Internal pressure of sealed containers during autoclaving.
The use of steam as a sterilizing media for rigid, fixed volume containers is routine. When applied to less rigorous packages this process can cause package failure and product contamination or loss. A study has been carried out verifying the validity of a previously developed equation by measuring the actual pressures generated during sterilization in a small container system.

Computer interface for vial sealing force measurements.
The force applied to the closure of a parenteral container is a critical parameter in assuring the integrity of a seal. Measurement of the force can be accomplished either off line, through residual force measurements, or on line, through instrumentation of the sealing station. The instrumentation of the sealing station provides a dynamic profile of the sealing event for development of the optimal sealing parameters. A computer interface for this application has been developed using a standard IBM-AT and commercially available data acquisition hardware and software. The resultant data can be set up in Lotus 1-2-3, or any other analysis package capable of importing ASCII files, for graphic display, and/or additional analysis. The system thus provides a means to acquire quantitative data on the sealing event for development of optimal sealing parameters.
