These 350 mL PYREX® Buchner funnels have a 80mm diameter fine porosity fritted disc with a porosity range of 4 to 5.5 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…

These 350 mL PYREX® Buchner funnels have a 80mm 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 exce…

These 3L PYREX® Buchner funnels have a 152mm diameter coarse porosity fritted disc with a porosity range of 40 to 60 µm which is held toward the maximum 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…
