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.

Some of our Popular Items

Our clients prefer to work with us because we are Experts in Custom Fabrication (especially Polymer Fabrication). There is a tremendous amount of valuable resources and information regarding vacuum systems and vacuum technology; check them out by clicking on the links below.

Vacuum Oven Systems
Vacuum Ovens are vacuum chambers and ovens combined in one system. Vacuum ovens are necessary during processes which require the specimen to be subjected to a hypobaric and hyperthermal environment. Our Vacuum Oven Systems enable to you run a complete vacuum vs time and temperature vs time profile. We also carry portable vacuum oven systems and custom vacuum oven systems.
Belt Drive Rotary Vane Vacuum Pumps
A Belt Drive Rotary Vane Pump is almost identical to a Direct Drive Rotary Vane Pump. The only difference between the two is that the belt drive Rotary Vane Vacuum Pump is driven by a belt. There are several advantages why a belt drive vacuum pump would be preferable. One of these reasons is that the belt drive Rotary Vane Vacuum Pump runs at a slower RPM therefore the temperature created is lower, the wear and tear is less, and the overall lifetime of the pump is longer. The disadvantages are a lower CFM and performance.
Our Work: Altitude Testing in a Vacuum Chamber
It is not a secret that you can simulate a certain altitude in a vacuum chamber. The good thing about Acrylic Vacuum Chambers is not only that you can simulate an altitude of up to 250,000 feet, you can also fully view your test specimen during your testing operation.
Related Articles: Force Decay Leak Testing
Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
