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.

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: Electronic Component Testing of Satellites at High Altitudes
Electronic Components of Satellites behave differently in outer space as compared to how these behave at sea level. How do you know that your satellite will survive outer space? How do you confirm that your circuit boards will function properly at higher altitudes? There is only one way to find out, and that is to test and validate your design.
