3. TECHNICAL DATA
3.1 Introduction
Models 3840, 3850, and 3870 EL-D and ELPV are table-top sterilizers
designed especially for sterilization of instruments, liquids medical waste,
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 temperature and pressure are controlled through sensors placed inside
and outside the media container or bottles.
Special feature of ELCPV-D model is the vacuum pump that enables air
removal prior to sterilization and during the drying stage.
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.
The sterilizer is equipped with a fan on the door to shorten the cooling
operation.
There is a configuration equipped with fan that allows to shorten the
cooling operation.
The sterilizer is fully automatic with a choice of seven programs
(including vacuum test program), eliminating any need for operator
intervention during a cycle. The custom programs are programs that may
be changed by an authorized person. A computerized control unit enables
precise control and monitoring of physical parameters and clear
documentation of the sterilization cycles.
The autoclave is equipped with a safety valve, which blows off at 280 kPa
(40 psi) (max. working pressure). The safety valve is located in the mineral
free water reservoir. The control system provides adequate protection, to
ensure the safety of personnel and reliable operation with a minimum of
down time.
On all models, a printer is an optional addition to the autoclave. The
printer prints the preset and actual parameters of the cycle (temperature,
time and pressure/vacuum).
The autoclave is provided with a pressure gauge that is used as guide only.
Should there be a power failure during the operation of the autoclave, the
pressure gauge indicates to the operator that there is pressure in the
chamber.
A deviation of +1.6% is accepted.
