of exploitation of the machine you can ensure durable and faultless operation.
General information
The centrifuge-mixer CM-70M-07 or CM-70M-09 is a unique combination of high-
speed centrifuge and advanced mixer in one machine. This has become possible
after developing a special control system for the high-performance stepper motor.
Centrifuge features
•Digital timer for centrifugation and mixing.
•Possibility of starting the centrifugation by closing the lid.
•Electronic safety rotor blocking system when the lid is opened during the
centrifugation.
•Memory on board for saving the last used settings of timer, RPM, mixing
and control regime.

•Warranty applies to 24-month period from the date of purchasing.
•Malfunctions arisen through the fault of producer in the course of this period,
are removed free of charge.
•Guaranty is not valid in the following cases:
- If the serial number label of the manufacturer is damaged.
- If damages appear as a result of the incorrect operation, transportation or
storage.
•These documents are necessary if applying for warranty repair:
- User manual with serial number of the machine.
- Officially signed report, describing the reasons and conditions of equipment
malfunction.
•Warranty repair could be performed only if the equipment is delivered in
the original manufacturers packaging or equally safe packaging.
Therefore, please keep the transportation packaging after unpacking the
device.
•If the above warranty requirements are disturbed, repair charges are applied
to the consumer.
For all further questions concerning exploitation and maintenance please
contact manufacturer or product vendor.
Safety features
It is prohibited to:
•Plug the machine in to a power outlet with configuration which differs from the
power adapters’ configuration.
•Plug the power adapter into the outlet if the adapter is damaged.
Transportation and storage
To ensure safety during the transportation, transported equipment should be
packed in the original manufacturers’ packaging or similar packaging
substitute.
Equipment can be transported by any kind of closed transport so that
equipment is tightly fixed, and transportation runs accordingly to regulations
applied to this way of transport. Equipment should be stored in original
manufacturers packaging in dry room with humidity not more than 80% and
temperature range from +10 C up to +40 C.
It is not recommended to store the equipment more than 36 month.

Main components
Centrifuge-mixer consists of casing, transparent lid, rotor and rotor safety shield.
Control panel on the front and network switch in the back. Under the lid is mixing
control button “MIX”.
Timer setting button allows to select duration of centrifugation or mixing.
When the lid is opened, RPM setting button allows selecting the desired
centrifugation speed, when the lid is shut (with indicator glowing) it starts the
centrifugation or stops before the set time runs out. Mix setting button allows to
select the mixing density. RPM, timer and mixing parameter indicators are
indicating selected timer, rpm and mixing regime settings. Rotor is fixed on the
motor by a nut and protected by the transparent safety shield. While centrifugation
the rotor is covered by the lid. On the lid is a special lid sensor magnet is placed.

Using the centrifuge
! - For setting and modifying the centrifuge parameters the lid should be
opened.
1. Setting centrifugation regimes
Centrifugation speed of centrifuge is selected by pressing the button with
opened lid.
When the indicator is blinking centrifugation starts automatically after closing the
lid.
When the indicator is lighting constantly centrifugation starts by pressing the
button.
2. Stopping the centrifugation
Centrifuge starts and stops by pressing the button or automatically if the timer
setting is achieved.
! –NOTICE: If the lid of the centrifuge has been opened during the
centrifugation the rotor will automatically stop by the electronic lock system
within approx. 0.5 sec. This is not recommended for normal use since the
braking time is too short and it could be too aggressive for some samples.
Using timer
Setting times should be performed while the rotor is stopped by pressing the timer
setting button.Using vortexing mode
! - Using the vortex regime, the lid of the centrifuge-mixer should be opened.
1. Vortexing begins when the mix button is pressed.
2. Vortex regime density can be changed by pressing the mix setting button.
3. Vortexing stops either when the timer program is over or by pressing “MIX”
button again.
! - Notice: It is recommended to use the “MIX” mode for duration not
exceeding 5 minutes. Then a 5-minute break is needed to cool down the
motor.
Operation tips
! - When the centrifuge is not used it is not needed to unplug the power adapter
from the power outlet, except for the case when it is planned not to use the
machine for a long period of time.
! - Disbalanced rotor loading, high room temperature or long use of High
intensity vortexing may cause the motor overheating. In this case centrifuge-
vortex will stop any kind of operation, give an acoustic alarm of 10 short beeps
and will automatically switch to cool down regime. All the indicators will start to
blink. If during 3 minutes the machine will not cool down to normal temperature
it will repeat the acoustic alarm and indicators will continue to blink until the
normal temperature regime is regained.
Using programmable sample preparation mode (SP)
SP –Is a special highly effective regime for preparing samples for PCR and other
applications and mixing hardly dissolving samples. During this programmable
regime samples are being vortexed with variable intensity for 3 seconds and
then centrifuged for 7 seconds with optimal 2000 RPM (260 RCF) for washing
samples down from the ages of the tube.
Vortexing intensity could be changed either before or while the program is
running by pressing mix setting button. The overall duration of the program can
be selected by the timer setting button.
! –Notice: Selecting SP regime and changing timer parameters should be
performed while the lead is opened.
To start running SP program mode shut the lead and press button or
just shut the lid if the SP indicator is blinking.
