Whatman glass microfibre filters are binder free and feature low resistance to fluid flow and a high particle-loading capacity. These filters can be used at temperatures up to 500°C and can absorb large quantities of water making them suitable for spot tests and liquid scintillation counting methods.

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

Grade GF/A microfibre filters are used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, filtration of water, algae and bacteria cultures, foodstuff analyses, protein filtration, and radioimmunoassay of weak ß emitters. Recommended for gravimetric determination of airborne particulates, stack sampling, and absorption methods of air pollution monitoring.

Particle retention 1.6µm.
