The Eppendorf 5402, when paired with an updated manual and a strict preventative maintenance schedule, remains a capable backup or low-throughput centrifuge. However, if your lab cannot locate a verified Rev. 5 or later manual, or if the lid lock has never been retrofitted, it is time to retire the unit. Modern equivalents like the Eppendorf 5425 or 5430 R offer better energy efficiency, quieter operation, and full digital documentation.

Operating at sub-ambient temperatures causes ice buildup on the chamber walls. Switch off the centrifuge and unplug the power cord. Leave the lid open to let the ice melt naturally. Soak up the melted water with a cloth. Wipe the chamber dry before restarting the unit. 5. Updated Troubleshooting and Error Codes
If a tube breaks containing infectious agents, the operator must wait 30 minutes for aerosols to settle before opening the lid. Wear appropriate PPE. Decontaminate with a 1:10 diluted bleach solution or 70% isopropanol, ensuring the contact time does not corrode the aluminum rotor.
