Be very careful if you sterilise fluid in sealed glass containers. 

Proper autoclaves for processing this type of load have built in safety 
controls that stop the doors being opened until the load is below 80°C, 
you don't have this with a pressure cooker.

The risk of the glass containers bursting when exposed to cold air is 
very real if the contents are above 80°C.
