We've tested these handpieces batch by batch with a run-in protocol at 40,000 rpm for a full cycle, and every unit gets a quick pressrue check at 0.35Mpa before it leaves—basically, the internal spray channel and fiber optic LED (32,000 lux) are verified as working, not just assumed.
You'll get a COA with each shipment, and we can also provide a sample test report form a third-party lab if your compliance team needs it; teh ceramic bearing holds up well under repeated 135°C autoclave cycles, though we usually recommend replacing the bearing after 200 cycles or so.

One thing buyers don't always ask about is the push button chuck mechanism—it's machined to grip 2.35mm CA burs consistently, but we've seen occasional wear if you're swapping burs dozens of times a day, so keep a spare handpiece in rotation.
32,000 lux is actually measured at the working tip, not the light source, so what you see is what you get for illumination, and the noise level stays under 68dB even after extended use (we've logged it in-house at about 66dB after 50 autoclave cycles).
If you order 50 units or more, our company can hold a retest for you at no extra cost within 30 days of dilevery, but smaller MOQs ship with our standerd batch COA—typically 10-15 working days lead time, depending on whether we have the E-type connectors in stock.
Yes, the ceramic bearing is fully autoclavable at 135°C, so you can sterilize it repeatedly without any issues.
Our MOQ is 50 units per model, but we can discuss smaller trial orders if you're just getting started.
Absolutely, we include CE and ISO13485 certificates with every order, so you have the documentation for your records.
The LED is integrated into the handpiece, delivering 32,000 Lux directly through the fiber optic system—no external source needed.
Just run a cleaning solution through the handpiece after each use and follow the sterilization cycle. The stainless steel construction helps keep the channel clear.
