MICROWAVE HEATING OF MEDIA
Oxoid do not recommend the use of microwave ovens for sterilisation or re-melting of media. The reasons for this are:
1. Heating may be uneven.
2. Hot spots can occur in the column of medium leading to superheating and explosion of the containers.
3. Microwave sterilisation is effective only where there is moisture. The inside tops of the containers, if not previously sterilised, may constitute a source of later contamination.
