2. Installation
2.1 Unpacking the centrifuge
Before unpacking the centrifuge, inspect the outside of the carton for any shipping
damage.
The centrifuge is delivered in a carton with protective foam cushioning. Remove the
centrifuge from the carton. Retain thecarton and cushioning until it has been established
that the centrifuge is working properly.
Inspect the centrifuge for any visible signs of shipping damage. Shipping damage is the
responsibility of the transportation carrier. Any claims for damage must be filed within
48 hours with the carrier that delivered the centrifuge.
The accessories supplied with the centrifuge should be kept with the instruction manual
near the centrifuge’s place of installation.
2.2 Required space
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 15cm (6 inches) 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.
2.3 Installation
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.

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 Spectrafuge 24D 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. 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.

Figure 1. Loading the rotor to achieve balance
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 the maximum speed have 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

) =
Example:
Where the density of the liquid is 1.7, the new maximum speed would be calculated as
follows:

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 Spectrafuge 24D 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 13,300 rpm in 100 rpm
increments or from 100 to 16,300 x g with the knob on the right. “g-force” or “rpm”

5. Service and Maintenance
5.1 Centrifuge service
The brushless motor in the Spectrafuge 24D 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)
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 Technical data section of this manual.)

8. Determination of g-values
The centrifuging radius of the 1.5/2.0ml rotor is 8.23cm. The Spectrafuge 24D has an automatic
g-force conversion program, so gvalues are automatically calculated and can be displayed on the
control panel, for this centrifuging radius. If adapters or smaller tubes are used, the centrifuging
radius changes as does the g force. The chart on the next page can be used to manually determine
g-values for any centrifuging radius.
8
e
To use this chart, find the radius value on the radius scale. Place the edge of a ruler on
the value. Place the right side edge of the ruler on the speed scale at the desired speed.
The estimated RCF can then be read from the RCF scale where the ruler edge passes
through it. This chart can also be used to determine the proper speed for the desired
RCF value.
