Glass Microfiber Filter, Grade GF 9, With Inorganic Binder, Plain Discs, 90 mm Diameter, 100 pcs/pack
Article no.: GF9090
Glass microfiber filters allow a fast filtration with simultaneous high particle retention and good loading capacity.
*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).
Glass microfiber filters are mainly used in applications such as air or water monitoring. Our filters with binder resin have superior wet strength and are excellent for qualitative analysis and prefiltration, especially for heavily contaminated liquids. They are widely used for clarification of aqueous solutions.
Standard Features
Made of 100% borosilicate glass fibres with inorganic binders
Extremely low metal content
Chemical stability: It keeps all its properties in contact with acid solutions (except hydrofluoric acid) and basic solutions at moderate concentrations
High flow speed and high permeability to air
Good stability at high temperatures up to 500°C
Applications
+ Measurement of emission, monitoring of the efficiency of filtration and dedusting, monitoring the combustion air of power plants and of the steel and iron industry
+ Gravimetric measurement of dust release in workplace and production processes
+ Measurement of the proportion of dust particles in technical gases
+ GF9 can be used as membrane pre-filter, it offers the same performance as the formerly used grade GF 92
