Some time ago, Penny from the Netherlands found us through Google. She said she wanted to buy the right brushes for the plastic test tubes in their laboratory. She said she was not sure about the test tube brush science definition and what test tubes should be equipped with which brushes.

Our gold customer Roger immediately responded to Penny, the test tube brush science definition, which uses a test tube brush with a general cylindrical head and a fan shape to effectively clean the test tube. Or the test tube brush to clean small pipes in addition to the conical part. What more, the cylindrical measuring test tube brush is with a common cylindrical fan head to achieve better cleaning results.

Aoqun is a professional manufacturer specializing in the production of high-quality mass-produced brushes. It has an R & D team with 11 years of industry experience. According to the size of the plastic test tube provided by Penny, Aoqun can customize a suitable size for her. Roger recommends that the plastic test tube brush uses 0.1mm pure nylon, which is soft and dense, and can play a good cleaning effect without scratching the inner wall of the test tube. After listening, Penny was very happy and asked us to proof her.

We sent a sample of the plastic test tube brush to Penny 2 days later. After receiving the sample test, she said: "I used a brush to clean the plastic test tube many times. The cleaning effect is very good and the test tube has not been scratched, and I am very satisfied with the definition and the combination of test tube brushes. "Penny then decided to first place a sample list of 2000 test tube brushes, and there will be a re-order later.
