Chemical Vacuum Experiments on Gasses and Liquids

Did you know that gasses and liquids and even solids behave differently at different absolute pressures? For Example, water will start to boil at a lower and lower temperature as the pressure is decreased. Water can boil at room temperature if the pressure is decreased to 20 Torr of absolute pressure. Other phenomenon which can happen is that materials can fuse together or weld in high vacuum.

Our client is in academia performing research on Gas Phase and Liquid Phase Experiments. They required a large vacuum chamber that has a spring supported lid. The also asked us to provide them with an electrical NEMA-15 outlet so that they can power up some of their electrical devices inside of the vacuum chamber without compromising the vacuum.

In addition to the above, they requested a 25 Multipin Vacuum Feedthrough. This feedthrough along with the electrical outlet are placed on the rear wall. Finally, they requested 6 x 1/2 inch NPT liquid or gas vacuum feedthroughs that are placed on the remaining 4 exposed walls of the chamber. We plugged these feedthrough ports so that our client is able to remove the plug and hook up their liquid or gas line onto the port and run it into the vacuum chamber. The port is threaded from both inside and outside.

Acrylic Vacuum Chambers
Acrylic Vacuum Chambers are, as the name implies, vacuum chambers made from the Acrylic Polymer. There are several advantages to acrylic vacuum chambers the three main ones being 1. Fully Transparent, 2. Cost Effective, and 3. Versatile and Highly Customizable.
Thermocouple Vacuum Feedthroughs
Thermocouple Vacuum Feedthrough are air-tight components that enable the measurement of temperature inside the vacuum chamber during vacuum operations. If you have to run thermocouple wires into the vacuum chamber in order to measure temperature of a specimen during vacuum operation, a thermocouple vacuum feedthrough will enable you to do that.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
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.
