Eppendorf 5804R Refrigerated Centrifuge
The Eppendorf 5804R Refrigerated Centrifuge provides powerful separation in PCR tube strips and 1.5/2 ml test tubes as well as high-volume centrifugation oftubes, flasks and filter plate systems and practically all applications. The 5804R offers a speed range up to 14,000 RPM and temperatures from -9°C to 40°C. This refrigerated unit features continuous cooling after the run has completed to protect your samples. ECO shut-off for reduced energy consumption and to extend compressor life. Dynamic compressor control technology for optimized cooling performance. We may have different adapters available depending on the rotor chosen with this centrifuge. If the selected rotor includes adapters that will not work for your application, please inquire.This centrifuge is in excellent condition and will be fully tested to perform at factory specifications before being shipped.
Please confirm the selected rotor meets your application needs and request a different rotor, if necessary. Available rotors can be found in our Rotor Compatibility Guide.
The Eppendorf 5804R Refrigerated Centrifuge includes:
- > Rotor Selected Above
- > NIST Centrifuge Calibration and Preventative Maintenance Report
- > Operator's Guide
- > Power Cord
- > Full 180 Day Parts and Labor Warranty

- Confirm the power supply output voltages match specified requirements for stable distribution to all internal components
- Measure and verify voltages at PCB test points to ensure accurate power delivery and circuit integrity
- Confirm rotor compatibility with the centrifuge model and check that rotor detection systems recognize the rotor type
- Inspect the exterior for any cosmetic or structural damage that could affect performance or safety
- Check the door mechanism alignment to ensure secure and smooth opening and closing
- Inspect and replace the gas strut with an OEM part to maintain proper door support and safety
- Examine the rotor chamber bowl for dents or damage and replace as needed to ensure safe operation
- Replace and confirm full functionality of all lid lock switches to maintain secure closure
- Inspect and lubricate the door lock mechanism, applying grease to the lid lock rail for smooth operation
- Test compressor functionality (if applicable) to ensure proper operation and consistent temperature control
- Conduct an 8-12 hour cycle test to validate consistent performance over prolonged use
- Confirm rotor motor stability, check for unusual noise, and assess mechanical integrity during operation
- Inspect the condensation drain and clear any clogs to prevent moisture buildup in the rotor chamber
- Verify RPM accuracy using an NIST-traceable tachometer and perform calibration as necessary
- Check the centrifuge error log to ensure zero recorded issues, confirming system reliability
