Glass Fiber Filters
Superior grade glass fiber filters for a variety of applications
  • Type A/E meets the requirements for suspended solids testing, as described in Standard Methods for the Examination of Water and Wastewater, current edition.
  • Reduce filtration costs and premature clogging when filtering difficult-to-filter or highly contaminated solutions.
  • Extend filter life and make fewer final filter changes with high capacity prefilters.
  • Eliminate sample contamination. Binder-free borosilicate glass fiber has no added extractables.
  • Filter a wide range of particulate loads and viscous solutions with a selection of filter thicknesses from which to choose.
  • Excellent wet strength for easy handling and filter integrity.
Used in a variety of sample cleanup, prefiltration, and analytical testing applications. Choose between binder-free borosilicate glass for complete purity or glass fiber with acrylic binder for added strength.

Type A/E Glass Fiber

  • For testing dissolved and suspended solids in wastewater and gravimetric analysis of air pollutants.
  • High flow rates, wet strength, and dirt (solids) holding capacities.

Type A/B Glass Fiber

  • High dirt-loading capacity with 2.5 times thicker glass than Type A/C.
  • Manufactured of the highest quality borosilicate glass microfibers.

Type A/C Glass Fiber

  • For testing dissolved and suspended solids in wastewater.
  • 254 µm (10 mils) thickness is useful for cell harvesting applications.
  • Purity eliminates risk of unwanted contaminants leaching into the filtrate.

Type A/D Glass Fiber

  • Excellent prefilters for solutions with a heavy load of large-sized particulate that must be removed.
  • Large nominal pore size (3 µm) reduces membrane clogging.

Extra Thick Glass Fiber

  • Preferred for prefiltration of viscous biological solutions.
  • High particulate-holding capacity makes discs efficient depth filters and allows for filtration of large volumes of solutions.

Metrigard™ Glass Fiber

  • Useful for prolonging membrane filter life in liquid systems that contain substantial amounts of particulate matter.
