One customer needed to find syringe brush. The syringe brush that purchased by other manufacturers had scratched the syringe, in order not to affect the experimental results, all the scratched syringes have to be replaced, resulting in a huge loss. So, this customer asked AOQUN if they can make a syringe brush.

It was learned that the syringe was scratched because the previous syringe brush had bad head process, which made it very easy to scratch the syringe during cleaning. AOQUN recommend Customer to use the softer fan-shape head syringe brush, to ensure a good cleaning performance and no scratches.

After repeatedly tested and the customer found no scratching of Aoqun syringe brush.
