Pre-Selecting Temperature; Pre-Selecting Speed/Rcf - VWR Micro Star 30R Instruction Manual

INSTRUCTION MANUAL

3.7 PRE-SELECTING TEMPERATURE

The temperature can be set from -9 °C to 40 °C, in steps of 1 °C.
If the difference between actual and set temperature is more than ±3 °C, the temperature display
will flash.
By pressing the TEMPERATURE key, you can set the temperature. The key
lights up and the current set temperature is displayed.
Set new temperature by rotating the knob and confirm it by pressing on the
knob. The key light turns off and the actual temperature is displayed.
NOTE:
To achieve very low temperatures, it is necessary to appropriately reduce the rotational speed of
the rotor (e.g.: If you set the temperature to -9 °C, you may not be able to use the max. speed of
18,000 RPM, if you want the centrifuge to reach this very low temperature).

3.8 PRE-SELECTING SPEED/RCF

By pressing the SPEED key, you can set the rotational speed (RPM) and centrifugal force
(RCF). The key lights up. By repeated pressings on this key, you select which parameter will
be set. When indicator RPM is lit, you can set the rotational speed, and when indicator RCF is
lit, you can set the centrifugal force. Set new values of both parameters by rotating the knob
and confirm them by pressing on the knob. The key light will then turn off.
• Rotational speed (indicator RPM is lit)
Rotational speed can be set from 200 to 18,000 RPM in steps of
10 RPM.
The maximum rotational speed is automatically set according to the
rotor type in use.
• Relative Centrifugal Force (indicator RCF is lit)
Relative centrifugal force can be set from 5 to 31,150 xg in steps of
10 xg.
Relative centrifugal force is calculated according to the radius of
used rotor, so the minimum and maximum forces are dependent on
the rotor type.
