ABSTRACT:
A dual compartment mixing vial having a center seal isolating one compartment from the other is provided with a stopper at its open end which embodies a rod that is slidably positioned therethrough. The rod, upon being pushed downwardly, abuts the center seal of the vial and causes it to be displaced, thereby permitting the contents of the two compartments to intermix within the closed vial. An activating cap is provided for preventing accidental movement of the rod and to facilitate intentional movement of it.
