Stainless steel material of AISI 316L durable grade has been used for constructing the Chamber. Fully jacketed chambers that range from 2000 to 8720 liters in volume have been used on the bulky models of the autoclave. Requirements that are end user specific can be easily achieved through chambers that are custom built. The interior wall surface of the chamber is finely polished to a shine and has a RaValue that is less than equal to 0, 8 micro m. Any amount of load that needs to be sterilized can be accommodated easily into each autoclave. Uniquely designed racks and trolleys are provided to place smaller items. Every autoclave model ships with a single or a double door configuration. Stainless steel of AISI 316L grade material has been used for the construction of doors with each of them being horizontally sliding and functioning through a mechanism of pneumatic nature. A high grade of silicon profile has been used to secure the closure of the doors, achieved through compressed air.
