Program 9 and 10 slow pressure – 250
This program is intended for materials that require a slow pressure exhaust
and other goods, which its manufacturer declares their compliance to be
sterilized in the following conditions:
♦
Sterilization temperature 250ºF
♦
Sterilization time: 15 min.
♦
Slow discharge of the pressure.
Performance description:
Residual air
is displaced due to 3 vacuum pulses (down to 25 kPa) and 2
steam pulses up to 160 kPa. The 3rd vacuum pulse is followed with
introducing saturated (controlled) steam into the chamber to the required
sterilization temperature.
Sterilization period is controlled in such 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 the fluctuation of pressure does not allow a drop below
1kPa, neither an increase of 3 kPa above the high limit of the Ste.
Temperature.
Slow exhaust stage is performed by discharging the pressure very slowly
from the chamber. When the pressure reaches a level of 115 kPa the ejector
is activated till 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 temperature of the chamber must be below 203ºF and the pressure must
be below 115 kPa to enable the door to be opened.
