Briefly describe the test method and application skills of medicinal glass bottle round jump

        What do you think of when it comes to common medicinal glass bottles? Infusion bottles, vials, ampoules, oral liquid bottles... Because the memory drugs are directly related to human life and health, the quality of the bottles themselves is much higher than the standards of bottles used in other industries . The numerical test of round jitter is a must. One of the indicators.

Then, when examining the circular beating index of a medicinal glass bottle, such as an ampoule , what should be done to ensure that the accuracy of the test results is high, so as to achieve an ideal test? Below, Sai Cheng Xiaobian briefly describes the testing process and some test attempts.

Round beat test method

The bottom of the bottle is clamped and fixed on the rotating plate of the horizontal plate, so that the mouth of the bottle is in contact with the dial gauge, and 360° is read to read the large value of zui and the small value of zui, and the difference between the two is the vertical axis deviation value. , that is, the value of the round jump. (In essence, although the two are different, there is no difference in essence)

High precision skills

First of all, we must choose a high-performance test instrument , the core components of which are imported from well-known foreign brands. The " RBT- A Vertical Axis Deviation Tester " developed by Jinan Saicheng uses the imported core components to make good use of the three-prong self-centering chuck with high concentricity, and with a set of freely adjustable height and orientation. The high-degree-of-freedom bracket can meet the verticality deviation detection of important parts such as bottle body and bottle shoulder, and the result is high centering accuracy and high measurement accuracy.

Secondly, when the bottle vertical axis deviation reading pharmaceutically acceptable test values and calculating the difference between a large value and the small dial zui zui value, to ensure that the probe is a constant instrument dial opening is cleared and the center of the glass The connection is just past the vertical axis of the bottom of the bottle. Because we can't determine the position of the probe when the dial gauge is cleared, it must be accurate.

Further, the instrument itself to errors accumulate error test, the actual value of the axial misalignment test result is equal to the instrument itself vial sum of errors, so the test of medicinal bottles vertical axis deviation must be intelligent test selection, There is no need for manual operation of the instrument, and the instrument is designed according to relevant standards, otherwise the test results have no meaning. Responsible, the " RBT- A vertical axis deviation tester " developed by Jinan Saicheng is based on "QB2357-1998 polyester (PET) non-steam bottle" and "QB/T1868-2004 polyethylene terephthalate B". The glycol ester (PET) carbonated beverage bottle, the national pharmaceutical packaging container YBB00192003 "vertical axis deviation measurement method" and other standards designed and manufactured.

At present, Jinan Saicheng developed this " RBT- A vertical axis deviation tester ", with excellent performance, high cost performance has become the ideal of many bottle container manufacturers in many research institutes, food, medicine and other industries at home and abroad. A trusted professional detector.
