Type of the feed water supply

The steam sterilizer works with a one-way
or distilled water) for every sterilization procedure. The quality of the feed water is subject to permanent monitoring via
integrated conductivity measurement. If combined with careful preparation of the instruments, this serves largely to pre-

(such as temperature, time and pressure) during a program run. It monitors the parameters in terms of their threshold
values during control and regulation and guarantees safe and successful sterilization. A monitoring system checks the
device components of the steam sterilizer for their functionality and their plausible interaction. If one or more parameters
exceeds pre-determined threshold values, the steam sterilizer issues warnings or malfunction messages and if neces-
sary, aborts the program. In the case of a program abort, follow the instructions on the display.
The steam sterilizer uses an electronic parameter control. This enables the steam sterilizer to optimise the total operating
time of a program in dependence on the load.
Internal logic monitoring
The electronics of the steam sterilizer monitor the successful program run by means of two separate test processes.
When a program has been successfully completed, it is shown on the display as a successful program. In addition, the
status LED below the display illuminates green.
Door mechanism
The steam sterilizer constantly checks pressure and temperature in the sterilization chamber and prevents the door from
being opened when over-pressure has built up.
Automatic monitoring of the feed water

Description
Pressure release
The sterilization phase is followed by pressure release from the sterilization
chamber.
Drying
The sterile material is dried using a vacuum (vacuum drying).
Ventilation
Upon program end, the sterilization chamber is filled with sterile air via the sterile
filter and adjusted to the ambient pressure.
Description
The sterilization chamber is evacuated until the pressure for the vacuum test has
been reached.
An equilibration time of five minutes will follow.
The measurement time amounts to ten minutes. The pressure increase within the
sterilization chamber is measured during the measurement time. The evacuation
pressure and the equilibration time or measurement time are shown on the display.
The chamber is ventilated after the end of the measuring time.
The display shows the test result, the batch number, the total number of batches
and the leakage rate.
