Glass Fiber Filter

Recommended filters for controlling both air and water pollution and as a pre-filter for Membrane
Product Description
GREEN MALL® Glass fiber filters are manufactured from 100% borosilicate glass (imported from Germany). 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.
Glass Fiber Filter can help you choose the right application.
Cross Reference
Whatman GF/A GF/B GF/C GF/D GF/F 934-AH GF 6 GF 8 GF 9 GF 10
Made of borosilicate glass fiber without binders or with binder.
Stability at high temperatures: It keeps its properties up to 500 ºC and 180 ºC for Grade GF10.
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.
Two types of glass fiber filters are available:
Binder free glass fiber:Grade GF A, Grade GF B, Grade GF C, Grade GF D, Grade GF F, Grade GF H
Binder glass fiber: Grade GF 6, Grade GF 8,Grade GF 9,Grade GF 10
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
Grade GF 6
Suitable for very fine particles
Removing protein from difficult-to-filter beers
Determination of filterable substances and the residue on ignition (dry weight)
