Zusammenfassung:	The present invention is directed to a method an apparatus for buffering an anesthetic solution prior to an injection. The inventive apparatus employs a modified carpule which hold two solutions in fluid isolation. The buffering solution is separated from the anesthetic solution within the same carpule by way of a fluid impervious thin film. The thin film has a weakened central area which can be easily pierced by a harpoon affixed to one side of a plunger. As the plunger is advanced forward, the harpoon breaks through the thin film and causes mixing of the two solutions.
