Bench-top O2 analyser & leak detector

The AlphaLab is a bench-top leak tester dedicated to flexible packaging testing for the food, pet care and cosmetic Industries. It has been specially designed for laboratories in Factories that have to follow stringent Quality Inspection procedures and processes like ISO 22000 & HACCP.

It is made up of an AlphaLeakTester and an AlphaTower.

The AlphaLab is used for leak testing and altitude simulation.
The altitude simulation is designed to identify the altitude at which your packaging will start to leak when subjected to pressure differences such as during air transport.

To test your packaging, place a sample under the perforating tower of the AlphaLab, adjust the tower manually downwards until it is in contact with the sample, the test begins. You can test as many samples as you wish.

Full digital results are immediately available (the AlphaLab will measure leaks > 5 μm), visible on a screen, they can be transmitted to your computer via a USB connection.

Warranty: 3 years.

  1. Unique precision.

The AlphaLab has been developed for flexible packaging, and uses flow measurement at a constant pressure.

  1. Altitude simulation.

The altitude simulation has been developed to identify at what altitude a flexible packaging starts to leak when it is transported by air. This unique feature is exclusive to Astaara.

  1. Immediately available digital data:

Tests results (destructive test) can be instantly transmitted to your computer via a USB connection. Analyse the results on a pivot table in order to identify the area to improve, and visualise them on a Gauss chart.

  1. Accurate analysis results:

No more blocked needles compromising the results of your tests, no more guessing the size of the bubbles. Well adapted to packaging where there is little or no headspace (chocolate bar…), the AlphaLab will deliver extremely accurate results to help you to improve your process in a very short period of time.

  1. Cost savings:

With the AlphaLab, you can measure the sealing of films of different thicknesses, and select the best performing one, which is not necessarily the thickest and most expensive. With the Perforating Tower, consumables like septa and needles are no longer needed.

  1. ISO 22000 & HACCP compliance:

Identify flexible packaging related critical points, conduct root cause analysis, establish your critical limit, test, correct, verify & document easily with the AlphaLab. Avoid product recall by making sure your food is safe to consume until the last day of the shelf life.

  1. Modified Atmosphere Packaging (MAP) packaging Control:

The AlphaLab will check that your products are within the acceptable leak range & that they will be preserved until the last day of the shelf life.

  1. Brand protection and lasting taste for your products:

Avoid humidity and bacteria getting into your package and compromising the taste of your products. For potato chips manufacturers, preserve the crispiness and pillow effect.

  1. Visualize the size of the leak:

When you test samples, the AlphaLab may deliver very different leak values, like 1 cc/mn or 30 cc/mn or 100 cc/mn. Sometimes, it is necessary to be able to visualize if it is a very small leak, or an important one. The AlphaLab has a coupler connection on the front panel that enables to you connect an accessory (supplied as a standard) with a small adjustable flow controller. You have to connect this accessory to the front panel by pushing the probe into the coupler, and put the other end in a glass of water. By turning the knob on the small flow controller, you will be able to adjust the flow, and therefore, visualize the bubble size output of the same leak in the glass of water.


To check the calibration of your AlphaLab annually, Astaara offers an optional calibration check kit, the CharlieCal. It is an extremely simple operation, and you don’t need to have your equipment verified by professionals. This accessory allows you to compare the flow rate of your instrument against that of a calibrated leak. If the flow rate of the AlphaLab at a given pressure is between the minimum and maximum limits, no further checks are needed, and you can continue to use your AlphaLab. If not, further investigation is required.

The AlphaLab consists of 2 separate units: an AlphaTower (patented perforating device) and an AlphaLeakTester (leak testing unit). The AlphaTower and the AlphaLeakTester are communicating via a PS/2 cable and a PU tubing.

1/ Why do I need a special leak tester for flexible packaging? Are the leak testers
available not suitable?

Most leak tester would use a leak test method known as Pressure Decay, which measures the difference in pressure during the test. Problem is that, for flexible packaging, the Volume of the package is also changing during the test. And since Pressure x Volume is a constant, you cannot measure the leak accurately if both Pressure and Volume are changing at the same time during the test. The Pressure Decay is however perfectly suitable for rigid packaging. The AlphaLab is using the “Flow Measurement at a Constant Pressure” method according to DIN 55508-1 of 01/02/2018, particularly adapted to flexible packaging.

2/ Who can assist me if anything goes wrong?

We can assist you by remote video conferencing if there is no Service Company in your area / Country. We can do it during normal office hours and we are located in Singapore (GMT + 8 time zone). We can always support you outside of normal working hours with prior arrangement.

3/ Is there a risk that the package will be perforated totally, and the perforating pointer be damaged?

No, it is not mechanically possible that the perforating pointer will come in contact with the base, as it will stop 1 mm before.
