Laboratory equipment plays a critical role in producing accurate and reproducible experimental results.
Instruments such as micropipettes, centrifuges, vortex mixers, PCR systems, and incubators require regular maintenance to maintain performance and reliability.
Without proper maintenance, laboratory equipment may experience:
- Reduced accuracy
- Unexpected failures
- Sample contamination
- Increased repair costs
- Shortened service life
A preventive maintenance routine helps laboratories avoid these problems and maintain efficient workflows.
