Frontier Centrifuge FC5707
On each rotor, the maximum load per hole is stated.
ATTENTION:
Do not operate the centrifuge with rotors or buckets which show any signs of corrosion or mechanical
damage.
Do not operate with extremely corrosive substances, which could damage the rotor and buckets.
In case of any questions, please contact the manufacturer!
3.1.3 Loading and overloading of rotors
All approved rotors are listed with their maximum speed and maximum filling weight in "table 1 permissible net
weight" (See APPENDIX).
The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the maximum speed
allowed for this rotor (See label on rotor), must not be exceeded. The liquids the rotors are loaded with should have
a maximum homogeneous density of 1.2 g/ml or less when the rotor is running at maximum speed.
In order to spin liquids with a higher density, the speed has to be reduced according to the following formula:
Reduced speed n = √
red
Example:
1,2
n = √ x 4,000 = 3,360 rpm
red
1,7
In case of any questions, please contact the manufacturer!
3.1.4 Removing the rotor
Untighten the rotor fixing nut completely (screw over the stiff point) and lift the rotor vertically out of the centrifuge.
(See figure 12)
3.2 Power switch
The power switch is located on the back side of the unit (see figure 14).
