  • Description

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.
  • 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 reduces membrane clogging.

Extra Thick Glass Fiber With Binder

  • 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 With Binder

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

TCLP Glass Fiber

  • Designed to meet requirements for use in U.S. EPA SW-846 Method 1311: Toxic Characteristics Leaching Procedure (TCLP).
