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 unique alumina based Anopore® membrane and are supplied in three pore sizes. Glass microfiber prefilter versions are available for difficult-to-filter samples.
 

Anotop 10

Features
  • 10 mm diameter syringe filter
  • Inorganic membrane
  • Capillary pore structure
Benefits
  • Low protein binding
  • Filters sample volume up to 10 mL
  • Low hold-up volume <20 µL ensures maximum
    sample recovery
  • Sterile formats are available for critical applications

Anotop 10 Plus

The Anotop 10 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 heavily particulate loaded samples prior to HPLC
  • Removal of solids prior to UV/Vis analysis

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
  • Liposome extrusion
  • Filtration of solvents for spectroanalysis and analytical sample preparation

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

Anotop IC

Whatman Anotop IC syringe filters are specifically
designed for the preparation of samples for subsequent
ion chromatography and HPLC analysis. These
devices ensure very low levels of anion leaching for
ion chromatography testing.

Features:
  • 10 mm diameter syringe filters
  • 25 mm diameter syringe filters
  • Each batch certified for IC
Benefits:
  • Enhanced consistency of analytical results
  • Extended column life
  • Certified and guaranteed low levels of anion leaching
    for improved results
Applications:
  • Ion chromatography sample preparation
  • HPLC sample preparation
