The centrifugation data are temporarily stored at program location
can be retrieved after each start of a centrifugation run.
No programs can be stored in program location
■
Rotor detection is performed after starting a centrifugation run.
■
If the rotor has been changed, the centrifugation run is cancelled after
rotor detection. The rotor code (Rotor), the maximum rotor speed
(Nmax) and the centrifuging radius (R) of the newly detected rotor are
displayed.
■
If the maximum speed of the rotor used is less than the set speed, the
speed is limited to the maximum rotor speed.
In this case, the program location number is displayed in brackets
■
If the cycle counter is enabled, the number of completed run cycles
(centrifugation runs) of the rotor code used is displayed briefly after
opening the lid.
To achieve an exact temperature, a pre-tempering run of up
to 60 minutes must be carried out before each centrifuga-
tion run.
The temperature setpoint can be adjusted from -20 °C to +40 °C or from
-4 °F to +104 °F.
For centrifuges with the heating/cooling option, the temperature setpoint
can be adjusted from -20 °C to +90 °C or from -4 °F to +194 °F .
The lowest achievable temperature is rotor dependent.
When the rotor is at a standstill and the lid is closed, the centrifuging
chamber is cooled to the preselected temperature if this is less than 20 °C
or 68 °F.
The preselected temperature is displayed during standby cooling.
For rapid pre-cooling of the unloaded rotor and accessories, we recom-
mend a centrifugation run with the continuous run settings and a speed of
■
Swing-out rotor: approx. 20% of the maximum rotor speed used.
■
Angle rotor: approx. 40% of the maximum rotor speed used.
The centrifugation run, for precooling of the rotor, takes place automatically
with the PREC program (PRECOOLING).
A centrifugation run, for precooling the rotor, cannot be executed when
working with program links.
The rotor is stationary.
