Membrane Filter Holders

Whatman offers a choice of holders for use with membrane filters.

Vacuum type glass holders
Produced from borosilicate glass and available with a choice of support screen. Suitable for aqueous and organic solvent filtration. The funnel seal ensures that the sample does not bypass the membrane and that particulates are retained on the surface of the membrane.

The sintered glass support is recommended for filtration and biological analysis. The 304 stainless steel support screen is suitable for use with proteinaceous solutions.

Polyester drain discs
For use with membrane hardware where extra support is needed for improved flow rate and throughput. The polyester drain disc is binder free and has a thickness of 100 µm. It provides a flat surface to eliminate filter tearing or rupturing. It is also used as a separator between membrane layers in serial stack filtration applications. This chemically inert support disc is available in a variety of diameters for use in a range of devices.

Applications
  • General laboratory microfiltration
  • Quality control and sterility testing
  • Removal of particulates from HPLC solvents
  • Tissue culture media filtration
