8.4 Additional care instructions for refrigerated centrifuges
 Empty and clean the condensation water tray regularly. Pull out the condensation water tray to the left
underneath the device.
 Regularly free the rotor chamber from ice formations by thawing, by either leaving the centrifuge lid
open or by performing a short temperature control run at approx. 30 °C.
 To take pressure off the gas spring(s), leave the centrifuge lid open if the centrifuge is not used for a
longer period.
Residual moisture can escape.
 Leave the centrifuge lid open when not in use for a longer period.
Residual moisture can escape. The lid spring is relieved.
 Wipe up the condensation water in the rotor chamber. Use a soft, absorbent cloth for this.
 No later than every 6 months, remove any dust deposits from the ventilation slits of the centrifuge using
a brush or swab. First switch off the device and remove the power plug.
8.5 Cleaning glass breakage
When using glass tubes there is a risk of glass breakage in the rotor chamber. The resulting glass splinters
are swirled around in the rotor chamber during centrifugation and have a sandblasting effect on the rotor
and accessories. The smallest glass particles become lodged in the rubber parts (e.g., the motor guide, the
rotor chamber seal, and the rubber mats of adapters).
Effects of glass breakage in the rotor chamber:
• Fine black metal abrasion in the rotor chamber (in metal rotor chambers)
• The surfaces of the rotor chamber and accessories are scratched.
• The chemical resistance of the rotor chamber is reduced.
• Contamination of samples
• Wear on rubber parts
How to proceed in case of glass breakage
1. Remove all splinters and glass powder from the rotor chamber and accessories.
2. Thoroughly clean the rotor and rotor chamber. Thoroughly clean the bores of the fixed-angle rotors, in
particular.
3. If required, replace the rubber mats and adapters to prevent any further damage.
4. Regularly check the rotor bores for deposits and damage.
NOTICE! Glass breakage in the rotor chamber
Glass tubes in the rotor chamber may break if the g-force is too high. Broken glass can
damage the rotor, accessories and samples.
 Please note the manufacturer's information on the recommended centrifugation
parameters (load and speed).
