A Shorter Sterilising Cycle for Solutions Heated in an Autoclave

Abstract

The rapid cooling of bottles in an autoclave after steam sterilisation has been investigated. A coarse cold water spray caused breakage by thermal shock, whereas a fine spray prevented this. The time of cooling using this method has been compared with the usual cooling cycle and with that achieved when air was circulated in the chamber. Experimental data for a steriliser containing a charge of 200 × 1 litre bottles is given.
