title: Pressure changes in bottles during sterilization by autoclaving.
abstract: A method is described to measure changes in pressure inside a bottle during autoclaving without disturbing the integrity of the seal. Experiments showed that, in a perfectly sealed bottle, the pressure rose to a maximum of 58.2 psi absolute. If the rubber linear was unable to maintain the seal, air leaked slowly from the bottle both during the heating-up and the early sterilization period.
