Operation
Set Temperature
A refrigerated centrifuge allows for preselecting a temperature for the sample (GUI versions) or centrifugation
chamber temperature (LCD control panel) between -10 °C and +40 °C for the centrifugation run. This feature is
not available on ventilated models.
2. 8. 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.
2. 9. Centrifugation
WARNING Damage to health from centrifuging explosive or flammable materials
or substances.
Do not centrifuge explosive or flammable materials or
substances.
CAUTION Due to air friction the temperature of the rotor may rise significantly while
the centrifuge is spinning. Displayed and set temperature can deviate
from sample temperature. Sample temperature might exceed critical
temperature of your apllication.
Mind the safety zone of minimum 30 cm around the centrifuge. Refer to “Safety Zone” on page 1-2. Persons
and hazardous substances must be kept out of this safety zone while centrifuging.
Once the main switch has been turned on, the rotor has been properly installed, the setpoints have been set as
explained in the previous section, and the centrifuge lid has been closed, you are ready to start.
You have various options to start a centrifugation run with a GUI:
ƒ
Continuous Mode: This is a fully manual mode. If you have chosen Continuous Mode instead of a preset
runtime (see
“Set Run Time” on page 3-8 ), use the Start button and Stop button to start and stop
centrifugation manually, as explained in the section “Run in Continuous or Timed Mode” on page 3-12
further below.
ƒ
Timed Mode: This is a semi-automatic mode that relies on a timer. If you have preset a runtime (see “Set
Run Time” on page 3-8 ), tap the Start button , then and wait for the timer to expire and the centrifuge
to stop automatically, as explained in the section “Run in Continuous or Timed Mode” on page 3-12 .
ƒ
Pulse Mode: This is a short-run centrifugation mode with selectable behaviors. You choose a behavior,
then tap the Pulse button and wait for the centrifuge to run and stop automatically, as explained in the
section
“Run in Pulse Mode” on page 3-13.
ƒ Program Mode: This is a fully automatic mode. You prepare and save an automated program, then run it
from the touchscreen, as explained in the section
“Automate Processes Using Programs” on page 3-20 .
