What is a Vacuum Chamber and How Does It Work?

Vacuum chambers are often the central point of technical research environments where test settings need to be totally clean – even at a molecular level.

A vacuum is a low-pressure space where all matter that could affect a testing or manufacturing process has been removed. In a vacuum chamber, air and pressure is removed from a confined, metal enclosure. This creates an ultra-clean setting where the performance of applications for manufacturing and scientific processes can be examined.

For example, space and aerospace industries often use vacuum testing to re-create the atmosphere in space and measure how components respond. The benefit of vacuum chambers is their ability to simulate environmental conditions and assist industry in developing their products – all while maintaining a process that is absolutely clean.

Vacuum chambers are designed to fit the unique needs of highly progressive industries

Entirely configurable and often created to bespoke requirements, vacuum chambers help to advance engineering and manufacturing competence across numerous sectors, including:

–

Research and Industry Material analysis Synchrotrons Material deposition Semi-conductor Mass spectrometry OEM science industry   … and more.

Standardised ranges of configurable chambers are made available for convenience – often in bell jar, ball, pill and cylindrical shapes. However, there are countless possibilities, and a vacuum chamber can be fabricated to suit the precise industry it services; be that a standard configurable chamber for science or a customer box chamber for deposition.

There is also the option to include additional services such as bake out and residual gas analysis respectively, this to improve the cleanliness and prove the vacuum integrity of the chamber.
