Glass Fiber Filter



Glass fiber filters are manufactured from 100% borosilicate glass. These depth filters combine fast flow rate with high loading capacity and retention of fine particulates. The small diameter fibers give micro glass media superior efficiency and dirt holding as compared to cellulose and synthetic media.




•Made of borosilicate glass fiber without binders or with binder.

•Usable as Pre-filter for membranes to prevent the membranes from silting up.

•Large surface area provides an outstanding retention capacity.

•High flow speed and high permeability to air.

•Reduce filtration costs and premature clogging when filtering difficult-to-filter or highly contaminated solutions.

•Excellent wet strength for easy handling and filter integrity.


Product Specification/Models


Grade GF A •Highly efficient for general laboratory filtration •Clarification of buffer and reagent solutions •Corresponds to many international standards for air and water pollution monitoring


Grade GF B •Thicker than GF A with higher wet strength and significantly increased loading capacity , Suitable for filtration of large volumes •Pre-filter for membranes •Filtration of suspended solids in water/waste water analysis


Grade GF C •The standard filter in many parts of the world for the collection of suspended solids in potable water and natural and industrial wastes •Widely used for cell harvesting, liquid scintillation counting and binding assays where more loading capacity is required


Grade GF D •Universal membrane pre-filter material •Filtration in food industry


Grade GF F •GF F is the material upon which the EPA Method TCLP 1311 for Toxicity •Use for filtering extremely fine precipitates such as protein, nucleic acids, or serum precipitates Grade GF H •Suitable for suspended solid analysis •Cell harvesting •Air pollution control
