Description

Combines high loading capacity with fine particle retention. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/A are ideal for gravimetric determination of airborne particulates, stack sampling and absorption methods of air pollution monitoring.

Whatman glass microfiber filters without binder feature low resistance to fluid flow and high particle-loading capacity. These filters can be used at temperatures up to 500°C. The fine capillary structure of glass fiber filters can absorb large quantities of water, enabling spot tests and liquid scintillation counting methods.

Glass microfiber filters are mainly used in applications such as air or water monitoring and can be used as pre-filters for membranes.

  • High flow rate
  • Good loading capacity
  • Water pollution effluent monitoring
  • Filtering water, algae, bacterial cultures
  • Foodstuff analyses
  • Protein filtration
  • Radioimmunoassay of weak β-emitters
