3. 3. Pre-Temper the Centrifugation Chamber
Refrigerated centrifuges allow for pre-tempering, that is pre-warming or pre-cooling, the centrifugation chamber
and the empty rotor before the centrifugation run starts. If necessary pre-temper your samples using proper
equipment. The centrifuge is not intended to be used to pre-temper your samples.
NOTICE Ventilated models cannot pre-temper the centrifugation chamber.
Proceed as follows to set the pre-tempering target temperature for the centrifuge:
1. Tap the temperature box on the “Home” screen, shown in Figure 3–22 below.
Figure 3–22: Temperature Box on Home Screen
The “Setpoints: Standard” screen shown in Figure 3–13 or “Setpoints: Advanced” screen shown in Figure
3–14 appears.
2. Tap in the
Temp
entry field, then use the keypad on the right to enter the desired target temperature.
The admissible temperature range for the unit appears just below the “Temp” label to assist you in setting
target temperature correctly.
When you tap the
Temp entry field, the previous setting will be replaced immediately as you start entering
digits on the keypad.
3. Tap the Save button to save the temperature setting for the pre-tempering run.
You will be returned to the “Home” screen. The new target temperature appears as the setpoint below the
current temperature.
4. Tap the Pre-Temp button on the “Home” screen and then the Start button to start pre-tempering.
The centrifuge starts heating or cooling the centrifugation chamber to the setpoint temperature.
The current centrifugation chamber temperature displayed on top of the setpoint temperature starts to
change towards the setpoint.
5. When the centrifugation chamber temperature reaches the pre-tempering setpoint, the “Pre-Temp Complete”
pop-up window shown in Figure 3–23 appears, announcing that the centrifuge is correctly pre-tempered
and ready.
