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. Smallest glass particles become lodged in the rubber parts (e.g.,
the motor sleeve, the rotor chamber seal, and the rubber mats of adapters).
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).
Effects of glass breakage in the rotor chamber:
• Fine black metal abrasion dust in the rotor chamber (in metal rotor bowls).
• 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. Regularly check the rotor bores for deposits and damage.
1. Remove the sealing ring to thoroughly clean the groove below it.
2. Clean and disinfect the rotor lid using the recommended
cleaning agents.
3. Rinse the rotor lid thoroughly with distilled water.
4. Moisten the new sealing ring with clean water.
5. Insert the sealing ring in the clean groove of the rotor lid.
6. Press the sealing ring into the lateral groove, around the entire
circumference of the rotor lid.
7. Place the rotor lid with the underside facing upwards on a cloth.
8. Leave the rotor lid to dry for 5 –10 minutes.
9. Perform a visual inspection.
The seal must be flush with the groove of the rotor lid around the
entire circumference and must not protrude at any point.
10. Fit the rotor lid on the rotor.
11. Leave the rotor lid open when the rotor is not being used.
The rotor lid cannot close properly if the sealing ring is
not correctly inserted.
