ABSTRACT:
The invention is a disposable syringe comprising a dispensing plunger, a mulling plunger, a mercury storage chamber, an alloy storage chamber, and a passage means between the chambers. Mercury and alloy are prepackaged in their respective chambers during manufacture. Use of the apparatus involves unblocking passage means thus allowing mercury and alloy to combine in a chamber. Mercury and alloy can then be mixed into amalgam by vibrating entire syringe. Mulling plunger compresses amalgam within chamber in which amalgam was mixed. Dispensing plunger then dispenses a portion of mulled amalgam through syringe and out its tip. Amalgam remaining in syringe can then be further mulled by additional compression with mulling plunger.
