1 Application
Centrifuges are used for separation samples taken from people’s, animal’s and plant’s components of different densi-
ties, under the influence of the centrifugal force, to provide information about their biological state (C0336 – ventilated,
C0336R– with cooling).
Its construction ensures easy operation, safe work and wide range of applications at laboratories engaged in routine
medical analyses, biochemical research works etc.
This centrifuge is not biotight and therefore during centrifugation of preparations requiring biotightness one has to
use closed and sealed containers and rotors. In the centrifuge, it is prohibited to centrifuge caustic, inflammable and
explosive preparations.

5.7 Safety features
Cover lock
The centrifuge can be started only with properly closed cover. While, the cover can be opened only after stop-
ping the rotor. In case of emergency opening of the cover during operation, the centrifuge will be immediately
switched-off and the rotor will brake till complete stopping.
Unbalance detecting
When loads of opposite buckets or carriers in rotors are unbalanced, the drive will be switched-off during accelera-
tion or operation of the centrifuge – and the error message will be displayed.
Rotor verification and checking compatibility with loaded program
Directly after starting centrifuging, a unit verifies the type of the rotor applied and in the case of its incompatibility
with the type indicated in the application or absence of the rotor, the spinning process shall be stopped with
simultaneous displaying the error message. The conformity of the type of the rotor is signaled with a single audible
signal. In case auto identification (see 9.8 Other) option is checked, proper rotor will be automatically chosen,
without user engagement.
Rest state inspection
Opening of the centrifuge’s cover is possible only with the rotor in the state of rest. When the rotor is being
stopped, the STOP diode is on and goes off when it is stopped. (Excepting emergency cover opening) – see p.
TROUBLESHOOTING.
Checking of excessive temperature
If temperature in rotation chamber exceeds 50°C (C0336) / 65°C (C0336R) caused by, for example, malfunction
of cooling system, drive will be switched off and error message will be displayed. The reboot is only possible after
chilling device.
5.8 Increase in temperature (C0336 only)
In uncooled centrifuges, the temperature in the rotor chamber, rotor and sample can increase to above 40°C,
based on the run time, g-force (RCF)/speed and ambient temperature.
6 Centrifuging

6.3 Centrifuging notes
• Connect the centrifuge to the mains (master switch on left side of the centrifuge).
• Open the cover of the centrifuge by pressing the COVER key. Prior to putting the rotor in, one has to check if
the rotating chamber is free of impurities, e.g. such as dust, glass splinters, residues of fluids that must be taken
away.
• One shall fit the rotor on the motor shaft driving it home on the cone.
Fitting the rotor too shallow will result in lack of identification of the rotor after start of the centrifuge,
displaying the error message and stopping the centrifuge.
• Screw-in the bolt for fixing the rotor (clockwise) and screw it tightly home with the supplied spanner for the rotor.
• Swing-out rotors have to be provided with the buckets in all seats. One should remember that every buckets
swings individually. Bucket suspension studs should be lubricated periodically with petroleum jelly.
• In case of rotors designed with the cover they must not be used without it. Rotor covers must be closed exactly.
Rotor covers ensure smaller drags of the rotors, proper setting of the test-tubes and airtight sealing.
• One should use only buckets intended for selected types of the rotor.
• Fill test tubes outside the centrifuge.
• Put on or screw the caps on vessels and rotors (if applicable).
• In case of centrifuging in an angle rotor, test tubes (buckets) have to be filled properly in order to avoid overflows.
Centrifuge will tolerate small weight differences occurring during loading of rotors. However, it is
recommended to equalize vessels loads as much as possible in order to ensure minimal vibrations
during operation. When the centrifuge is started with large imbalance, the unbalance control system
will switch-off the drive system and error signal will be transmitted. On the monitoring panel, error
message will be displayed.
• In order to prolong lifetime of the gaskets and threaded parts shall be lubricated with the petroleum jelly
• For replacement of the rotor one shall unscrew clamping and then grab the rotor with both hands at opposite
sides, taking it away from drive shaft by pulling it up.

