The standard 18-place Eppendorf rotor and its lid are fully autoclavable at 121°C for 20 minutes to eliminate biological contamination. Always remove the rotor from the unit before autoclaving. 5. Troubleshooting Common Error Codes
Maintains the set temperature even when the lid is closed and the rotor is stationary, protecting proteins and nucleic acids from degradation. 3. Step-by-Step Operating Instructions
Standard error codes and maintenance steps for Eppendorf microcentrifuges often apply across related models like the 5417 or 5424. Common issues include: Eppendorf 5402 Refrigerated Centrifuge - G-M-I, Inc.
For brief, rapid spins. The centrifuge runs at maximum speed as long as the key is held down. eppendorf 5402 manual updated
When the Eppendorf 5402 encounters an operational variance, it displays specific indicators or exhibits clear mechanical symptoms. Symptom / Error Potential Cause Action Required Imbalanced rotor loading. Stop the run immediately. Check tube symmetry and weight. Centrifuge Will Not Start Lid is not fully engaged or microswitch is faulty.
In the rapidly evolving world of molecular biology and clinical diagnostics, centrifuges are the silent workhorses of the laboratory. Among the legacy equipment that still commands respect in many labs is the . While newer models have since entered the market, the 5402 remains a reliable refrigerated microcentrifuge—provided you have the correct documentation. This article focuses on the importance of the updated Eppendorf 5402 manual, what changes to look for, and how to ensure safe, compliant operation.
Always load tubes across the center axis of the rotor. The standard 18-place Eppendorf rotor and its lid
| Symptom | Probable cause | Solution | |---------|---------------|----------| | Lid won’t open | Rotor still spinning or mechanical latch stuck | Wait 2 min. If still locked: unplug unit, wait 10 sec, replug → lid solenoid releases. | | Display shows “E” | Overload or electronic fault | Reduce load. If persists, internal fuse (F1, 1.6A slow-blow on PCB) may be blown. | | Excessive vibration | Unbalanced load or bent rotor | Rebalance. Remove rotor, roll on flat surface – wobble = replace rotor. | | No start, display “0” | Lid switch failure | Bypass not recommended. Replace lid microswitch (Eppendorf part 5402 800.011). | | Grinding noise | Motor bearing wear | Replace motor (service only). Average bearing life: ~5,000 hours at max speed. |
Digital adjustment from 1 to 99 minutes, plus a "momentary" button for short spins. Updated Maintenance & Safety Guidelines
Maintain a safety clearance zone of at least 30 cm (12 inches) around the entire perimeter of the centrifuge. Keep this zone clear of hazardous materials and external laboratory equipment. including technical specifications
Close the lid tightly until the lock clicks into place. Run Parameter Selection: Set the Speed (RPM/RCF) and Time.
