Measurement Method and Principle of Ampoule Circular Bounce Testing Machine
Date: 2023-11-14Read: 6
Ampoules are one of the widely used direct contact drug packaging containers in liquid medicine packaging. According to the different materials used to make ampoules, they are divided into low borosilicate glass ampoules, neutral borosilicate glass ampoules, and high borosilicate glass ampoules. Low borosilicate glass ampoules are commonly used in production enterprises nowadays. In terms of cost-effectiveness, some ordinary drugs can be satisfied with low borosilicate ampoules, but for some acidic and alkaline varieties, low borosilicate glass ampoules cannot meet the requirements. The strong acid and alkali resistance of neutral borosilicate glass ampoules enhances their performance. Regardless of the material of the ampoule, its circular runout must be measured, which refers to the maximum change in the outer diameter of the wire when it rotates around the axis once.
Excessive circular deviation not only affects the aesthetic appearance of the ampoule itself, but also causes leakage of liquid drugs, resulting in contamination of the production table and waste of drugs. It may even cause the ampoule to tilt and affect the operation of the entire production line.
Therefore, production enterprises must strictly control the safety issues of ampoule quality, so that the quality indicators of ampoules meet national requirements. According to the standard, the YTD-80 ampoule circular jumping tester with an accuracy of 0.01mm can be used for measurement.
Testing principle: Fix the bottom of the bottle onto a rotating disc on a horizontal plate, so that the bottle mouth is in contact with the dial indicator. Rotate 360 ° to read the maximum and minimum values, and calculate the maximum change as the circular runout value. The instrument cleverly utilizes the high concentricity of the three jaw self centering chuck, combined with a set of high degree of freedom brackets that can freely adjust height and orientation. It can not only measure the circular jumping value of ampoules, but also meet the vertical axis deviation measurement of some penicillin bottles, small infusion bottles, and various small control bottles.
