Introduction

Dear users!
Centrifuge CM-50 is easy to use and reliable in operation. We ask you to carefully read the
user manual and observe all the requirements of the maintenance and operation this will
ensure a long and flawless exploitation of the device.
General information
CM-50 is a unique high-speed centrifuge designed to separate solutions into fractions.
The device is used in analytical chemistry, microbiology, virology, clinical biochemistry, etc.
Microprocessor control system provides smoothness of rotor rotation start, task enterring and
parameter reflection on the displays (time, braking level, rotor rotation speed in RPM or RCF
units), blocking of lid during work, sound alarm and signals, sleep mode and automatic lid
unblocking at the end of work. Built-in temperature and imbalance sensors protect the unit
from overheating and dangerous imbalance.

Rotor assembly and usage
3
Highspeed rotor 50.01 for 12 test tubes
with aerodynamic, hermetic lid.
Maximal rotation speed 15 000 rpm.
Maximal centrifugation force 15 000 rcf.
5 braking levels.
PUSH mode is valid.
Applied rotor
Rotor assembly and usage
Assembly: put the rotor on the axis, note that the pins of the axis must get into the grooves of
the rotor, then tighten the rotor nut with special 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
ER_db - imbalance error code.
Rotor 50.01 must be used with the aerodynamic, magnetic lid which seals the contents of the
rotor, reduces noise level and the heating of test tubes.

Preparation to work
• Unpack the centrifuge.
• Inspect the appearance of the device, the adapter and the power cord for damage.
• Open the lid of the centrifuge with the emergency lid opening lever and remove the
packaging material (see emergency opening of the centrifuge lid pg.7).
• In the cold season keep centrifuge at room temperature for at least 2 hours.
• Assembly the rotor it must rotate freely without jamming.
• Connect the centrifuge to the adapter and the adapter to the socket.
• The light indicators will light up.
• In the absence of faults or damage the centrifuge can be considered ready to work.
ATTENTION! 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.

Control description
On the front side of the centrifuge the control panel is situated with indicators and buttons that
have the following functions:
Control description
- Increasing parameter / lid opening button.
- Decreasing parameter / starting and stopping button.
- Setting timer.
- Setting braking level.
- Setting speed.
ATTENTION! To change the PRM to G (RCF), or vice versa,
Press and hold button for 5 seconds.

Operation

Operation
Settings and adjustments of the parameters of the centrifuge are made on the turned on device with
opened or closed lid. Do not forget to use the aerodynamic, magnetic lid with the rotor.
During operation parameter adjustments are not possible.
Braking levels (15000 rpm, full rotor)

2....................................................................................................................20
3....................................................................................................................15
4....................................................................................................................13
5....................................................................................................................11
When all the parameters are entered to start the centrifuge close the lid and press the button.
If the settings were made with the lid closed then press the last set parameter button
, or and press the button.
Thus the centrifuge will start and the timer will begin the countdown. Last minute of countdown is displayed
in seconds. When the set time runs out centrifuge stops, alarms sounds and lid unblocks.
Centrifuge СМ-50 supports a special PUSH mode to make your work more effective
and a sleep mode to minimize power consumption.
PUSH mode is in the speed range before 1 or after 15. Duration of centrifugation in PUSH mode is
determined by the duration of button retention period, as soon as the button is released,
the centrifuge stops with the set the braking level.
SLEEP mode - device goes into sleep mode automatically after 25 minutes of standstill.
To exit sleep mode, just press any button.
ATTENTION! Do not forget to use the magnetic aerodynamic lid with the rotor!
1. Setting speed parameter:
Press the button and set the desired parameter value with buttons.
2. Setting time parameter:
Press the button and set the desired parameter value with buttons.
3. Setting brake level parameter:
Press the button and set the desired parameter value with buttons.

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 to 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.
