Does anyone know someone/somewhere that can help me with the hydrothermal aging of biomedical zirconia in an autoclave at 134 C, 0.2 MPa for 5 hours?

I am planning to do the aging process according to the ISO 13356/2015 in an autoclave for 5 hours.

Does it have to be autoclaved for 5 hours at once (in only one long cycle) or can it be made on many cycles?

I don't know if there is someone or somewhere which has an autoclave that can run at these specs for 5 consecutive hours!

Do you know someone or somewhere that can help me with that?
