting degradation from aggressive organic reagents.
• Flow Cytometry Prep - Removes residual debris and aggregates from cell suspension buffers before immunophenotyping and bead-based multiplex assays.
• Cold Sterilization - Sterilize heat-sensitive additives safely, using 0.02 µm pores to remove bacteria without degrading critical components.
• Single-Particle Analysis - Concentrates nanoparticles from dilute suspensions for tunable resistive pulse sensing and nanoparticle tracking.
• Clinical Biomarker Prep - Removes debris from plasma and serum aliquots for protein and small-molecule biomarker profiling by mass spectrometry.
• Diagnostic Assay Input - Delivers ultrapure aqueous filtrates from clinical matrices for enzymatic and colorimetric point-of-care diagnostic assays.
