Anotop 25mm Syringe Filter, 0.02 um, 50 Pk
Whatman SKU: 6809-2002

Whatman Anotop Aluminum Oxide Syringe Filters, 0.02 µm, 25 mm, 50/Pk - 6809-2002

Whatman applies over a century of filtration media expertise, manufacturing under the quality standards that established its products as global laboratory references. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. High-porosity aluminum oxide sustains high flow with a narrow pore distribution and keeps protein binding low for high analyte recovery. The polypropylene housing holds a reliable seal against the membrane edge while maintaining a low-dead-volume internal flow path and stays inert across common laboratory solvents. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Absolute pore-size rating gives consistent retention across protocols
• Naturally hydrophilic ceramic surface wets without pre-wetting in aqueous samples
• Chemically inert alumina compatible with aqueous solutions, alcohols, and organic solvents
• Low protein binding preserves dilute analytes for maximum sample recovery
• Uniform capillary pore array gives high flow and high pore density

Housing Specifications

• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Low extractable contribution protects sensitive downstream analyses

Filtering particulates upstream protects the column investment your methods depend on. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
