Due to air friction sample integrity may be affected.
The temperature of the rotor may rise significantly while the centrifuge is
spinning. Ventilated units lead to a heat up of the rotor above the ambient
temperature. Refrigerated units can have a deviation from displayed and
set temperature to the sample temperature.
