Grade 934-AH: 1.5 µm
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 smoothsurface, 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 ofbacterial 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 pollutionmonitoring.
