Glass Fiber Filter CA-GFF

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)
• Analysis of aggressive media

Grade GF 8 and Grade GF 9

• Used in the filtration of coarse particles
• Determination of PCB, DDE, DDT, furans and dioxins in the air
• Environmental analysis
• Membrane pre-filter

Grade GF 10

• Used in the filtration of coarse particles
• Weighing aid for infrared weighing
• A roll filter in automatic air filtration units
