Program 3 & 4 - for Unwrapped goods (Fast 270/274)
This program is intended for unwrapped rigids (like instruments) and other
goods, which its manufacturer declares their compliance to be sterilized in the
following conditions:
♦
Sterilization temperature 270ºF (for program 3) and 274ºF (for program 4)
♦
Sterilization time: 5 mins.
♦
Dry time: 15 mins.
Performance description:
Residual air
is displaced due to 3 vacuum pulses (down to 25 kPa) and 2
steam pulses up to 199 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 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.
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.
