First of all, surely the medical capillary tube is much higher than the requirements of the tube for the food industry. Then it is necessary to select the material can not be alone only from the price to consider. As the saying goes, you get what you pay for. There are three directions of dirt on the inner wall of the tube, 1 is the use of the tube in the process of cleaning is not thorough. 2 tube itself anti-corrosion and anti-fouling poor, in the use of chemical reaction corrosion, (more difficult to clean). 3 tube itself within the wall of the environment is not good, can not do a thorough cleaning. In addition to the above three cases need to be replaced in 2 cases of better tubing outside of no other hair. Another 1, 3 two cases need to confirm whether the pipe wall finish to meet the requirements (general medical are more than 0.1um), only the pipe wall to achieve this condition is in line with the requirements of the medical pipe, and the domestic absolute pipe is not up to standard. There is no way to do a thorough cleaning.
The main topic. Capillary cleaning is generally. Acidic liquid or alkaline liquid rinse (conditions allow the addition of ultrasonic)
Pure water rinse, wind blowing, pure water rinse, blow drying, pure water rinse
Specializing in capillary tube inner wall polishing. Domestic only through the physical polishing of micro-sampling syringe, suction needle, filling needle, dispensing needle, adding sample needle, such as capillary holes, stainless steel capillary tube, inner diameter of 0.3mm-10mm inner wall polishing. Ra0.1um above the inner surface, widely used in high-end medical equipment, food and drug, analytical instruments and semiconductor equipment.
