These glass microfibre filters made from borosilicate glass are used for filtration of coarse particles. They offer faster filtration and a higher air flow rate compared to the similar grade GF 9 filters.

• Inorganic binder for increased strength
• Fast filtration speed
• Can be used as a prefilter for dense samples
• Function as air pollution filters for detecting furans, PCB, and other chemicals

With the added strength of an inorganic binder, grade GF 8 glass microfibre filters serve as air pollution filters by retaining a range of heavy particles found in vapor samples.
