Explore MoreGlass Buchner funnels containing fritted discs are especially useful where filter paper would be attacked by the material being filtered. Porosity is given by the range specified below with pore size held toward the minimum pore diameter. Complies with ASTM E-128 as described in Maximum Pore Diameter and Permeability of Rigid Porous Filters for Laboratory Use. Customized by our glassblower to have a standard taper female 10/30 ground glass joint at the top, so it can be connected to other glassware if needed. The original funnel appears to have been catalogue number 7186-04 and its original outer diameter was slightly smaller than that of the 10/30 joint stem. The spacing between the fritted disc and the bottom of the ground glass taper is about 5 cm, so we estimate a capacity of 4 mL. Specs (approximate): capacity, ~4 mL; disc diameter, 10 mm; joint height above disc, 50 mm (original 30 mm); stem outer diameter, 6 mm; maximum pore diameter range, 70 to 100 µm (porosity B, intermediate between Corning C and EC) Ships on the next business day by USPS (USA only).

Note: Due to recent price increases from all carriers, listings with “Free Shipping” will now have a small shipping fee added for West Coast destinations. Sorry, but the alternative would be to raise purchase price for everyone. All items ship from Gainesville, FL. These 600mL PYREX® Buchner funnels have a 90mm diameter coarse porosity fritted disc with a porosity range of 40 to 60µm 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. Useful where filter paper would be attacked by material being filtered 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.
