5.0 Installation
The centrifuge should be installed on a rigid, even surface such as a stable laboratory bench, countertop, etc. To guarantee
sufficient ventilation, ensure that the centrifuge has at least 12 inches (30 cm) of free space on all sides, including the rear. The
centrifuge should not be located in areas subject to excessive heat such as in direct sunlight or near radiators or the exhaust of a
compressor, as a buildup of heat may occur within the chamber.
Before operating the centrifuge, check that the power source (electrical outlet on the wall) corresponds to that on the
manufacturer’s rating label, then connect the power cord to the centrifuge and the power source.
6.0 Installation of Rotors and Rotor Maintenance
6.1 Rotor Maintenance
The rotor should be cleaned thoroughly after each use. NOTE: Thorough cleaning must be performed when spinning samples
containing phenol or phenol chloroform. Periodically inspect the rotor for dents, dings, scratches, discoloration, and cracks. If any
damage to the rotor is found, discontinue use of the rotor immediately and replace.
6.2 Removing and Installing the Rotor
The Labnet Prism™ R refrigerated microcentrifuge comes complete with a standard 24-place rotor installed. To remove the rotor for
cleaning, using the rotor wrench remove the rotor securing screw from the motor shaft by turning the screw counterclockwise. Lift
the rotor directly upward in a straight vertical motion.

Instruction Manual | 3
Securing
screw
Figure 1. Loading the rotor to achieve balance.
To replace the rotor, first make sure the motor shaft and rotor mounting hole are clean. Place the rotor on the motor shaft.
Reinstall the rotor securing screw on the motor shaft by turning it clockwise. Hold the rotor with one hand and tighten the rotor
securing screw, using the rotor wrench.
6.3 Loading the Rotor
Tubes to be loaded should be filled equally by eye. The difference in the weight between the tubes should not exceed 0.1 gram. Tubes
should always be loaded so there is equal spacing between all tubes. One or two additional loaded tubes may need to be added to
achieve this. See Figure 1 for a typical balancing scheme.
6.4 Overloading Rotors
The maximum load of the rotor and maximum speed has been established by the manufacturer. Do not attempt to exceed these
values. The maximum speed of the rotor has been established for liquids having a homogeneous density of 1.2 g/mL or less. In order
to centrifuge liquids with a higher density it is necessary to reduce the speed. NOTE: Failure to reduce the speed may result in damage
to the rotor and centrifuge. The revised maximum speed can be calculated with the following formula:
1.2
higher density value
Reduced speed (n
red) = × max. speed (nmax)
1.2
1.7
(nred) = × 15,000 = 12,602 rpm
Example: Where the density of the liquid is 1.7, the new maximum speed would be calculated as follows:
1.2
higher density value
Reduced speed (nred) = × max. speed (nmax)
1.2
1.7
(nred) = × 13,500 = 11,342 rpm
If in doubt concerning maximum speeds, please contact the manufacturer for assistance.
