Hot surfaces

The screen of the glass door, the interior panel of the outer door, the
Peltier system at the rear side, as well as the surfaces of the shelving
and the work space become hot while the low temperature incubator is
running through its heating cycles and need some time to cool down.
When removing samples from a running or recently completed heating
cycle, always wear safety gloves and other appropriate personal
protection equipment to avoid burns on hot surfaces!

Risk of overloading

Overloading may damage the shelves or cause the shelves
and/or the low temperature incubator to tilt when the shelves are
being drawn out, ultimately destroying the samples. To avoid
overloading the low temperature incubator or its shelving be sure
to observe the sample weight limits specified in
chapter 13,
“Technical Data.”

Proper loading

To ensure sufficient air circulation and uniform heating of the samples,
do not use more than 70% of the maximum surface area of the work
space. Bulky objects in the work space that dissipate heat may impair
heat distribution.
During tempering of defined substances or materials with higher
moisture content, the access port is to be opened in order to reduce a
possible condensation in the chamber. If necessary a modified door
seal is available as an accessory.
