Buchner Funnel, 30 ml, 139 mm H, Borosilicate Glass, 47 mm Height Above Disc, 30 mm Disk OD, 8 mm Stem OD, Fine Porosity Fritted Disc, 4 to 5.5 µm Disc Porosity Size, 75 mm Stem Length
These 30 ml Pyrex® buchner funnels have a 30 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.
