Superior Grade Filters for a Variety of
Biological and Environmental Methods
- Type A/E meets the requirements for suspended solids testing, as described in Standard Methods for the Examination of Water and Wastewater, current edition.
- Reduces filtration costs and premature clogging when filtering difficult-to-filter or highly contaminated solutions.
- Extends filter life and reduces final filter changes with high capacity prefilters.
- Eliminates sample contamination. Binder-free borosilicate glass fiber has no added extractables.
- Filters a wide range of particulate loads and viscous solutions with a selection of filter thicknesses from which to choose.
- Filters with binder offer excellent wet strength for easy handling and filter integrity.

Applications
Used in a variety of sample clean-up, 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.
- 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).
