ABSTRACT:
A cassette containing a group of sealed cells is used as a means for delivering doses of fluid to be injected into a sterilizing chamber. After the cassette is automatically positioned over a piercing mechanism, the cassette is moved downwardly so that a cell is pierced. Fluid is then forced out of the cell by pneumatic pressure into an injector valve, which opens in a manner which does not adversely affect a vacuum within the chamber.
