Kay from Saudi Arabia contacted us that they are professional buyers who want to buy a batch of different sizes of instrument brushes and sterile processing for their customers. Kay wants us to recommend her regular test tube size so that they can make choices and adjustments.

We told Kay that our brush sizes are tailored to the customer's needs, and we can customize the instrument brushes and sterile processing for each tube based on the usual tube size on the market. We often make the size of the brush, diameter 15-20mm, total length 180-230mm. If there is any need, such as wishing for a larger diameter, a smaller diameter, or a longer length and a shorter length, we can customize them. We sent our brush with a diameter of 18mm and a total length of 200mm; a diameter of 20mm and a total length of 230mm as a sample to Kay.

After receiving the samples of instrument brushes and sterile processing, Kay sent the samples to their customers. After testing, their customers informed the required size of the test tube as follows: diameter 17mm, total length 210mm; diameter 21mm, total length 230mm. After several days of communication, we finally reached a cooperation.
