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.

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.
D-SUB Vacuum Feedthroughs
D-Sub Vacuum Feedthroughs are universal connectors that enable you to connect from the outside towards the inside of your vacuum chamber. We carry a large list of D-subminiature connectors for your vacuum applications such as the 9 pin, 15 pin, 25 pin, 37 pin, and 50 pin or a combination of any described.
