General description

The fine particle retention of this popular grade is superior for its high retention efficiency at high flow rates and its high loading capacity. This is a smooth surface, high-retention borosilicate glass microfiber filter which withstands temperatures over 500°C.

Used for determining total suspended solids in water, removal of turbidity, and filtration of bacterial cultures. Grade 934-AH is used for a wide range of laboratory applications. It is recommended for water pollution monitoring, cell harvesting, liquid scintillation counting, and air pollution monitoring.

Features and benefits:
  • Excellent fine particle retention: allows high particle retention efficiency when filtering large volumes
  • Binder-free, high-grade borosilicate glass microfiber: enables use with temperatures up to 550ºC
  • Available in a wide range of sizes: in circle and sheet formats
  • High loading capacity: capable of processing very turbid streams
  • Low fiber shedding: improves quality assurance of test results

Applications:
  • Water pollution monitoring
  • Air pollution monitoring
  • Cell harvesting
  • Liquid scintillation counting
