Program 7- for Wrapped materials (with Dry 274)
This program is intended for wrapped materials (like instruments), porous load
and other goods, which its manufacturer declares their compliance to be
sterilized in the following conditions:
♦
Sterilization temperature 274ºF
♦
Sterilization time: 7 mins.
♦
Drying period of 15 mins.
Performance description:
Residual air
is displaced due to 4 vacuum pulses (down to 25 kPa) and 3
steam pulses up to 199 kPa. The 4th 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.
Fast exhaust stage is performed by discharging rapidly the pressure from the
chamber. When the pressure reaches a level of 115 kPa the ejector is
activated till a pressure drop to 25 kPa .
Drying is achieved by evacuating the vapor from the chamber in
"under-pressure” phase along a period of 15 minutes.
Pressure equilibration . To enable the door to be opened, air is introduced to
the chamber through a microbiological filter till the equilibration with
atmospheric pressure.
Note:
The temperature of the chamber must be below 230ºF and the pressure must
be below 115 kPa to enable the door to be opened.
