PYREX® 3L Buchner Funnels with 152 mm Diameter Fine Porosity Fritted Disc
Corning Life SciencesThese 3L PYREX® Buchner funnels have a 152mm 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 of…
