3.1 Programs description
If vacuum pulse is determined '= 0' in any program by the operator, the program
can be used as a 'Gravity' program. A message 'Gravity' is displayed on the right
side of the screen.
Program 1 and 2- for Unwrapped (Fast 250)
This program is intended for unwrapped rigid parts (i.e. instruments) and other
goods, which its manufacturer declares their compliance to be sterilized in the
following conditions:
♦
Sterilization temperature 250ºF
♦
Sterilization time: 15 min.
♦
Dry time: 10 min.
Performance description:
Residual air is displaced due to 3 vacuum pulses (down to 25 kPa) and 2 steam
pulses up to 160 kPa. The third vacuum pulse is followed with introducing
saturated (controlled) steam into the chamber to the required sterilization
temperature.
Sterilization period is controlled in a way that the sterilization temperature will not
drop below the required temperature; neither will increase by more than 37.4ºF.
The saturated steam conditions are controlled in such a way that fluctuation of
pressure does not allow a drop below 1kPa, neither an increase of 3 kPa above
the high limit of the Ste. Temperature.
Fast exhaust stage is performed by discharging rapidly the pressure from the
chamber. When the pressure reaches a level of 115 kPa the vacuum pump is
activated until a pressure drop to 25 kPa.
Pressure equilibration . To enable the door to be opened, air is introduced to the
chamber through a microbiological filter till equilibrium with atmospheric pressure.
Note:
The pressure of the chamber must be below 115 kPa to enable the door to be
opened.
