Nowadays, packaging materials are utilized popularly to package a variety of items. These products include liquids, solids, gels, powders, and other similar items. It is critical that the seal of these items' packaging is totally intact so that the product does not leak out of the packing and there is no chance of any external impact interfering with the products. Thus, a vacuum leak tester is helpful in detecting any sort of leaks in a variety of products manufactured as per your industry. The vacuum leak tester is a precise testing instrument offered by Testronix Testing Instruments that is used by many packaging industries and Pet manufacturing industries for testing the quality of the pouches and PET bottles. This amazing lab testing instrument offers high-quality precision and measures vacuum leaks accurately. Here in this blog, we will discuss how you can easily operate this lab testing equipment efficiently. But before that, we will discuss a brief about vacuum leak tester and how this testing instrument is beneficial for your testing pouches and PET bottles.

Introduction about vacuum leak tester

For many packaging companies, leaks will have a bad impact on the quality of materials. Even a small hole will lead to oxygen from the air entering the packet faster in a package which can deteriorate the product quality. Bacterial growth accelerates, posing a danger to the product quality. The Vacuum Leak Tester is a widely used testing equipment that is used for testing integrity of the foiled cups and other packaging products to the effect of vacuum. This testing instrument is highly helpful in assuring that the seals of packaging materials are intact and do not have any leakage or damage.

During the testing procedures, the test sample is placed in its place and then a specified amount of vacuum is created in the sample. After the vacuum is created in the sample, it becomes easy to test any leakage in the test sample with great accuracy. When the test specimen is placed under vacuum, if there is a leakage in the seal of the specimen, it will deform or shrink indicating the presence of leakage in the specimen. The vacuum leak test is performed in order to ensure that the packaging offered to the clients is free from any leakage and is completely intact. This lab testing equipment has been made in accordance with industrial standards like ASTM D 4991-07(2015), ASTM F 2338-09(2013). Take leak measures if you want to be certain that the bottles you offer will be of the highest quality.

By using this quality vacuum leak testing instrument you will be able to eliminate the problem of vacuum leakage. Below we have listed the features and technical specifications of this lab testing equipment.

Steps to operate vacuum leak tester

Testronix vacuum leak tester is one of the dependable testing instruments that offer quality control measures to packaging applications. This is one of the most innovative testing equipment available for identifying vacuum leaks in a wide range of items.

To operate this package integrity tester efficiently, you can follow the below-mentioned steps:

  • First of all, turn the machine on by plugging the main socket of the machine into a 3 pin 15 amp socket.
  • Set the test duration timing on the digital timer.
  • After setting the digital timer, remove the desiccator cover and place the test specimen inside the desiccator.
  • After placement of the Specimen, put the cover back on the desiccator.
  • Make sure that the cover is properly placed on the gasket. If the cover is not properly placed, there will be no buildup of vacuum inside the desiccator.
  • Once you place the specimen accurately then turn the inlet knob to a close position.

Once you follow all the above steps, you can easily commence the test. Before starting the test, ensure that the pressure adjustment valve is in the closed position.
