Glazed porcelain Buchner funnel for fast filtration. For use with non-jointed filter flask and seal or gasket to secure air tight connection. Porcelain is widely used in the chemistry laboratory because it has excellent resistance to all reagents except hydrofluoric acid, and is highly resistant to thermal shock while having a very low coefficient of expansion.
Avoid contact of heated ware with a cold surface. Carefully inspect labware prior to each use and do not use any product that appears defective. To prevent thermal stress cracks on porcelain ware do not exceed a heating/cooling rate of 200°C per hour.
