Program 6 for Wrapped goods 121ºC (Process Sample)
This program is intended for wrapped goods, for example instruments and other goods,
which their manufacturer declares their compliance to be sterilized in the following
conditions:
Sterilization temperature 121ºC
Sterilization time 15 minutes
Drying time 15 minutes
Performance Description:
Residual air is displaced by 4 vacuum pulses (down to 25 kPa) and 3 steam pulses up
to 160 kPa. The 4
th
vacuum pulse is followed by the introduction of saturated (controlled)
steam into the chamber to the required sterilization temperature.
Sterilization is controlled in a way that the sterilization temperature will not drop below
the required temperature nor increase by more than 3ºC. The steam conditions are
controlled in such a way that the fluctuation of pressure does not allow a drop below 1
kPa, nor an increase over 3 kPa, above the high limit of the Ste. Temperature.
Fast exhaust is performed by rapidly discharging the pressure from the chamber. The
vacuum pump is activated to create a vacuum in the chamber for drying.
Drying is achieved by evacuating the vapors from the chamber in an "under pressure"
phase for a period of 15 minutes.
Pressure equilibrium enables the opening of the door. Air is introduced into the
chamber through a microbiological filter until equilibrium is reached with atmospheric
pressure.
Important:
In order to obtain good sterilization results, dry time is essential.
Note:
The pressure must be below 115 kPa to enable the door to be opened.
