Submersion Leak Testing of Explosive or Volatile Products

Ever wondered how to leak test packaged volatile products? Do you know that there are countless unstable products out there that have to be leak tested as part of quality control? By volatile we mean products which ignite, explode, shatter, melt, or are hazardous. Keep in mind that hazardous material for whatever reason has be undergo quality control as well.

This is what our client wondered too. They wondered how to perform a quality leak test on their volatile product safely. They came to us because we manufacture clear acrylic vacuum chambers which are incorporated into Bubble Leak Testing Systems. As with many of our happy clients, we will not be able to tell you what exactly they were doing as that information is proprietary. However, we will be glad to show you what we made for them and how it helped them.

What we built for them is a Large Bubble Leak Testing System. The Acrylic Tank Dimensions are 25 inch Wide, 14 inch Deep, and 18 inch High. The Lid is hinged and supported by a Gas Spring which will keep the lid open in order to enable the operator to load the tank with test specimen without having to hold the lid with one hand. We also provided them with a 6 CFM Uniweld Vacuum Pump and a Vacuum Pump Protection Valve. This protection valve will prevent tank water from accidentally entering and damaging the vacuum pump. We also provided them with an Instrutech Digital vacuum gauge to enable them to have better vacuum readings from their bubble leak testing system. There is also a drain valve which comes with every one of our bubble leak testing systems. Finally, if you look closely, you can a hole cut out into the right wall. Our client asked us to cut this hole because they wanted to connected a rotary feedthrough to it so that they can manipulate the test specimen from the outside during vacuum operations. This whole system is placed onto table frame structure with lockable swivel casters making this a portable bubble leak testing system.

Vacuum Decay Leak Testing Systems
Vacuum Decay Leak Testing Systems are Instruments that detect and quantify a leak by measuring the drop in vacuum (pressure) inside the specimen. During a vacuum decay leak test, the specimen is placed into a vacuum chamber, the vacuum is pulled to a specified setpoint, and the drop in vacuum is monitored and recorded over time. If a leak in the specimen exists, the air will travel from a higher pressure (inside the specimen) to a lower pressure (vacuum chamber). As a results of the additional air, the vacuum levels will drop whereas a leak can be detected and quantified.
Viewport Vacuum Feedthroughs
Viewports Vacuum Feedthroughs are windows that enable you to look into the inside of your vacuum chamber. If you are using a metallic vacuum chamber with a metallic lid, you will not be able to view the interior of your vacuum chamber unless you have a viewport. Viewports also enable a different electromagnetic spectrum of light to passthroughs.
Our Work: Vacuum Storage of Pharmaceutical Products and Medical Supplies
A pharmaceutical manufacturer contacted us to build them a large vacuum storage system for their pharmaceutical products. They were looking for as much footprint as possible which is why they got a two-chamber system from us. They needed a total of 6 shelves per chamber including trays. Finally, they were looking to have both chambers to be placed on a table frame assembly with lockable swivel casters. What you are seeing is a two chamber system, each chamber is our 20 inch cube acrylic vacuum chamber, front load hinged door. Each chamber can be accesses independently while the other is under vacuum. The trays can be easily loaded and unloaded. This whole system can also be moved to anywhere in their facility.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
