Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials

acrylic vac chamber for tests on lithium ion batteries

This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

As you can see, they requested that the vacuum valve and the vent valve be placed on one side of the wall. Then they requested two more 1/4 NPT ports to be placed on the opposite side of the valves. Finally, they asked as to provide them with a total of four 50 Ohm Matched Impedance for High Frequency Transmission to 6 GHz, Air-side Connector Included, Grounded Shield, UHV Compatible feed through to be placed on the two remaining walls. In the end, we had two ports on each wall for a grand total of 8 ports.

The nice thing about these ports is that these are the standard NW16 and NW25 ports consisting of the same industry standard bolt pattern. The advantage of our ports is that they are interchangeable with any other NW flanges, centering rings, and can be clamped with a standard NW Bulkhead clamp; or any other ISO quick flange for that matter.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Bubble Leak Testing System with a Dry off Sink used for Leak Testing Large Bags
How do you leak test Large Food Bags? This is the same question a Large Food and Beverage Processor had asked themselves because they had need for a bubble leak testing system which could be used to detect presence of leaks in their large bags. Their requirements were to test several sized bags with the largest bag being 24 inches Wide by 12 inch Deep by 9 inches High. In addition to the bubble leak testing system, they also needed a way to dry the bags after the test.
