Micro-glass fiber filters offer high efficiency, submicron particle retention combined with high
permeability and high
dust holding capacity. Micro-glass filters are made of high-purity borosilicate glass microfibers that are biologically inert and resistant to most
solvents and reagents with the exception of hydrofluoric acid and highly concentrated alkali solutions. Binder-free grades are temperature resistant to about 500℃
Micro-glass fiber filters are mainly used in applications such as air or water monitoring and can
be used as pre-filters
for membranes.
GF-A
GF-B
Highly efficient for general laboratory filtration Clarification of buffer and reagent solutions Corresponds to many international standards
for air and water pollution monitoring Foodstuff analysis, filtration of algae,
bacteria cultures, proteins
Filtration of suspended solids Waste water analysis Pre-filters for membranes Suitable for filtration of large volumes
GF-C
GF-D
Standard filter for the clarification and
monitoring of waste and water, scintillation
counting on the filter, cell harvesting,
hydrocarbon analysis where cellulose fibers
are a inconvenience
Universal membrane pre-filter material
GF-F
Higher efficiency in particle retention for
smaller particles than other glass fiber grades Clarification of protein solutions Filtration of liquids prior to HPLC
