As a commonly used pharmaceutical packaging container, the sealing performance of the vial is directly related to the quality and safety of the drug. In order to effectively evaluate the sealing performance of vials, the non-destructive leak tester came into being. This article will focus on how the vial non-destructive leak tester works, where it can be used, and what benefits it offers.
First, the working principle
During the test, the instrument is set up with two main chambers: the standard chamber and the test chamber. The standard chamber is used to provide a constant pressure environment, while the test chamber is used to place the vial to be tested. Before the start of the test, the pressure of the two chambers was equal. When the specimen is placed in the test chamber, if there is a gas leak in the vial, the pressure in the test chamber will change. This pressure change is precisely captured and converted into an electrical signal by a differential pressure sensor, which is then calculated by an internal algorithm to calculate the leakage pore size and leakage flow.
2. Application scenarios
Vial non-destructive tightness tester is widely used in pharmaceutical, biological products, food and other industries. In these areas, the tightness of the vial is directly related to the shelf life, stability and safety of the product. By using a non-destructive leak tester, companies can quickly and accurately assess the sealing performance of vials without damaging product packaging, ensuring product quality and consumer safety.
3. Advantages and characteristics
Non-destructive testing: The vial non-destructive tightness tester can be tested without damaging the product packaging, avoiding the waste of resources and environmental pollution caused by testing.
Accuracy measurement: Through differential pressure sensors and internal algorithms, the tester is able to accurately capture pressure changes and calculate leakage pore size and leakage flow, providing strong support for product quality control.
Fast and efficientCompared with traditional destructive testing methods, the non-destructive leak tester has higher detection efficiency and can complete the detection of a large number of samples in a short time.
Easy to operate: The tester adopts a user-friendly design, which is simple and convenient to operate, even for non-professionals.
High reliabilityAfter strict quality control and production process, the vial non-destructive tightness tester has a high degree of stability and reliability, which can ensure the accuracy of the test results.
To sum up, the vial non-destructive tightness tester plays an important role in the pharmaceutical, biological, food and other industries with its unique working principle, wide range of application scenarios and significant advantages.
