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.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
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: Submersion Leak Testing of Explosive or Volatile Products
Ever wondered how to leak test packaged volatile products? Do you know that there are countless unstable products out there that have to be leak tested as part of quality control? By volatile we mean products which ignite, explode, shatter, melt, or are hazardous. Keep in mind that hazardous material for whatever reason has be undergo quality control as well.
