: Common error codes for this era of Eppendorf centrifuges (like Error 6 or Error 8) typically relate to motor/brake malfunctions or loose rotors. Centrifuge 5420 - Eppendorf
The Eppendorf 5402
is a legacy refrigerated microcentrifuge known for its robust performance in handling temperature-sensitive samples in molecular biology and clinical research. While newer models like the Centrifuge 5420 have succeeded it, the eppendorf 5402 manual updated
remains a common fixture in labs as a reliable refurbished unit for DNA precipitation and cell lysate separation. Key Performance Specifications Variable Speed Range: Achieves speeds up to 14,000 rpm.
Temperature Control: Adjustable from -4°C to 40°C (some documentation indicates a range down to -9°C).
Fast Cool Function: Capable of cooling the rotor chamber from ambient temperature down to 4°C in approximately 10 minutes.
Rotor Capacity: Typically accommodates an 18-place rotor for 1.5 mL and 2.0 mL tubes.
Digital Interface: Features digital controls for precise adjustment of time (1 to 99 minutes), temperature, and speed. User Experience and Operational Insights Reliability: The
is often described as an "old school" workhorse. Its brushless, maintenance-free motor design contributes to its longevity in high-throughput environments.
Noise and Ergonomics: Like most Eppendorf models, it is designed for low noise levels to minimize lab disruptions.
Critical Maintenance: For units still in operation, regular cleaning of the rotor and seals with distilled water and mild detergents is essential to prevent corrosion. Users should ensure symmetric loading for balance to avoid drive errors. Common Issues and Troubleshooting Refrigeration Failure: A common failure point in older
units is the cooling function, which may fail while the centrifuge still operates at room temperature.
Rotor Recognition: If the unit displays errors like Error 3 or Error 23, it typically indicates the system is not detecting the rotor or there is a drive recognition fault; restarting the device often resolves minor glitches.
For those looking for current documentation, technical guides and software updates are available through the Eppendorf Download Center. ? Centrifuge 5420 - Centrifuge for Eppendorf tubes The Eppendorf 5402 is a legacy refrigerated microcentrifuge
Document Purpose: To serve as a practical supplement to the original Eppendorf 5402 instruction manual (cat. no. 5402 000.010). This guide incorporates current safety standards, rotor care protocols, and troubleshooting insights not detailed in the original 1990s publication.
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.
Bottom line: The machine is only as reliable as the manual that guides it. Track down the updated Eppendorf 5402 manual, verify its revision, and follow every safety addendum. Your samples—and your lab safety record—depend on it.

Eppendorf 5402 is a refrigerated microcentrifuge designed for high-performance laboratory tasks, offering precise temperature control and high-speed capabilities. While originally released as a legacy model, it remains a staple in many labs for its durability and digital control system. Key Technical Specifications
The 5402 is optimized for temperature-sensitive samples, with a cooling range of -4°C to 40°C GMI - Trusted Laboratory Solutions Maximum Speed: 14,000 RPM (approximately 16,000 x g). Speed Adjustment: Adjustable in 100 RPM increments. Timer Range: 0 to 99 minutes, with a dedicated Short Spin button for rapid pulses. Typically accommodates up to 18 x 1.5/2.0 mL tubes Control Panel:
Features digital displays for simultaneous monitoring of time, temperature, and speed. Standard Operating Procedures Rotor Installation:
Ensure the rotor and rotor nut are firmly tightened using the provided rotor key. Always load tubes symmetrically by weight and volume to prevent imbalance. Lid Operation:
The lid must be firmly closed to engage the safety lock; the device will not run until locked. Running a Cycle:
Set your parameters, then press the "Start" button. For quick spins, hold the "Short Spin" button; the rotor will spin as long as it is depressed. National Institute of Standards and Technology (.gov) Maintenance & Safety Guidelines
