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.

Qualitative Paper Filters
P1 Grade - Medium flow rate and retention
  • Air pollution testing where atmospheric dust is collected and the stain-intensity measured photometrically.
  • Testing for aluminum phosphate, barium, carbonate, lead chromate, and beryllium hydroxide.
  • Typically used for clarifying liquids and separations for precipitates such as lead sulfate and calcium oxalate.
P4 Grade - Fast flow rate, coarse surface
  • Air monitoring, gas filtration, ferric and magnesium hydroxides, and insolubles.
  • Routine cleanup of biological fluids or organic extracts during analysis.
P5 Grade - Slow flow rate for fine retention
  • Water analysis, biological products, fine precipitates, used in Buchner funnels.
Quantitative Paper Filters
PA40 Grade - Medium flow rate
  • Good retention for filtering trace elements, silver chromate, lead sulfate, zinc, and ammonium hydroxides.
  • Gravimetric analysis for cements, clays, iron, and steel products.
  • Primary filter for separating solid matter from aqueous extracts in general soil analysis.
PA41 Grade - Fast flow rate, coarse surface
  • Air analysis, aluminum and zirconium hydroxides, cobalt sulfide, and gelatinous particles.
PA42 Grade - Slow flow rate for fine retention
  • Retention of very fine particles, barium and lead sulfates, stannic and nickel sulfide, calcium oxalate, and calcium fluoride.
  • Analytical applications.
  • Gravimetric analysis.
