5. Description of the centrifuge
The centrifuge LC 6 is a table-top centrifuge with horizontal rotor designed for continuous operation.
The horizontal rotor contained in the standard delivery schedule and the tube holders can
accommodate up to 6 specimen tubes. The special horizontal rotor facilitates a fast and simple
specimen charge and complete horizontal separation.
A lid safety switch prevents the centrifuge from operating when the lid is open. The yellow “LATCH”
indicator at the front of the centrifuge lights up as soon as the lid has been correctly locked. In
addition to the lid safety switch, the LC 6 is equipped with a “0 rpm” lid locking system. This safety
system keeps the lid closed at all times (even in the event of a power failure) and ensures that the lid
can be unlocked only when the rotor has come to a standstill.

•The control elements are shown in Section 7.
For safety reasons, the locking system is always activated.
•The user can switch it off for approx. 15 seconds by pressing the
“OPEN/(EMERGENCY STOP)“ button briefly. This is possible only with the
centrifuge switched on and the rotor at a standstill.
•At the end of a centrifugation, the lid is automatically unlocked for approx. 60
seconds.
In order to exclude transport damage and to check correct installation, carry out a test run when
starting up the centrifuge.
Procedure:
•Connect centrifuge with the power cord to the power supply.
•Press “OPEN/(EMERGENCY STOP)“ 0 button.
•“UNLOCKED“ display lights up.
•Turn lid knob in counterclockwise direction and open lid.
•There should be no foreign bodies in the rotor chamber.
•Turn rotor by hand and check whether it runs freely and horizontally and that the screw in the
middle of the rotor is tightened firmly. If this is not the case, the centrifuge must not be put into
operation.
•Insert empty tube holder into the rotor and check that it is fitted correctly.
•The rotor must be loaded evenly.
•Close lid and turn lid knob in clockwise direction to end position.
•“LATCH“ display lights up.
•The centrifuge will only start running if the lid has been closed correctly.
•Press “START“ button and perform a test run.
•“RUN“ display lights up.

Press the “OPEN/(EMERGENCY STOP)“ button 3 times until all display lights have
stopped flashing and are off, to confirm the set time.
Recommended conditions for centrifugation of S-Monovettes with gel preparation:
ØTube holder 100 mm
ØSerum-gel g-force 2,000 x g (= fix set) / 15 min / 20 °C
(within 4 hours after blood collection)
ØLi-Hep-gel g-force 2,000 x g (= fix set) / 20 min / 20 °C
(within 4 hours after blood collection)
Concerning centrifugation conditions for other type of blood collection tubes refer to data provided
by manufacturers.
Counter
The cycle counter keeps a count of the total number of machine runsfor servicing and maintenance
records. The counter is located at the lower front side.
Access to the Rotor Chamber during a Power Failure
In the event of a power failure, it may be impossible to unlock
the lid in the usual manner. If this happens, you can gain access
to the rotor chamber by removing the label in front of the lid lock
and manually deactivating the locking mechanism with a pen
(see illustration). Pull the mechanism in the direction of the
control panel, unlock it and open the lid. Then re-stick the label
in position.
If the centrifuge is damaged, have it checked by a technician before further use!
Loading the Rotor
The centrifuge must be evenly loaded for it to function properly.
To ensure even loading, comply with the following rules when loading the horizontal rotor for
six tube holders: •Opposite-located tube holders must be identical.
•Opposite-located tube holders must either be empty or loaded with the same
number of samples of the same weight.
•When centrifuging an uneven number of samples, insert a tube filled with
water as a counterbalance.
Centrifuging
If a problem occurs during operation which makes it necessary to switch off the
centrifuge, push the “OPEN/(EMERGENCY STOP)“ button immediately.
Procedure:
•Press “OPEN/(EMERGENCY STOP)“ button to unlock the lid and open lid.
•Insert specimen tubes in the tube holders. Make sure they are evenly loaded.

Operating Instruction Centrifuge LC 6
page E-12 V. 2.1.2 / 01/2009
•Close lid and turn lid knob to end position in clockwise direction. The “LATCH“ display lights
up in order to show correct interlocking.
•If the lid knob is not snapped in completely, the “LATCH“ display will not light up and it will
not be possible to put the centrifuge into operation.
•Press the “START“ button.
•The rotor will start to turn. The “RUN“ display lights up.
•At the end of the running time the “RUN“ display goes out and the rotor break is applied
until it comes to a complete standstill.
•The “UNLOCKED“ display lights up; the interlocking mechanism is deactivated thereby
facilitating access to the rotor chamber. After expiry of the automatic unlocking time the lid
can be unlocked with idling rotor using the “OPEN/(EMERGENCY STOP)“ button.
•Turn lid knob in an anticlockwise direction and open lid.
•Remove specimens.
•The centrifuge can be put into operation immediately again.

Cleaning
Potential danger of contamination
The regulations for cleaning the device must be observed. Inattentive cleaning
or non-observance of the regulations can cause malfunctions!
•Disconnect the device from the mains supply before cleaning.
•Disinfect the apparatus before cleaning
•No liquid may be permitted to enter the device during cleaning.
•Clean the housing surfaces with a damp cloth. A soap solution may be used.
Carefully dry the device after cleaning.
•Do not use scouring agents or aggressive cleaning liquids or solutions (except
alcohol) under any circumstances.
•Isopropanol may be used in case of severe soiling.
•Fully/partially halogenated hydrocarbons, ketones, esters, and other chemical
not specified by the manufacturer may damage the rotor and tube holders and
may not be used.
Example for a disinfectant:
The following aqueous solution can be used as a disinfectant:
25 g ethanol 96 %, 35 g 1-propanol, 0,1 g glyoxal ad 100 g aqua dest.
Apply the solution, and allow it to react for a few minutes, depending on the
contamination. If necessary, repeat the application of disinfectant.
Tubeholder: Small glass particlesfrom a tube breakage remaining in the tube holder can stick to
the next sample tube inserted in this holder. When handling this tube, the broken glass
can penetrate protective gloves and cause injury from cuts to the user’s fingers or
hand. Broken glass remaining can result in stress points with subsequent tubes
causing further breakage. If a tube breaks, remove it carefully from the tube holder.
Dispose of the sample and tube fragments correctly, and clean both the inside and
outside of the tube holder. If necessary use a new rubber adapter and reinsert the
tube holder in the rotor.
Regular Maintenance
It is recommended, depending on the amount of use and the external conditions, that
the rated speed and the electrical safety be checked every 1-2 years to ensure
continuing safe operation.
It is recommended that the rotor chamber be cleaned every 6 months or if a tube
breaks.
It is to replace the tube holders after 5,000 machine runs or the latest after 24 months
of use.
