After the sterilization process, allow the pressure to naturally release before opening the cooker.
This can take an additional 20 to 30 minutes.
Handling the substrate before it has completely cooled can be a contamination risk, so patience is crucial.
Keep in mind that these are general guidelines.
Refer to specific instructions relevant to the substrate being sterilized, as some variations might apply due to density or composition.
Always exercise caution when using a pressure cooker for sterilization to ensure safety and effectiveness.
