3.2 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.
3.3 Removing and installing the angle rotor
The Prism 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.
3.4 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.
3.5 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:
Reduced speed (n
) = x max speed (n
red
max
)
Example:
Where the density of the liquid is 1.7, the new maximum speed would be calculated as
follows:
= x 15,000 = 12,602 rpm
n
red
If in doubt concerning maximum speeds, please contact the manufacturer for assistance.
4. 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.
4.1 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.
4.2 Closing the lid
Close the centrifuge lid. The Prism has a lid lock that activates only when a run is
started.
4.3 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.
4.4 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.
4.5 Speed selection (see Figure 2.)
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.
4.6 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.
5. Service and Maintenance
5.1 Centrifuge service
The brushless motor in the Prism requires no routine maintenance. Any required service
should be performed by authorized, qualified personnel only. Repairs performed by
unauthorized personnel may void the warranty.
5.2 Cleaning the centrifuge
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 50ºC)
Figure 2. Prism control panel layout
5.3 Cleaning the rotor
The rotor should be cleaned after each use. When spinning samples containing phenol or
phenol chloroform, the rotor should be cleaned immediately after use.
5.4 Disinfection
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.
5.5 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
