General description

Whatman® Anotop® 25 Syringe Filter

Anotop syringe filters are a universal solution for numerous filtration applications. Anotop filters can be used with most organic solvents and aqueous materials, and they are suitable for sample volumes up to 100 mL. The distinctive hexagonal housing is manufactured from pigment-free polypropylene to eliminate sample contamination. No wetting agents or adhesives are used in the manufacturing process.

Anotop syringe filters contain the proprietary alumina based Anopore membrane and are supplied in three pore sizes. Glass microfiber prefilter versions are available for difficult-to-filter samples.

Note: Anotop syringe filters contain the proprietary alumina based Anopore membrane.

Features and Benefits:
• 25 mm diameter syringe filter
• Filters sample volume up to 100 mL


• Cold sterilization of growth media
• Phage and virus filtration
• Removal of high molecular weight proteins or polymers
• Liposome extrusion
• Filtration of solvents for spectroanalysis and analytical sample preparation


Suitable for filtration of aqueous or organic solutions.
