LEAK-M
Micro Leak Tester
LEAK-M Micro Leak Tester is designed based on the vacuum decay method and conforms to the requirements of ASTM F2338-09. It is applicable to test the sealing integrity for different volume injection and lyophilized pharmaceuticals such as vials, ampoule bottles, infusion bottles, prefilled syringes, eye drops bottles, liquid filled packaging, non-porous flexible packages, rigid and semi-rigid packaging. It is also suitable for the detection of minimum leakage points and pinholes in blister packaging, semi-rigid or rigid packaging such as glass vials.

Security protection
The test chamber adopts liquid anti-leakage design to effectively ensure the safety of the sensor.
Intelligent configurations such as overload protection and power-off memory effectively ensure the user's operation safety.
Over-range shutdown function to effectively protect the sensor.

Test Principle
The host is connected to a vacuum decay chamber, the sample is put into it and vacuumed, there is a pressure difference between the inside and outside of the sample, and the gas enters the vacuum decay chamber and the host through the leak hole. The host uses a pressure sensor and a differential pressure sensor to monitor the vacuum degree change in the test chamber, judging whether the sample is qualified by the change of vacuum degree.

Method |
Put the sample into water and vacuumizing, observing the leakage situation by whether there are steady progression of bubbles from the specimen or whether the Methylene blue water enters the sample after vacuum reduction |
Punch a hole on the object to be measured, flush gas into it, and put it into water. Observe whether there is a dew point by observing whether there are bubbles emerging during the pressure maintaining process. |
Put the sample into the vacuum chamber, and observe the coincidence of the pressure curves of the sample and the standard sample after vacuumizing, so as to judge whether there is leakage or not |

Summary |
The vacuum method is a commonly used method to test the leakage. According to research, although water molecules can pass through when encountering a 5um leak, but it is different to observe when encountering a 5um micropore infiltration of liquid during testing, which makes misjudgment. And the sample can’t be used again after leak testing. |
Each sample for destructive test can only be used for preliminary research, not suitable for product delivery inspection. |
Although the vacuum decay leak tester is expensive, it is currently a more effective, intuitive and efficient leak detection method. Besides, the sample will not be contaminated after inspection and can be used normally. |
