Density
This setting is useful for glass vessels. If the density of the liquid to be
centrifuged is higher than 1.2 g/cm
3
, the value must be adapted manually in
order to prevent the glass vessel from breaking. This will reduce the
maximum possible final speed (see chapter 2.2.2.2 - "Density"). The
reduction will be represented by a downward facing arrow "
↓
" in the speed
field. Values between 1.2 and 10.0 g/cm
3
are possible.
Centrifugation monitoring
The centrifugation monitoring function enables the continuous monitoring of
the speed and runtime parameters during the centrifugation.
• Activate the centrifugation monitoring function by clicking.
NOTE
If the function is activated during a centrifugation run, the monitoring
process will not be started until the start of the next centrifugation run.
The centrifugation monitoring function compares the speed values of the
current run with the reference values that are stored in the control unit.
After every run, it issues a corresponding message.
The runtime is considered faulty if the centrifugation run had to be stopped
prematurely.

NOTE
If the centrifugation monitoring system is used in combination with free
acceleration or deceleration curves, unjustified error messages may result
in certain cases.
