Buchner Funnel, 350 ml, 180 mm H, Borosilicate Glass, 75 mm Height Above Disc, 80 mm Disk OD, 20 mm Stem OD, Coarse Porosity Fritted Disc, 40 to 60 µm Disc Porosity Size, 75 mm Stem Length
These 350 ml Pyrex® buchner funnels have a 80 mm dia 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 of 1 atmosphere. The top edge is beaded.
