Corning These 150mL PYREX® Buchner funnels have a 60mm diameter fine porosity fritted disc with a porosity range of 4 to 5.50µm 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. Please check our Technical Information Listing on fritted ware, see Guide to Selecting and Using Fritted Glassware.'Borosilicate Glass Code 7740 - COG
