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.

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Digital Vacuum Gauge Instruments
A Digital Vacuum Gauge is an instrument which precisely measures a vacuum level inside a vacuum chamber. Unlike a rough dial vacuum gauge, which shows only where the vacuum chamber is roughly with an error of up to 3% (a high as 1 inHg) a digital vacuum gauge will show vacuum levels up to 3 significant figure in Torr and millitorr – this makes the digital vacuum gauge ten thousand times more accurate than the dial vacuum gauge.
Our Work: Research, Development, and Testing of Weather Balloons inside a Clear Vacuum Chamber
A wonderful company (more like one of the best companies in the world) which is currently involved with the research, development, and testing of high-altitude weather balloons, had a need for a vacuum chamber capable of achieving about 100 micro Torr (Micron) of ultimate Pressure for their testing environment. Fortunately, acrylic vacuum chambers are the perfect choice when it comes to Low, Rough, and Medium Vacuum.

In this article we will talk about Vacuum Pumps - but also about other equipment which is used to produce vacuum inside a closed system or chamber. We will talk about the workings of a vacuum pump, vacuum generation, pump down, pump horsepower. This article is intended to provide you a practical guide which should help you select the appropriate vacuum pump for your system.
