7.4 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 gasket, 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 rubber mats and adapters to prevent any further damage.
4. Regularly check the rotor bores for deposits and damage.
7.5 Fuses
The fuse holder is located under the mains power socket.
1.
Pull out the power plug.
2. Remove the fuse holder towards the rear.
The two fuses can now be reached. The fuses can be replaced.
Instead of removable fuses, the Centrifuge 5430 R features a thermal overcurrent protective switch. The
mains power switch jumps to the '0' switch setting if the overcurrent protective switch is triggered.
1. Use the mains power switch to switch the device back on after more than 20 s.
2. If the mains power switch returns to the '0' switch setting, contact Technical Support.
7.6 Decontamination before shipment
If you are shipping the device to the authorized Technical Service for repairs or to your authorized dealer
for disposal please note the following:
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).
WARNING! Risk to health from contaminated device
1.
Follow the instructions in the decontamination certificate. It is available as a PDF file on
our webpage (www.eppendorf.com/decontamination).
2. Decontaminate all the parts you would like to dispatch.
3. Include the fully completed decontamination certificate in the package.
