Safety instructions
imbalances arise during centrifuging.
• The density of the substance or mixture of sub
-
stances must not exceed 1.2 kg/dm
3
when the
centrifuge is running at maximum speed.
• If unusual noises occur when the centrifuge is
started, the rotor is not secured correctly. In
this case, immediately press "STOP" to stop the
centrifuge.
• While the centrifuge is running, the safety clea
-
rance of 300 mm all around must be kept clear
of persons, objects and hazardous materials.
• In the event of a fault, never reach into the ro
-
tor chamber when the rotor is rotating.
• Pressing the "Cover release" button while the
centrifuge is running opens the cover and trig-
gers a quick stop of the motor. This can lead to
poor centrifuging results.
• While the centrifuge is running, do not move

The
IKA
®
mini G centrifuge is supplied with two
rotors. One rotor is for 1.5 or 2 ml micro-tubes
and one rotor is for 0.2 ml PCR strip tubes.
The rotor for 1.5 or 2 ml micro-tubes allows up
to eight different 1.5 or 2 ml tubes to be centri-
fuged. The adapter supplied for 0.5 ml vessels
also allows up to eight different 0.5 ml tubes to
be centrifuged.
Useful information
The rotor for 0.2 ml PCR strip tubes allows up
to 32 x 0.2 ml PCR strips to be centrifuged.
Both rotors are suitable for applications which
demand relatively low centrifugal accelerati-
on, such as micro-filtration, cell separation and
quick centrifugal separation.
Setting up
• Stand the device at a suitable location and level
it. When setting up the centrifuge, maintain a
safety clearance of 300 mm all around it.
While the centrifuge is running, the safety clea-
rance of 300 mm all around must be kept clear
of persons, objects and hazardous materials.
• Check that the power supply matches the data
on the rating plate.
• Plug the AC adapter into a standard mains so
-
cket in order to supply the device with power.
See the section "Technical data" for the connec-
tion values.
Commissioning

Opening the cover
To open the cover, press the "Release cover" but-
ton (item C).
Closing the cover
Press the cover down manually until it clicks into
place.
Inserting and removing the rotor
Slacken or remove the rotor securing nut (item
A), then place the rotor on the motor shaft. It
must slide on until it reaches a clearly felt stop.
Now secure the rotor by tightening the rotor
nut (finger-tight clockwise). Restrain the rotor by
hand while the nut is being tightened.
Before starting the centrifuge, always check that
the rotor is securely fastened.
Loading the rotor
• The rotor must always be loaded symmetrically,
see Fig. 8.
• Fill the centrifuging vessels before placing them
in the device.
• Do not overfill the centrifuging vessels beyond
the maximum amounts stated by the manufac-
turer.
The cover opens with a damped movement.
The cover should close easily.
To undo the rotor, restrain the rotor by hand and
then unscrew the rotor nut anticlockwise. If the
rotor nut is too tight, a tool (such as a screwdri-
ver) can be used to undo it.
• Take care to fill centrifuging vessels equally so
as to keep the difference in weight between
centrifuging vessels as small as possible. Tare
the centrifuging vessels using scales.

Working with the unit
The AC adapter is suitable for 100 V to 240 V. The
plug adapter for the relevant country must be at-
tached before the AC adapter is plugged into the
mains socket.
The software version appears briefly on the dis-
play, followed by the display test, then an acou-
stic signal sounds. Finally a red dot appears at the
bottom right of the display (stand-by display).
Switching on the device
Press the "Power" button (item H) to switch the
device on.
If the "Power" button (item H) had been used to
switch the device into stand-by mode, the previ-
ous timer value setting is displayed.
Setting the timer
Before the centrifuge can be started by pressing
the "Start/Stop" switch (item D), the timer must
be preset to a value of at least 1 minute. The ma-
ximum setting is 99 minutes. The timer setting
can be adjusted by pressing the respective timer
buttons.
Press the button "1" (item E) to select units of
minutes, press the button "10" (item F) to select
tens of minutes.

Starting the centrifuge
Start the centrifuge by pressing the "Start/ Stop"
button (item D).
Stopping the centrifuge
After the timer period has expired the centrifu-
ge switches itself off automatically and sounds
an acoustic signal. If the cover is not opened, the
acoustic signal sounds three times in quick succes-
sion. The original timer value is displayed again.
Pressing the "Start/Stop" button (item D) during
operation allows the centrifuging process to be
stopped before expiry of the timer period.
Never press the cover release to stop the centri-
fuging process. Doing so opens the cover and
applies heavy braking to the rotor (quick stop).
This can lead to poor centrifuging results and can
adversely affect the working life of the device.
Please note that the device can be started
only once the cover is closed and the timer
value is set to at least 1 minute.
The appliance is maintenance-free.
For cleaning disconnect
the main plug.

Centrifuging vessels
- If a centrifuging vessel leaks or breaks, the frag-
ments of the vessel, splinters of glass and the
centrifuged medium that has escaped must be
fully removed.
- If the medium is an infectious material, the cen-
trifuge must be disinfected immediately.
Liquid in the device
Drainage openings are provided in the base of
the centrifuge so that liquids that have entered
