GE’s Whatman brand Grade GF/B is a fine particle filter with high wet-strength and high loading capacity. GF/B filters are particularly useful for liquid clarification and liquid scintillation counting.

  • High wet-strength and loading capacity
  • Nominal particle retention of 1.0 µm
  • Medium to fast filtration speed
  • Appropriate for liquid clarification and/or liquid scintillation

GE offers a wide range of glass microfiber filters to support your analyses. See the Whatman range of glass, binder-free filters to find the thickness and particle retention for your application. Liquid scintillation counting requires a fine particle filter, preferably with a high loading capacity. Grade GF/B filters from GE Healthcare’s Life Sciences business are ideal for this and similar applications such as waste characterization and liquid clarification for suspended solids analysis.
