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.

Pressure Decay Leak Testing Systems
Pressure Decay Leak Testing Systems are instruments that detect and quantify a leak by measuring the pressure drop over specified amount of time. Any specimen that is inflated will stay inflated if it is leak tight. On the other hand, of a leak exists in the inflated specimen, air will escape through the orifice and decrease the pressure inside the specimen. The higher the pressure drop, the high the leak.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
Our Work: Leak Quality Testing and Quality Control of Packets
Quality Control during Production runs is a very important procedure you must perform on your manufactured products. This is especially critical is you are an FDA manufacturer where regulatory compliance is important and necessary. Our Vacuum Chambers are specifically built to assist you meet your Quality Control and Regulatory compliance needs.
