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.

Altitude Package ASTM D6653 Leak Testing Systems
Altitude Package (ASTM D6653) Leak Testing Systems, or Testing Systems which test the effect of higher altitude on packages are vacuum systems that consist of a vacuum chamber, a vacuum controller, and a vacuum pump. The goal of these package testing systems is intended to test and investigate the effects of higher altitudes on the seal integrity, package quality, or container closure integrity.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Pressure and Vacuum Chamber used for Calibration of Weather Stations across the US
Have you ever wondered how the weather forecast works? You must admit; the weathermen (or weatherwoman) have become a whole lot more accurate over time. 10 years ago, the weather forecast was not as accurate as it is today. Part of the reason is that we have better forecasting technology as in more powerful computers who crunch numbers faster to out a most likely scenario. Another reason is that mathematics, physics, and science has progressed. The main reason however, is that we have better tools and equipment.

In this article we will talk about Vacuum Pumps - but also about other equipment which is used to produce vacuum inside a closed system or chamber. We will talk about the workings of a vacuum pump, vacuum generation, pump down, pump horsepower. This article is intended to provide you a practical guide which should help you select the appropriate vacuum pump for your system.
