ABSTRACT:
Apparatus for dispensing metered amounts of mercury and silver alloy, for the production of dental amalgam, is disclosed. The apparatus can dispense the silver alloy in either tablet or powder form and is provided with a stirring member in the silver alloy powder supply container to agitate the powder during the metering and dispensing thereof so as to alleviate the problem of clumping. The apparatus also has a member to adjust the amount of mercury being dispensed and an element for locking the adjusting member securely against accidental shifting out of position.
