Eppendorf 5702 RH Centrifuge - Manual (Page 12)

The inner part of the aerosol-tight cap is also equipped with a silicone sealing ring. Never remove this sealing ring from
the cap. Whenever using the cap, make sure that the sealing ring is undamaged and sits uniformly in the groove.
The round bucket and the aerosol-tight cap are autoclavable (121 °C, 20 minutes). The aerosol-tight cap, including the
silicone sealing ring, is subject to natural wear and must be replaced when visual inspection reveals wear.
When handling the aerosol-tight cap, remember that polycarbonate has limited chemical resistance to phenol.
Switch on the centrifuge, with the mains power switch if necessary, and then with the switch. The nominal values of
the last run are displayed. Load the rotor symmetrically and close down the centrifuge lid.
While the centrifuge is running the remaining time is displayed. The last minute is counted down in seconds. When the
preset time elapses the centrifuge stops automatically and emits a signal tone to indicate the centrifugation is finished.
The lid of the non-refrigerated Centrifuge 5702 opens automatically following centrifugation. The lid of the refrigerated
Centrifuge 5702 R / 5702 RH remains closed to maintain the sample temperature and can be opened with the OPEN
button.
When you switch off the centrifuge 5702 / 5702 R / 5702 RH at the main power switch the display goes blank after a few
seconds' delay.
The timer setting, the rotation speed and the temperature (only 5702 R / 5702 RH) can be changed during the run by
briefly pressing the SHORT button. The display begins flashing. You can then set the new centrifugation parameters with
the TIME and SPEED and the TEMP dial adjustors. The new centrifugation parameters are programmed after 5 seconds.
time – Alters the running time.
speed – Alters the speed in increments of 100 1/min or rcf.
start – Starts the run. The symbol flashes while the rotor is running .
stop – Stops the centrifuge. The symbol appears briefly as soon as the rotor comes to a
standstill.
stand-by – Centrifuge switched to stand-by mode.
open – Releases the lid latch.
temp – Changes the nominal temperature value (for 5702 R / 5702 RH only)
short – Press this button with the lid closed to start a short run at maximum speed.
The centrifuge stops when you release the SHORT button again.
