PYREX® 3L Buchner Funnels with 152 mm Diameter Medium Porosity Fritted Disc

Description

These 3L PYREX® Buchner funnels have a 152mm 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.î The disc should not be subjected to pressure differential in excess of 1 atmosphere. The top edge is beaded.

These funnels are especially useful where filter paper would be attacked by the material being filtered. The disc should not be subjected to pressure differential in excess of 1 atmosphere. The top edge is beaded.
