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 550°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.
Ready-to-use (RTU) formats available for Total Suspended Solid (TSS), Total Dissolved Solids (TDS) and Total Suspended Volatiles (VSS).
