Glass Microfiber Filter Paper - 1310-0250 - Grade 131, 2.50cm 15cm zirconium and aluminum hydroxides

zirconium and aluminum hydroxides

Grade 54 is also used in air pollution testing to determine gaseous compounds

This grade offers better filtration speed and a higher loading capacity than an analytical filter paper of similar particle retention

This eliminates the need to acid-wash the filters in your lab

Glass Microfiber Filter Paper - 1310-0250 - Grade 131, 2.50cm 15cm zirconium and aluminum hydroxidesAhlstrom Munksj 131 1. 0 m, Medium Speed This standard grade found in many environmental applications offers slightly more retention than Grade 111 with slightly lower filtration speed and loading capacity. Grade 131 is recommended for the collection of suspended solids in potable water and in industrial wastes. In biochemical tests, Grade 131 is suited for cell harvesting, liquid scintillation counting and the analysis of carbohydrates.
