Intended use

The steam sterilizer is mainly intended for use in the medical field, e.g. in physician and dental practices. The steam ster-
ilizer is a small steam sterilizer according to
effective steam penetration of the load with saturated steam. It is suitable for reprocessing instruments and materials that
may come into contact with blood or body fluids during treatment. The steam sterilizer is not intended for use on patients
or in the patient's environment and is not intended for the sterilization of liquids.
WARNING
Any attempt to sterilize liquids can result in a
the device.
Never use this device to sterilize fluids. It is not licensed for the sterilization of fluids.

Sterilization procedure

The steam sterilizer sterilizes on the basis of the
fective wetting/penetration of the
The steam sterilizer uses the double jacket technology to generate the sterilization steam, i.e. the steam sterilizer is fitted
with a separate steam generator combined with a double-walled sterilization chamber. After heating, steam is held con-
stantly available in the double jacket. This gives the walls of the sterilization chamber a defined temperature and protects
the sterilization chamber from overheating. This especially effective procedure supports the quick
from the sterilization chamber, the sterilization packaging and instrument cavities. This permits the sterilization of large
quantities of instruments or textiles directly one after each other, thereby achieving excellent drying results.

Program runs

A reprocessing program runs in three main phases: the air removal and heating up phase, the sterilization phase and the
drying phase. After program start, you can follow the program run on the display. It shows the chamber temperature and
pressure as well as the time until the end of drying.

Description
Air removal
The air removal phase comprises the conditioning and the fractionating phase.
During conditioning, steam is repeatedly injected into and removed from
the sterilization chamber. This generates over-pressure and the residual air is

removed. Then, during fractionation, the mixture of air and steam is evacuated from
the sterilization chamber and steam is injected. This procedure is also called the
fractionated vacuum procedure.
Heating
The continued steam injection into the sterilization chamber leads to an increase in
pressure and temperature which continues until the program-specific sterilization
parameters have been reached.
Sterilizing
If the pressure and temperature correspond to the program-dependent nominal
values, the sterilization phase begins. The corresponding process parameters
(pressure and temperature) are held at sterilization level.
