Glass Microfiber Filter Paper - 1210-1100 - Grade 121, 11cm 151 83 mm - 220 mm

83 mm - 220 mm / 30 min

This is a fast filtering grade for gravimetric analysis of coarse particles and gelatinous precipitates (i

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

This grade has similar performance properties to Grade 151 and is made with acid-treated borosilicate glass microfibers with inherently low levels of barium and zinc

Glass Microfiber Filter Paper - 1210-1100 - Grade 121, 11cm 151 83 mm - 220 mmAhlstrom Munksj 121 1. 0 m, Medium Speed This very thick grade offers finer particle than Grade 111 with high wet strength and loading capacity. Grade 121 is recommended for the clarification of liquid suspensions loaded with fine particulates. Grade 121 is also used in membrane pre filtration and is also found in quantification of solids, and LSC (Liquid Scintillation Counting) techniques that require high loading capacity.
