Operation
Temperature Adaptation during Standstill
Thermo Scientific
Multifuge X1 / X1R
4-11
If you selected continuous operation (see “Continuous operation” on page 4-6), you will have to stop
the centrifuge manually. Press the STOP key
on the control panel. The centrifuge will be
decelerated at the designated rate. The message "END" will illuminate, and after pressing the key
OPEN
, the lid will open and you can remove the centrifuged material.
Temperature Adaptation during Standstill
The temperature cannot be adapted until the rotor has been positively identified. For this, the
centrifuge must have accelerated to over 500 rpm. The speed display will then show END.
When the rotor is not recognized (lid closed and START key
not yet pressed, speed display "0"),
the centrifuge responds by ensuring that the sample cannot freeze regardless of the rotor being used.
Short-term Centrifugation
For short-term centrifuging, the Heraeus Multifuge X1 / X1R has a PULSE- function.
By holding down the PULSE key
, spinning will start and continue until the key is let go.
The centrifuge accelerates and brakes at maximum power. Any rpm or RCF entered beforehand is
overridden.
Check carefully whether you have to maintain a certain speed for your application.
During the acceleration process, time is counted forwards in seconds. The reading stays displayed until
the centrifuge lid is opened.
Removing the Rotor
To remove the rotor, proceed as follows:
1. Open the centrifuge lid.
2. Grab the rotor handle with both hands and press against the green AutoLock
TM
key. At the same
time, pull the rotor directly upwards with both hands and remove it from the centrifuge spindle.
Make sure not to tilt the rotor while doing this.
Note
The centrifuge accelerates to maximum speed, regardless of which rotor was installed.
