In high-speed centrifuges, the lid lock is more than just a closing mechanism—it is a critical safety feature. While many conventional centrifuges use a single locking system, Welso adopts a Patented Dual-Lock Design that combines mechanical self-locking and motor self-locking technologies for enhanced protection and reliability.

Limitations of Conventional Single Locks

Most centrifuges on the market use either a mechanical lock or an electric lock:

Mechanical Lock: Provides reliable locking during operation but may become less smooth over time due to wear.

Electric Lock: Convenient for automatic control, but the lid may be difficult or impossible to open during a power outage.

For high-speed applications, relying on a single locking mechanism can limit overall safety and operational flexibility.

Advantages of Welso's Dual-Lock Design

Welso's dual-lock system combines the self-locking capability of a worm-gear motor with an additional independent mechanical locking structure, creating two layers of lid protection.

Enhanced Safety

Two independent locking mechanisms work together to secure the lid. Even if one system experiences an issue, the second lock continues to provide protection, ensuring safer operation at high rotational speeds.

Smooth and Quiet Operation

The precision dual-lock design enables gentle lid engagement and release, reducing impact, vibration, and operating noise while improving user experience.

Manual Opening During Power Failure

Unlike some electric-lock-only systems, the dual-lock structure allows manual lid opening during a power outage, making sample retrieval and emergency handling much easier.

Longer Service Life

The optimized locking process minimizes mechanical stress and wear on components, resulting in improved durability and a longer operational lifespan.

Conclusion

For laboratories that demand the highest level of safety, a lid lock should provide more than basic protection. By combining mechanical self-locking and motor self-locking technologies, Welso's patented dual-lock system delivers superior safety, quieter operation, greater reliability, and longer service life—making it an ideal solution for high-performance centrifuges.
