Descriptions cycles
The autoclave has three series of cycles:
A - operation cycles
B - night cycles
C - test cycles
9.2
Operation cycles
All operation cycles have a system of fractioned vacuum, which therefore permits
sterilization of materials that are hollow, porous, solid, both free and packaged.
Temperatures can be selected from 121°C – 134°C.
Normally the cycles of 121°C are used for thermoplastics or sensitive materials, while the
134°C cycles are used for all other materials.
In all cases always follow the indications given by the manufacturer of the instruments or
devices to be sterilized.
There are also two special cycles:
- Prion cycle, studied for the Crutzfeldt-Jacobs disease (mad cow disease)
- Flash cycle created for rapid sterilization of unpackaged instruments and devices.
9.3
Night cycles
The autoclave is provided with a special economizer device.
This device allows the execution of sterilization cycles without the presence of an operator.
At cycle end, if the door is not opened, the autoclave stabilizes and then shuts off
automatically. Only the general switch remains on (PICT.2 pos. 17.).
Upon the operator's arrival it is sufficient to press any button to re-start the autoclave and
read the cycle result on the display.
Besides that the printer will have regularly prepared the written report relative to the same
cycle.

Warmig up time and vacuum fractionation can vary, because of autoclave's conditions,
between 25 and 30 minutes. You have to an this time to sterilization's times showed in
