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

acrylic vac chamber for tests on lithium ion batteries
Front view of the scientific test chamber
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.

Vacuum Bubble Emission ASTM 3078 Leak Testing Systems
Bubble Emission (ASTM 3078) Leak Testing Systems are instruments that are used during the Quality Control process discover and locate leaks or seal integrity failures. Leaks are detected by submerging the specimen into a tank of water, applying a vacuum, and inspecting the submersed specimen for bubble emission. Our Bubble Leak Testing Systems are designed and built to conform to the ASTM D3078 protocol standard.
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: Vacuum Storage of Pharmaceutical Products and Medical Supplies
A pharmaceutical manufacturer contacted us to build them a large vacuum storage system for their pharmaceutical products. They were looking for as much footprint as possible which is why they got a two-chamber system from us. They needed a total of 6 shelves per chamber including trays. Finally, they were looking to have both chambers to be placed on a table frame assembly with lockable swivel casters. What you are seeing is a two chamber system, each chamber is our 20 inch cube acrylic vacuum chamber, front load hinged door. Each chamber can be accesses independently while the other is under vacuum. The trays can be easily loaded and unloaded. This whole system can also be moved to anywhere in their facility.

Visual inspection is an attractive option because it does not require the purchase of any additional equipment. There are several arguments against Visual Inspection of heat seals; the argument against visual inspection is that visual inspection is subjective, unreliable, operator dependent, or not a valid method of inspection. However, if you have the correct training, procedures, and documentation in place, visual inspection can become a powerful tool in your quest for better packaging.
