Applications & Industries
Leak test chambers: applications and sectors of use
Sector 01
Pharmaceutical industry
In the pharmaceutical industry, leak testing is a critical step in the packaging process. A poorly sealed blister pack compromises the integrity of the tablet and can lead to contamination ; a syrup bottle that is not properly closed may leak or oxidize.
Our testing chambers enable you to accurately detect leaks in all of your pharmaceutical packaging. The AGILEAK model meets the traceability requirements set forth in FDA CFR 21, thanks to its data export capabilities, profile manager, and built-in connectivity. Each test is time-stamped, exportable and integrable into your quality systems.
In the food industry, packaging seal integrity directly affects food safety: a defective modified-atmosphere tray can break the cold chain, cause oxidation or compromise the use-by date.
Our chambers allow you to define and control acceptable seal levels for each packaging reference, in immersion or dry testing. The ASTM D3078 compliant test mode ensures reproducible results and instantly flags any defects, allowing the operator to take action without interrupting production.
Sector 02
Food industry
Sector 03
Cosmetic industry
The cosmetics industry is one of the most demanding sectors when it comes to packaging leak-tightness. Perfume bottles, cream tubes, pump bottles : each container has its own sealing requirements, and even the slightest deviation in production can lead to leaks, customer returns, or non-conformities.
Our test chambers check the dry leak-tightness of all your containers, regardless of their shape or size. The CTS offers a quick and intuitive pneumatic test, while the CTE allows for precise control of vacuum pressure and timing to accommodate each packaging specification.
Sector 04
Bottling & Chemistry
In the bottling and chemical industries, leak-tightness is a fundamental safety requirement. Defective packaging can lead to leaks of hazardous materials, product damage, or production line incidents.
Our testing stations are used at several stages: quality control at the end of the production line, qualification of welding parameters, and preventive maintenance on sealing equipment. Robust and precise, they are compatible with a wide variety of containers and can maintain a vacuum of up to -950 mbar.
Frequently Asked Questions
FAQ — Everything You Need to Know About leak tester chamber
01
Why use a vacuum chamber to test for leaks ?
Vacuum chamber testing is the most reliable and visually effective method for detecting air or gas leaks. The principle is based on creating a pressure differential between the inside of the package and the chamber of the box. In immersion testing, the packaging is submerged in water—under vacuum conditions, the trapped air creates a stream of bubbles at the exact location of the defect. When dry, droplets can be seen forming on the outside of the container.
02
What are the reference standards for leak testing ?
The most common protocols include : ASTM D3078 (leakage in flexible packaging by bubble formation), ASTM D6653 (high-altitude testing—air transport simulation), ASTM D4991 (rigid containers for hazardous materials), and ISO 20484 (general principles of leak testing).
03
What are the common causes of leaks in production ?
Chamber analysis is an excellent diagnostic tool. The most common causes are : improper sealing parameters (temperature too low or uneven sealing pressure), contamination of the seals by powder or liquid residue, or material defects (micro-perforations caused by handling or sharp objects inside the package).
04
What is the difference between CTS, CTE, and AGILEAK ?
The CTS is a fully pneumatic vacuum bell jar that requires no operator maintenance, making it ideal for quick and easy testing. The CTE is a pneumatic dry chamber with vacuum control and a timer capable of up to 999 seconds. The AGILEAK is the next-generation touchscreen model : data export, profile manager, custom testing, and CFR 21 compliance for the pharmaceutical industry.
05
What is the average lifespan of a leak testing chamber ?
The average lifespan is 10 to 15 years with proper maintenance. It may vary depending on how often it is used. ACRN offers a standard 2 year warranty on all its enclosures, as well as dedicated after-sales service to ensure the longevity of your equipment.
06
Do you offer training on how to use the boxes ?
Yes, ACRN offers comprehensive training for your teams covering operation, basic maintenance, and safety procedures. These training sessions can be conducted on-site during installation or remotely, depending on your needs.
