Read the Operating Instructions carefully, before beginning any
operation on the autoclave!
1.1 Introduction
Model 2840 ELCPVG is a laboratory sterilizer designed especially for
the sterilization of instruments, liquids, and other materials in hospital
laboratories, medical laboratories, research institutes, food laboratories
and pharmaceutical facilities.
A computerized control unit ensuring a fully automatic sterilization cycle
controls the autoclave.
The PV (pre-vacuum) models are equipped with a vacuum pump.
The advantages of the pre-vacuum sterilizer in comparison to the
regular gravity displacement steam sterilizer are as follows:
 Removal of air pockets from packs and porous loads and most kinds of
tubes (rubber, plastic etc.) by vacuum at the first stage of the cycle.
 Better steam penetration into the load; resulting in effective
sterilization.
 Better temperature uniformity.

Better drying of materials with closed doors due to the vacuum
achieved in the chamber at the end of the sterilization cycle.
In BH (bio-hazard) models, a bio-hazard filter installed in the chamber
enables sterilizing bio-hazard load without contaminating the
surrounding.
There is a configuration equipped with fan that allows shortening the
cooling operation.
The temperature and pressure are controlled through sensors placed
inside and outside the media container or bottles.
The autoclave is equipped with A 9Kw generator that produces the
steam required for the sterilization.
A special feature of the autoclave is the fast cooling stage for liquids. In
this stage pressure in the chamber is increased by means of
compressed air to compensate the fast decreasing of pressure due to
the fast cooling. The fast cooling shortens the time required for safe
handling of bottles.
