More-Details:
934-AH Glass Microfiber filters are suitable for suspended solids analysis. These filters also permit rapid passage of very large sample volumes without blockage for the collection of suspended solids in potable, natural, and industrial waters. Specified in standard methods* for determining total suspended solids in water, 934-AH Glass Microfiber Filters are excellent for the removal of turbidity and filtration of bacterial cultures. The fine particle retention of this popular grade is superior to any cellulose filter of similar rating and is capable of high retention efficiency at high flow rates.
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.
