In March, I received an enquiry from Jim in the United States, feedback that the lab tube brush purchased from another supplier scraped their customer's test tube, causing a large number of customer complaints, and at the same time, the order was also constantly decreasing.

Our gold sales customer service Mary responded promptly 1 minute after receiving Jim's email and learned the specifications of the lab tube brush to be purchased. At the same time, I saw through the picture that the head of the lab tube brush purchased before was very sharp, and it was easy to scratch the test tube. Mary told Jim that the brush head used for test tubes is usually cut off, but the head needs to be reprocessed again to make the head smoother, so that not only can it be cleaned when cleaning, but also solve the scratch the problem. Jim was very satisfied with our professional response.

Two days later, Jim received the lab tube brush sample and arranged the test for the first time. It was found that the sample provided by Aoqun will not scratch the test tube, and it was cleaned very cleanly.
