Dear users!
Centrifuge CM-50 is easy to use and reliable in operation. We ask you to carefully read the
user manual and follow the instructions for proper operation and maintenance of the CM- 50.
This will insure excellent results and enduring performance.
General information
Centrifuge CM-50 is designed to separate solutions intofractions.
This microprocessor-controlled system provides smooth rotor acceleration and braking during
all segments of the operation. A big graphical display offers instant readout of all the relevant
parameters, including time, braking level and rotor speed (simultaneous RPM and RCF). The
centrifuge lid locks during rotation and unlocks at the end of each run. Adjustable sound
alarm, brightness and sleep mode are also standard. Imbalance detection and a temperature
sensor protect the unit from imbalancing and overheating.

•Unpack the device.
Preparation to work
•Inspect the appearance of the device, the adapter and the power cord for damage.
•Open the lid of the CM-50 with the emergency lid opening lever and remove the packaging
material (see emergency opening of the centrifuge lid p.7).
•In the cold season keep centrifuge at room temperature for at least 2 hours.
•Assembly the rotor.
•Rotor must rotate freely without jamming.
•Centrifuge itself determines and configures to the installed rotor.
•Connect the centrifuge to the adapter and the adapter to the socket.
•Thus, the light indicators will light up.
•In the absence of faults or damage the centrifuge can be considered ready to work.
•In the presence of faults and damage, do not use the centrifuge without consulting a
specialist.
ATTENTION! Network socket must correspond to the adapter plug. In case of non-
compliance with this condition the rules of electrical safety are violated.

Rotor 50.01
Highspeed rotor 50.01 for 12 test tubes
with aerodynamic, hermetic lid.
Maximal rotation speed 15 000 RPM.
Maximal centrifugation force 15 294 RCF.
Applied test tubes:
1) 1.5-2 ml
2) 0.5 ml with adapters
3) 0.2 ml with adapters
Rotor assembly and usage
Assembly: put the rotor on the shaft first and then tighten the nut with a provided hand driven
key.
Usage: always load the rotor symmetrically. By minimizing the difference of weight between the
filled test tubes, you reduce the wear of mechanical parts of the centrifuge. If the overall
imbalance of test tubes exceeds 1 gram, centrifuge will not start, and the display will
show DISBALANCE error code.
Rotor 50.01 must be used with the aerodynamic lid, which securely covers the tubes inside the
rotor, reduces noise level and the heating of test tubes.

Operating centrifuge
Settings adjustments are made using the ''+/- up/down'' keyboard.
Parameters can only be change while the centrifuge is not
running.

red
Rotor icon has a color code.
- Green color means that the lid is opened.
- Red color means the lid is closed and you can now run the
centrifuge.
To run centrifugation just press ''START/STOP'' button.
By reducing the timer to the minimum, you will reach a
''Short run'' mode. This mode allows using ''START/STOP''
button to manage the duration of the spindown.
Centrifuge will run while the button is depressed and will
stop automatically when released.

Cause
Solution
“BLACK
SCREEN”
No main power connection.
Power failure
Check connection of the power cable.
Check if the power supply adapter is
functioning.
THE LID IS
NOT SHUT
Centrifuge lid is left open.
Close and press on the lid till you hear
a click.
DISBALANCE
Total imbalance of test tubes is
more than 1 gram.
Load rotor symmetrically.
PCB
OVERHEAT
Processor Control Board is
overheated.
Give a little time and centrifuge will
cool down automatically.
MOTOR
OVERHEAT
Motor is overheated.
Give a little time and centrifuge will
cool down automatically.
POWER
PROBLEM
Bad connection of ac cord to
adapter, or adapter to
centrifuge. Adapter failure.
Turn off and on the machine with network
switch.
Check all the connections and the power
supply. If necessary, replace the power
supply adapter.
Rotor detection fails.
Centrifuge does not start.
Power supply cuts off.
Imbalance detection failure.
Controller factory settings
mismatch.
For service specialists
only!
Go to “TO” special menu.
Emergency opening of centrifuge lid
To open the lid of centrifuge in case of power failure
or lock damage of the lid it is necessary to raise the
centrifuge and move the lever, which is located on
the bottom of a centrifuge under the control panel, to
the side as it is shown on the figure.

For service specialists
only!
Restoring factory settings
using special ''TO'' menu
When in ''CN'' mode turn the centrifuge off by clicking the
main power switch to ''off'' position.
Press and hold down both buttons (-) and (+).
While holding down the buttons click the power switch to ''on''
position.
Centrifuge will enter to a special service menu ''TO''.
