Sterilisation in Autoclave: Recommended Procedure

During autoclave sterilisation, it is essential that screw caps are not placed on the bottles. This applies to all types of threaded closures, as the pressure and temperature involved in the cycle may cause deformation of both the container and the cap, compromising their structural integrity and sealing capability.

It is recommended to sterilise components separately: caps should be placed in autoclave-safe bags, and bottles sterilised independently.

The assembly should only be carried out once both elements — the bottle and the cap — have cooled down completely and are in a sterile condition.
