Mr. Hulk from the United Kingdom sent us an enquiry, saying that they wanted to find narrow instrument cleaning brushes for the tubes in their laboratory. Because their tubes are small and it’s not the common tube size, he hopes that we can customize narrow instrument cleaning brushes for him and send him samples.

After receiving Hulk's information, we learned about the size of the tube, the tube diameter is only 6mm and it has a total length of only 30mm. It looks like a normal tube, but it is extremely small. We customized narrow instrument cleaning brushes based on the size of Hulk’s tube. The narrow instrument cleaning brushes has a diameter of only 6 mm and a total length of only 50 mm, with soft, short nylon bristle, which can clean the small tube very well.

After we sent sample to Hulk, he cleaned the small tube immediately. Although narrow instrument cleaning brushes is small, but it has an excellent cleaning performance on the tube, and Hulk is very satisfied with it. He no longer worries about the problem of cleaning the small tubes. Hulk decided to purchase 1000 narrow instrument cleaning brushes from us.
