Original standard: Ampoule bottle circular jumping test method

Ampoule bottle is a small glass container used to hold medicinal liquids, commonly used for storing injectable drugs, vaccines, serum, etc. It has the characteristics of small expansion coefficient, good heat resistance, low melting point, and easy to melt and seal.

As a commonly used pharmaceutical packaging material, the quality performance of ampoules is a key concern for ampoule manufacturers, ampoule users, and other enterprises. It mainly includes the breaking force, circular jumping, wall thickness, stress, etc. of ampoules. This article will focus on the testing method of ampoule circular jumping (also known as vertical axis deviation).

according to the standard
GB/T2637-2016 Ampoules, YBB0033202-2015 Low borosilicate glass ampoules, YBB003205-2-2015 Medium borosilicate glass ampoules, YBB00192003-2015 Determination of vertical axis deviation

Test Principle
Fix the bottom of the bottle onto the rotating disc of the horizontal plate, so that the bottle mouth contacts the dial indicator. Rotate 360 ° to read the large and small values, and half of the difference between the two is the circular runout (vertical axis deviation) value.

Testing equipment

The instrument used to test the circular runout of ampoules is called a circular runout tester, also known as a circular runout tester, vertical axis deviation tester, verticality deviation measuring instrument, etc. This article will combine the production of Jinan Zhongce Electromechanical Equipment Co., LtdCircular jump testerVDT-01， Introduce the operation method for ampoule round bounce test.

Circular jump tester

Operation Method
Clamp and fix the ampoule to be tested on the fixture of the circular jumping tester, so that the dial gauge is in contact with the bottle mouth, and set the dial gauge to zero. Rotate the instrument chuck 360 ° and read the large and small values. Half of the difference between the large and small values is the circular runout (vertical axis deviation) value of the test ampoule.
