Buchner Funnel, 15 ml, 136 mm H, Borosilicate Glass, 47 mm Height Above Disc, 20 mm Disk OD, 8 mm Stem OD, Medium Porosity Fritted Disc, 10 to 15 µm Disc Porosity Size, 75 mm Stem Length
These 15 ml Pyrex® buchner funnels have a 20 mm diameter medium porosity fritted disc with a porosity range of 10 to 15 µm which is held toward the minimum pore diameter . The porosity for the pore diameter of the filter is determined in the same manner as specified in ASTM E-128 "maximum pore diameter and permeability of rigid porous filters for laboratory use." The disc should not be subjected to pressure differential in excess of 1 atmosphere. The top edge is beaded.
