Abb. 6.29: Standard Menu
This menu is displayed a few seconds after the centrifuge has been
switched on.
The following parameters can be displayed and modified:
Speed
In the upper section of the field, the set speed of the centrifuge is
displayed. The actual speed is displayed below this value. The values
are stated in revolutions per minute (rpm) and depend on the RCF
values (see 11.4 "Formulae – Mathematical Relations "). The
maximum speed values depend on the rotor that is used.
Relative Centrifugal Force (RCF)
The relative centrifugal force is the acceleration that the sample is
subjected to. The set value of this parameter is displayed in the upper
section of this field, with the actual value shown below. The values
are stated in g (gravitational acceleration) and depend on the speed
value (see11.4 "Formulae – mathematical relation"). The maximum
RCF values depend on the rotor that is used.
Temperature
The set temperature is displayed in the upper section of the area, with
the current rotor chamber temperature shown below. Temperatures
between -20 °C and +40 °C can be preselected.
In the centrifuges without an active heater, the temperatures above
room temperature depend on the air friction of the running motor.
The centrifuge 3-30KH with a heater enables the preselection of
temperatures up to +60°C. The maximum rotor temperature that can
actually be reached is 40-60°C, depending on the rotor and speed.