In the first moment, the EXIT field is marked (the message is blinking). Pressing the SET key will cause returning
to the PROG → CURVES fold, without making changes in the acceleration characteristics.
„1” SECTION
After setting the time the device will proceed to setting the speed of the given section of characteristics (the set
value TIME + SPEED blinks). With UP and DOWN keys one should set the speed value and press the SET key.
The set speed value is limited by the maximum speed of the rotor connected with the edited program.
After the end of programming the speed, the graphical displaying of the section (of all sections) will occur
TIME+SPEED of the user’s acceleration characteristics.
After programming the section 1, there is a possibility to program the next section, number 2:
„2” SECTION
Programming of new section possible (the whole line 2 is blinking).
Programming as in the case of section 1. It is possible also to
abandon the programming: with UP/DOWN keys choose the OK
option (it will blink) and save (press the SET) only the accelera-
tion characteristics of 1 section with TIME/SPEED parameters
described in the line 1.
The minimal speed of the next section of acceleration characteristics is equal to the speed of the already
programmed previous section.
„3” SECTION

Programming of new section possible (the whole line 3 is blinking).
Programming as in the case of section 1. It is possible also to
abandon the programming: with UP/DOWN keys choose the EXIT
option (it will blink) and save (press the SET) only the accelera-
tion characteristics of 2 section with TIME/SPEED parameters
described in the line 1 and 2.
„4” SECTION
Programming of new section possible (the whole line 4 is blink-
ing). Programming as in the case of section 1. It is possible also
to abandon the programming: with ▲▼ keys choose the OK
option (it will blink) and save (press the SET) only the accelera-
tion characteristics of 3 section with TIME/SPEED parameters
described in the line 1, 2 and 3.
Repeated attempt to program already programmed sections of the acceleration characteristics will cause beginning
of programming of the whole acceleration characteristics once again (with settings of the program loaded to edition.
Deceleration characteristic PROG / CURVES / DECELERATION
After choosing CONFIG → CURVES → DECELERATION the window of the characteristics wizard will be displayed:
Default deceleration characteristics connected with the loaded program will be displayed on the screen.
Creating of deceleration characteristics takes place a little differently than acceleration characteristics
NO. section no. (max. 4)
TIME total acceleration time
SPEED final RPM
DEC:10 characteristic’s no. (10-19)
In the first moment, the EXIT field is marked (the message is blinking). Pressing the SET key will cause returning
to the PROG → CURVES, without making changes in the deceleration characteristics.
„1” SECTION

Centrifuge user manual | 15
To edit the deceleration characteristics, one should mark the section of characteristics with ▲▼ key (the whole
TIME+SPEED line will begin to blink; at this stage, it is only one section, with the number 1) and then press the
SET key. The device will proceed to setting the characteristics’ section time (only the set TIME value is blinking).
With ▲▼ keys, one should set the required time value and press the SET key.
In order to compete the creation of the deceleration curve it is necessary for the speed of the last of
programmed sections of the curve to be equal = 0. Otherwise the curves wizard will not enable the end
of programming (it will be impossible to select the OK option).
After programming the section 1, there is a possibility to program the next section, number 2:
„2” SECTION
New section programming possible (the whole line 2 is blinking).
Programming as in the case of the section 1. To stop creating the
deceleration curve at the stage of two sections, it is necessary to
set the speed in section 2 to 0 and press the SET key.
The maximum speed of the next section of deceleration characteristic is equal to the speed programmed
already of the previous section.
„3” SECTION
New section programming possible (the whole line 3 is blinking).
Programming as in the case of the section 1. To stop creating the
deceleration curve at the stage of three sections, it is necessary
to set the speed in section 3 to 0 and press the SET key.
„4” SECTION
New section programming possible (the whole line 4 is blinking).
Programming as in the case of the section 1. If speed of the last
section=0, it is possible to save the created characteristics by
choosing the OK option with ▲▼ keys and pressing the SET key.
Repeated attempt to program already programmed sections of the acceleration characteristics will cause
beginning of programming of the whole deceleration characteristics once again (with settings of the
program loaded to edition).
6.6 Programs with user characteristics
Loading a modified program in the CURVES fold is signaled by the icon on the main screen:
Icon signals that program with user acceleration/deceleration
characteristics are loaded.
It is not possible to change parameters (speed, rotor no. and others) during run, when program with user charac-
teristic is loaded. Changing these parameters is possible in PARAM/ ACCELERATION, PARAM/DECELERATION.
6.7 Choosing rotors
Loading a modified program in the CURVES fold is signaled by the icon on the main screen:
• Press SET.
• With ▲▼◄► keys mark 11199 / ––––– zone.
• Press SET.
• With ▲▼ keys mark choose demanded rotor.
