Stopping The Centrifuge Run; Short-Term Centrifugation; Removing The Rotor - Thermo Scientific 75007202 Instruction Manual

Chapter 4 | Short-term Centrifugation

Stopping the Centrifuge Run

With Pre-Set Running Time
If the run time is preset, the centrifuge will run at the selected speed until the desired run time is reached. It will then
automatically decelerate and stop. Once stopped "RUN COMPLETED" will be displayed and if selected the display will flash.
Access to the chamber and rotor can be gained by pressing the OPEN key. If selected the door will open automatically.
You can also stop the centrifuging program manually at any time by pressing the STOP key.
Continuous Operation
If you selected continuous operation
on the control panel. The centrifuge will be decelerated at the set rate. The message "RUN COMPLETED" will be displayed.
After pressing the OPEN key, the centrifuge door will open and you can remove the centrifuged samples.

Short-term Centrifugation

For quick centrifugation, the Thermo Scientific Sorvall ST 8 / 8R has a PULSE-function.
By holding down the PULSE key, spinning will start at maximum acceleration rate, continue at maximum rotor speed until
the key is released. The rotor then decelerates at maximum rate. Preset values for acceleration, deceleration and speed
or RCF are disregarded for the PULSE function.
The centrifuge accelerates and brakes at maximum power. Any rpm or RCF entered beforehand is overridden.
NO T I CE
The centrifuge accelerates to maximum speed according to the rotor used.
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
door is opened.

Removing the Rotor

To remove the rotor, proceed as follows:
1. Open the centrifuge door.
2. Grab the rotor handle and fully depress the Auto-Lock button. At the same time, pull the rotor vertically upwards and
remove it from the centrifuge spindle. Make sure not to tilt the rotor while doing this.
