my guess would also be on it being alright, it wasn't much and it's going to be sterilized anyway

My understanding has always been that you need to vent your pc to get all the air out. If you have a combinatiin of air and steam, it may warp your PC or create pockets that dont get sterilized



This is incorrect.  The purpose of the "vent" is to ensure all the substrate materials being sterilized reach boiling point at their internal core before wanting to begin to build pressure to 15 psi, or beyond. 

That makes sure everything in the PC is the exact same temperature, and that everything in the PC increases in temperature at the exact same rate, thus ensuring even sterilization.

The larger the substrate materials being sterilized,  the longer you are going to want to vent your PC for.  The pressure cooker won't warp either.



Actually ham it was correct
Just not the damage and warp part.

You vent to remove air.

Things will be different temperatures that's why autoclaves have load probes.
If air is present the temperature will not match the pressure on the saturated steam table

Check out my pressure cooker tek for some facts
