3 General Information
3.1
Intended Use
This table-top autoclave is designed for sterilization of medical and surgical
goods such as unwrapped and wrapped, solid, hollow, porous products and
tubes in ophthalmic, dental and medical clinics, first aid rooms, small
laboratories etc.
3.2
Introduction
This autoclave model is an electrically heated sterilizer using steam as a
sterilizing agent.
The autoclave is designed as Type B in accordance with EN13060.
This model is a prevacuum sterilizer having the following features;

An air removal stage (prevacuum), before starting the sterilizing stage.

A post-sterilization drying phase, based on the combined operation of
heat and vacuum with air inlet pulses.
There are the following safety devices installed in the autoclave to optimize its
safe operation:

Two safety thermostats, to prevent over-heating of the steam generator
and the chamber.

Two safety pressure valves to prevent over pressurizing the steam
generator or the chamber.

A digital display is used for monitoring and control purposes. This device
displays the pressure in kPa, psia or psig, according to the operator’s
needs. The pressure is displayed for both the pressure in the chamber
and the pressure in the steam generator.

Temperature can be displayed in either °F or °C according to the
operator’s needs.
The advantages of the prevacuum sterilizer are as follows:

Removal of residual air from packs and porous load and most kinds of
tubes (rubber, plastic etc.) by vacuum at the first stage of the cycle.

More efficient steam penetration into the load; assuring effective
sterilization.

Improved temperature uniformity throughout the chamber.

Better drying of materials due to the vacuum achieved in the chamber
during the drying cycle.
The printer prints the preset and actual parameters of the cycle (temperature,
time and pressure/vacuum).
This Manual is intended for the user and gives the user a general
understanding of the instrument and the best ways to operate and take care of
it in order to obtain effective results.
