Changing program links


Call up the desired program (see Chapter "Calling up programs"), change the desired parameters (see Chapter
"Entering centrifugation parameters"), and save the modified centrifugation data to the same program location
(see Chapter "Entering / modifying programs"). As a result of saving, the program linking will be removed.

Re-link the programs (see Chapter "Linking programs").

Cooling (only in centrifuges with cooling)

The temperature set-point can be adjusted from -20°C to +40°C. On centrifuges with a heating/cooling option, the
temperature set-point is settable from -20°C to +90°C. The lowest obtainable temperature is dependent on the rotor
(see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories"). If the actual temperature and the
set temperature deviate more than 5 °C, the temperature value in the display will start to flash on and off.
29.1

Standby-cooling

With rotor standstill and closed lid the centrifugal chamber is cooled to the pre-selected temperature. The
temperature set-point is shown in the display.
29.2

Pre-cooling the rotor

For rapid pre-cooling of the unloaded rotor and the accessories, it is recommended that the centrifuge is run with the
continuous running settings and a speed of ca. 20% of the maximum rotor speed.
30

Heating (only on centrifuges with heating/cooling option)

During operation of the centrifuge the centrifuge chamber can be heated as required to the preselected temperature.
The heating is switched off when the rotor is stationary.
Risk of burning! The surface temperature of the heating element in the centrifugal chamber of the centrifuge
can reach 500°C / 932°F. Do not touch the heating element.
During a centrifugation run at very high temperature (e.g. +90°C), the inside of the device lid heats up. In
this case, do not touch the inside of the lid.
