Maintains samples between -4°C and 40°C, crucial for preserving heat-sensitive biological materials like enzymes or RNA. Timer Settings: Digital control from 1 to 99 minutes. Operational Best Practices

| Frequency | Task (from updated manual) | Consumable/Part | | :--- | :--- | :--- | | | Clean rotor chamber with ethanol (70%); wipe lid seal. | Lint-free wipe | | Monthly | Inspect rotor lid O-rings for cracking; lubricate with Eppendorf grease (No. 5810 310.008). | Silicone grease | | Quarterly | Measure rotor runout (max 0.1 mm). Check motor carbon brush length (<5 mm = replace). | Carbon brushes (2x) | | Annually | RPM calibration using a tachometer (Offset ±2% max). | Calibration sticker | | Every 5 years | Replace lid lock solenoid and all rubber feet. | Service kit SK-5402 | If it persists empty, the motor mounts need replacement

For laboratories still operating the 5402, strict adherence to the and brush inspection (if applicable) is the primary determinant of longevity. The centrifuge remains a robust "workhorse" capable of precise pelleting, provided the user respects the kinetic limits and balancing protocols outlined in the technical documentation.

Fully adjustable from 1 to 99 minutes, or set to continuous operation ("Hold" mode). Design Features
