There is a common missconception that if you keep pumping you can get harder and harder vacuums.
The pressure? In absolute terms ...zero!
In practical terms in free air on the Earths surface the pressure is 1 atmosphere acting to collapse your pressure vessel.
Any pump can only pull 1bar ... it may well be able to generate a positive pressure of several bar.
A vacuum is nothing at all...if you heat it up it's still nothing so it's conditions will not change.
