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.

Did you know that we carry a many more products?

Our clients prefer to work with us because we are Experts in Vacuum Science and Technology. Check out some of our other items we carry that you can combine/integrate with your systems or projects.

Portable Vacuum Chamber and Pump Systems
We carry a wide range of portable vacuum chamber and pump systems. A Portable Vacuum Chamber and Pump system is placed onto a frame structure and lockable swivel casters which enable you to move your vacuum chamber and pump system around your facility. Our portable vacuum systems are very popular among businesses that are constantly growing, evolving, or sharing. Our portable vacuum systems are moved with ease from location to location.
Roots Blower Vacuum Pumps
Roots Blower Vacuum Pumps are used when a large amount of Volumetric Airflow is Required. Root Vacuum Pumps cannot operate independently and must be used in conjunction with another roughing pump such as Rotary Vane Pump or Piston Pump. The advantages of a Roots Vacuum Pump is that the Pumping Speed can be increased by a factor of 5 up to a factor of 10; meaning that a 20 CFM Rotary Vane Vacuum Pump can now be boosted to pump 120 CFM!
Our Work: Modified 14 inch Cube Vacuum Chamber for Degassing
This custom job was a modification to our standard acrylic vacuum chambers. When it comes to working with the Us Military, they want all specs to be met 110% and they want it yesterday. The military does not mess around which is why they came to us since we know how important it is to meet specs and ship fast.
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.
