36060-3LM PYREX 3L Buchner Funnels with 152mm Diameter Mediu

Corning These 3L PYREX® Buchner funnels have a 152mm diameter medium porosity fritted disc with a porosity range of 10 to 15µm 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. - COG
