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.
Removing and Installing the Angle Rotor
The Spectrafuge 24D 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.
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.
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. One typical balancing scheme is shown in Figure 1.
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 measured 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 tothe rotor and centrifuge. The revised maximum speed can be calculated with the following formula:

Example:
Where the density of the liquid is 1.7, the new maximum speed would be calculated as follows:
If in doubt concerning maximum speeds, please contact the manufacturer for assistance.
Operating Instructions
CAUTION: 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.
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 the rotor lid snaps securely into place, by pressing down on center catch.
Closing the Lid
Close the centrifuge lid. This microcentrifuge has a lid lock that activates only when a run is started.
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.
CAUTION: 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.
- Disconnect the power cord from the wall socket.
- Remove the plastic plug, located on the left side of the unit.
- Pull the wire (attached to the plug) to open the lid lock manually.
Lid Lock
The centrifuge can be started only when the lid is securely closed. When a run is started, the lid lock automatically activates.
CAUTION: 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.
Speed Selection
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. Rpm or g-force display is set by pressing the knob. Turn the knob to increase or decrease the value.
Selection of Operating Time, Momentary Operation, Start/Stop
Operating time can be selected from 0.5 min. to 30 min. by turning the timer knob on the left. The time can be set in 0.5-minute increments from 0 to 10 minutes and in 1-minute increments from 10 to 30 minutes. After 30 minutes, the display shows “–” which indicates continuous run. In this mode, the centrifuge will run until manually stopped. To start a run, press the timer knob.
When the preselected time expires, the centrifuge will stop automatically. To stop the centrifuge prior to the expiration of set time, press the timer knob. The centrifuge may be operated for a short run by pressing and holding the timer knob. The centrifuge will continue to run as long as the timer knob is depressed, the time (in seconds) will count up on the time display.

Service and Maintenance
Centrifuge Service
The brushless motor in this 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.
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.
Replacing Fuses
Check the fuse when it is recommended (see Troubleshooting Guide section). Disconnect the power cord from the wall socket before checking the fuses. The fuse holder is located in the power inlet on the rear of the unit. 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. See Specifications section for information on fuse type.

Should you have a question about the operation of the Labnet Spectrafuge™ 24D Microcentrifuge or if service is required, contact Corning Customer Service. Labnet C2400 Spectrafuge 24D Microcentrifuge. Do not send in a unit for service without first calling to obtain a repair authorization number. Should the unit require service return, it should be properly packed to avoid damage. Any damage resulting from improper packaging shall be the responsibility of the user
Determination of G-values
The centrifuging radius of the 1.5/2.0 mL rotor is 8.23 cm. The Labnet Spectrafuge™ 24D Microcentrifuge has an automatic g-force conversion program, so g-values 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 below can be used to manually determine g-values for any centrifuging radius.

To calculate the RCF value at any point along the tube or bottle, Labnet C2400 Spectrafuge 24D Microcentrifuge measure the radius (in mm), from the center of the centrifuge spindle to the particular point. Draw a line from the radius value on the right-hand column to the appropriate centrifuge speed on the lefthand column. The RCF value is the point where the line crosses the center column. The nomogram is based on the formula: RCF = (11/17 x 10-7) RN2 where: R = Radius in mm from centrifuge spindle to point in tube bottom N = Speed of spindle in RPM
