Glass Microfiber Filter, Grade GF 52, W/O Binder, Plain Discs, 90 mm Diameter, 100 pcs/pack
Article no.: GF52090
Hahnemühle glass microfiber filters without binder feature low resistance to fluid flow and high particle-loading capacity. 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. Glass fibre filters absorb the finest particles down to 1 μm from liquids, in air, gases and even aerosols with 0.3 - 0.5 μm are separated.
*Weight consistency: No relevant changes in weight due to variations in the ambient humidity.
*Limited bending resistance: Brushing against other surfaces may cause the loss of fibres (keep the filters in their original box until their use).
