The temperature cannot be adapted until the rotor has been positively identified. For this, the
centrifuge must have accelerated to over 300 rpm. The speed display will then show End.

Short-term Centrifugation

For short-term centrifuging, the Sorvall RC-4 has a PULSE- function.

Note The centrifuge accelerates to maximum speed, regardless of which rotor was installed.
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
