4.10 Work space components
The work space of the incubator has only a minimum
of surface, thereby supporting both the prevention of
contamination and easy, effective decontamination.
4.10.1 Interior container
All components of the work space are made of
stainless steel and have a high-gloss polished,
absolutely smooth and easy-to-clean surface. Any
embossings have a large radius.
As an option, the interior container, the shelf system,
and the blower wheel with its cover can be made of
copper material.
Oxidation of copper components:
When exposed to heat and humid air, the
copper material of the interior container
will oxidize. This results in a discoloration
of the copper components during the test
run for checking the device functions.
Do not remove the oxide layer during
routine cleaning as the antimicrobial effect
of the copper material is based on it.
The components of the shelf system can be removed
easily so that only the easily treatable, surface-
reduced interior container [1] remains in the work
space for cleaning and manual disinfection works.
4.10.2 Optional split gas-tight screens
Equipment versions:
• HERAcell
®
150i with 3-segment gas-tight screen
[2],
• HERAcell
®
240i with 6-segment gas-tight screen
[3].
For devices that are equipped with the optional gas-
tight
screen, the contamination hazard is considerably
lower and the recovery times of the incubation
parameters are shorter for:
• work space temperature,
• CO

concentration,
• O
