Periodic Maintenance
- Lubricate moving parts (such as rotor seals, if applicable) according to the manufacturer’s recommendations to reduce wear and ensure smooth operation.
- Calibrate speed and timer settings regularly to maintain precise and consistent centrifugation.
- Schedule professional servicing in line with the manufacturer’s maintenance schedule. This helps detect hidden issues, ensures compliance with warranties, and extends equipment life.
- Store with the lid slightly open when not in use to prevent condensation and odors, and to improve internal ventilation.
Best Practices for Safe Operation
- Train all users on correct operation and maintenance procedures. Well-trained staff reduce the risk of misuse and equipment damage.
- Keep a maintenance log documenting cleaning, inspections, servicing, and repairs.
- Always refer to the manufacturer’s instructions for model-specific maintenance and troubleshooting.
Quick Reference Table: Maintenance Checklist
| Task | Frequency | Purpose/Benefit |
|---|---|---|
| Clean rotor & chamber | After each use | Prevents corrosion and contamination |
| Inspect rotor & buckets | Before use | Ensures safety and extends component lifespan |
