Suitable for medicinal glass bottles, vials, plastic solid bottles, blister packaging, aluminum-plastic soft bags, syringes, pipettes, vacuum packaging bags, cans, milk powder bags, aluminum foil bags, eye drop bottles, medical device packaging, Negative pressure seal leakage test and microbial intrusion test for packaging materials such as liquid bags, jelly cups, caps, cosmetic bottles and bags, daily chemicals, etc. are widely used in pharmaceutical manufacturers, pharmaceutical packaging material manufacturers, drug testing centers, medical device companies, food companies, Seal integrity testing for cosmetics companies and other industries.
Test principle:
By evacuating the vacuum chamber, the sample immersed in water will generate an internal and external pressure difference, and observing the escape of gas within the sample, in order to determine the sealing performance of the sample; by evacuating the vacuum chamber, the sample will generate internal and external pressure. Observe the sample expansion and shape recovery after releasing the vacuum to determine the sealing performance of the sample. Comply with GB/T 15171 "Test Method for Sealing Performance of Flexible Packages", ISO and other standards.
