Buchner Funnel, 350 ml, 180 mm H, Borosilicate Glass, 75 mm Height Above Disc, 80 mm Disk OD, 20 mm Stem OD, Fine Porosity Fritted Disc, 4 to 5.5 µm Disc Porosity Size, 75 mm Stem Length
These 350 ml Pyrex® buchner funnels have a 80 mm dia 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 1 atmosphere. The top edge is beaded.
