glass fiber filters

Features Of Product

• 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℃

Applications

• Micro-glass fiber filters are mainly used in applications such as air or water monitoring and can be used as pre-filters
  for membranes.

          Grade

GF-B	GF-A
Filtration of suspended solids Waste water analysis Pre-filters for membranes Suitable for filtration of large volumes	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
GF-D	GF-C
Universal membrane pre-filter material	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
	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
