Eppendorf Centrifuge 5424 R Service Manual !new! Jun 2026
Understanding the physical limits and engineering thresholds of the Centrifuge 5424 R is critical before attempting any service or calibration work. Performance Benchmarks 15,000 RPM (Rotations Per Minute). Maximum RCF: 21,130 × g (Relative Centrifugal Force). Temperature Range: -10°C to +40°C.
Place a wireless temperature probe inside a water-filled tube in the rotor. Run the unit at 4°C for 20 minutes to verify equilibrium.
Disclaimer: Attempting repairs without proper training can void the warranty and cause damage to the device.
Inspect the rotor, rotor lid, and adapters for signs of corrosion or micro-fissures.
Maintaining this equipment requires a clear understanding of its technical architecture. This guide synthesizes the essential maintenance protocols, error codes, and technical workflows typically found in the official Eppendorf service documentation. Technical Specifications and Architecture
| Error Code | Symptom / Message | Typical Cause | Recommended Remedy | | :--- | :--- | :--- | :--- | | | Lid cannot be locked. | User error. | Try to close the centrifuge lid again. | | LID ERROR | Lid cannot be released. | Software glitch. | Switch device off and on again, then press the open key. If error persists, use the emergency lid release. | | LID LIFT (5424 R) | Lid not opened wide enough. | Mechanical obstruction. | Open the centrifuge lid wider by hand. | | NO RPM | Error in speed measuring system. | Electronic glitch. | Leave the device switched on for 10 seconds or up to 6 minutes until the error clears. | | Err 6 | Drive error / Drive overheated. | Overload or thermal event. | Repeat the run. If error reoccurs, power cycle after >20s. For overheating, allow drive to cool for ≥15min. | | Err 7 | Deviation in speed control. | Rotor not tightened. | Wait for rotor stop, then tighten the rotor firmly. | | Err 9–17 | Electronic system error. | Electronics. | Switch the centrifuge off and back on after >20 seconds. | | Err 18 (5424 R) | High temperature variation. | Airflow blocked / ice buildup. | Check vents and settings. Thaw ice or switch off to cool down. | | Err 19, 24 (5424 R) | Cooling circuit overheated / fault. | Poor ventilation / overheating. | Check air circulation, clear vents, and allow unit to cool down. | | Err 20, 21 (5424 R) | Temperature sensor faulty. | Hardware failure. | Power cycle the centrifuge after >20 seconds. If error persists, contact service. | | Shaking on Startup | Imbalance. | Rotor loaded asymmetrically. | Stop, reload symmetrically, and restart the device. | Temperature Range: -10°C to +40°C
Includes the motor and rotational speed sensors (tachometer).
Wait at least 3 minutes after unplugging the unit to allow internal power supply capacitors to fully discharge. 3. Preventative Maintenance Schedule
Ensure the rubber feet are intact and the unit sits perfectly level on the benchtop to prevent vibration issues. Cleaning and Lubrication wipe dry if present.
Check the chamber interior for any condensation or ice buildup; wipe dry if present. Inspect the rotor bowl seal for cracks or degradation. Monthly Tasks
Eppendorf Centrifuge 5424 R is a refrigerated microcentrifuge designed for high-performance lab tasks. Its service and maintenance protocols ensure operational safety and prolong the lifespan of the equipment. Key Technical Specifications The device features two interface variants: rotary knobs

Pathways are directional marks and shapes for our eyes to follow across a 2 dimensional artwork. They are a powerful compositional tool to keep the viewer’s eyes engaged and moving around a composition. They’re also great for artists to practice, because they emphasize that if we’re to think compositionally, each part must play a role …
