DHS640 is a vacuum attenuation packaging container sealing integrity tester with dual sensor and dual cycle detection technology, which complies with USP standards1207. Technical Requirements for Evaluation of Quality and Efficacy Consistency of Generic Chemical Drug Injections, and Research Techniques for Sealing of Packaging Systems for Chemical Drug Injections

Technical Guidelines.

     The tester host is connected to a specially designed test chamber to accommodate the test packaging that needs to be tested. The packaging is placed in the experimental chamber to be vacuumed and subjected to

Vacuumize the cavity and reflect the leakage of the container by detecting the differential pressure pa during the pressure holding stage of the container. Determine whether the product is qualified or unqualified based on the threshold developed by the method Ge. At least 1 can be detected μ M's packaging is leaking. At the same time, the detection mode based on dual loops can achieve the ability of detecting micro leaks while covering the detection of large leaks  Ability.
