GE Whatman* Anotop* 25 Syringe Filters

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.

Anotop 25 Features:
• 25 mm diameter syringe filter
• Filters sample volume up to 100 ml
Applications:
• Cold sterilization of growth media
• Phage and virus filtration
• Removal of high molecular weight proteins or polymers

Anotop 25 Plus:
The Anotop 25 Plus syringe filter offers the added benefit of an integral glass microfiber prefilter. This unit is designed to enable difficult and hard-to-filter solutions to be filtered without adversely affecting the filtration efficiency of the final membrane. This can eliminate the need for sample clean-up or expensive and time-consuming sequential filtration.
Applications:
• Filtration of tissue culture media
• Clean-up of difficult samples
• Filtration of colloidal material
• Removal of mycoplasma
• HPLC sample preparation
• Biological sample preparation
