The bad US endoscope cleaning brushes are not long enough, and the bottom of the endoscope is not clean enough, which affected the accuracy of the experiment.

Learned that the overall length of the endoscope that needs to clean is 600mm. The other suppliers gave a matching brush diameter of 550mm, it is certainly not long enough. AOQUN makes the 650mm long US endoscope cleaning brushes. It was long enough to clean every corner of the endoscope.

In order to save money, some customer purchases a short US endoscope cleaning brushes. It turns out that not only can't save money, but also can't clean in place. Still need a long US endoscope cleaning brushes, please order from AOQUN.
