FAQ
1. What is the testing principle of the Bubble Leak Tester and what parameters can it measure?
The Bubble Leak Tester is based on a positive pressure testing principle. During testing, a defined pressure is applied to the interior of a sealed package, container, or component. The tester determines whether a gross leak exists by observing whether bubbles are generated on the outside surface when the sample is immersed in liquid. Using this principle, the instrument can quantitatively evaluate sealing strength, heat seal quality, burst pressure, and overall leakage performance. It is also capable of analyzing bottle sealing properties, compressive strength, and burst resistance, providing reliable data for package integrity assessment.
2. What types of packaging and products can be tested with the Bubble Leak Tester?
The Bubble Leak Tester is suitable for a wide range of sealed products and packaging forms. These include medical device packages such as trays and combined packages, plastic tamper-evident bottle caps, inflatable packaging, ointment tubes, and various types of medical packaging. It can also be used for soft tube packaging used in toiletries, pharmaceutical ointments, and food products, as well as for aerosol valve sealing tests and pressure-resistance testing of blister packages.
3. How is the Bubble Leak Tester used in medical device packaging inspection?
In medical device packaging inspection, the Bubble Leak Tester is used to verify the sealing performance of sterile medical packages to prevent contamination during transportation and storage. It can detect gross leaks by internal pressurization and observe bubble formation, while also measuring critical indicators such as package pressure resistance, heat-sealing quality, and bursting pressure of the entire package. The tester supports the full test process required by YY/T 0681.5-2010, making it suitable for evaluating whether medical packaging meets integrity and safety requirements under controlled pressure and time conditions.
4. What control and display features does the Bubble Leak Tester offer?
The Bubble Leak Tester is equipped with an embedded high-speed microcomputer chip and a PLC industrial control program, enabling precise control of test pressure and time.
