6.2 Rotor Maintenance
The rotor should be cleaned thoroughly after each use. 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.
6.3 Removing and Installing the Angle Rotor
The Prism™ Microcentrifuge comes complete with a standard 24-place rotor installed. To remove
the rotor for cleaning, remove the rotor securing screw from the motor shaft by turning the screw
counterclockwise, using the rotor wrench. Lift the rotor directly upward in a straight vertical motion.
Figure 1. Loading the rotor to achieve balance
To replace 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.
6.4 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 that there is equal spacing between all
tubes. One or two additional loaded tubes may need to be added to achieve this. Refer to Figure 1. to see
one typical balancing scheme.
6.5 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 1.2g/ml or less. In order to centrifuge liquids with a higher density
it is necessary to reduce the speed. 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) = × 15,000 = 12,602 rpm
If in doubt concerning maximum speeds, please contact the manufacturer for assistance.

7.0 Operation
ATTENTION: Never attempt to operate the centrifuge with rotors or adapters that show signs of
corrosion or mechanical damage. Never centrifuge strongly corrosive materials that may damage the
rotors, accessories, or bowl of the unit.
7.1 Attaching Rotor Lid
After the rotor has been properly secured and loaded, attach the rotor lid to the rotor. Always use the
rotor lid for safety and to allow the rotor to reach proper speed. Make sure that the rotor lid snaps
securely into place, by pressing down on center catch.
7.2 Closing the Lid
Close the centrifuge lid. The Prism™ Microcentrifuge has a lid lock that activates only when a run is started.
7.3 Lid Release
The lid will remain locked during a centrifuge run. Once the run has been completed and the rotor has
come to a stop, a beep will indicate the end of a run, and the lid will unlock automatically.
WARNING: Do not attempt to open the lid of any centrifuge until the rotor has come to a complete stop.
In the event of a power failure or malfunction, it may be necessary to open the lid manually.
1. Disconnect the power cord from the wall socket.
2. Remove the plastic plug, located on the left side of the unit.
3. Pull the wire (attached to the plug) to open the lid lock manually.
7.4 Lid Lock
The centrifuge can be started only with the lid securely closed. When a run is started, the lid lock
automatically activates. Do not attempt to open the lid during a centrifuge run. At the end of the
run, the lid will automatically unlock. Never attempt to override the lid lock mechanism. Doing so is
dangerous and could damage the centrifuge.
7.5 Speed Selection
Figure 2. Prism Microcentrifuge control panel layout
The speed (rpm or g-force) can be selected from 500 to 15,000 rpm in 100 rpm increments or from
100 to 21,200 x g with the control knob. The speed is selected by pressing the RPM or RCF button. The
speed signal will begin to blink. Then, turn the control knob to increase or decrease the value.

6| LABNET PRISM MICROCENTRIFUGE
7.6 Selection of Operating Time, Momentary Operation, Start/Stop
Operating time can be selected from 0.5 min to 99 min by pressing the TIME button and adjusting with
the control knob. The time can be set in 0.5 minute increments from 0 to 10 minutes and in 1 minute
increments from 10 to 99 minutes. After 99 minutes, the display shows “--” which indicates continuous
run. In this mode, the centrifuge will run until manually stopped. To start a run, press the control knob.
When the preselected time expires, the centrifuge will stop automatically. To stop the centrifuge prior
to the expiration of set time, press the control knob. The centrifuge may be operated for a short run by
pressing and holding the control knob. The centrifuge will continue to run as long as the control knob is
depressed and the time, in seconds will count up on the time display.
8.0 Service and Maintenance
8.1 Centrifuge Service
The brushless motor in the Prism™ Microcentrifuge requires no routine maintenance. Any required
service should be performed by authorized, qualified personnel only. Repairs performed by unauthorized
personnel may void the warranty.
8.2 Cleaning
Always keep the centrifuge housing, rotor chamber, rotor and rotor accessories clean. All parts should be
wiped down periodically with a soft cloth. For more thorough cleaning, use a neutral cleaning agent (pH
between 6 and 8) applied with a soft cloth. Excessive amounts of liquid should be avoided. Liquid should
not come into contact with the motor. After cleaning, ensure that all parts are dried thoroughly by hand
or in a warm air cabinet (maximum temperature 50°C).
The rotor should be cleaned after each use. When spinning samples containing phenol or phenol
chloroform, the rotor should be cleaned immediately after use.
Should a spill of infectious materials occur within the rotor or chamber, the unit should be disinfected.
This should be performed by qualified personnel with proper protective equipment.
8.3 Replacing Fuses
Check the fuse when it is recommended in the Troubleshooting Guide located in this manual. The fuse
holder is located in the power inlet on the rear of the unit. Disconnect the power cord from the power
inlet. Open the fuse holder drawer by inserting a small screwdriver under the tab and prying it open.
Remove the innermost (operative) fuse from its retaining tabs and replace the fuse if necessary. A spare
fuse is located in the outermost chamber of the fuse drawer. Replace only with a fuse of exactly the
same value as the original. Fuse type may be found in the Technical data section of this manual.
