What is an ultra-high vacuum component?

Ultra-high vacuum components are essential to many industries. Ultra-high vacuum (UHV) is the term used to describe a vacuum that is characterised by very low pressures of around 7-10 pascals. To create ideal UHV conditions, gas has to be pumped out of a UHV chamber. This enables free molecular flow of the gasses and gas molecules collide with the chamber walls and with each other. To make this possible, you'll need the very best in ultra-high vacuum components. That's where we come in. Our reputation for quality and efficiency has made us the first choice of customers all over the world who rely on us for outstanding UHV products and fast delivery.

Where are ultra-high vacuum components used?

MEWASA ultra-high components are often used in research or industrial settings. Typical uses may include vacuum tubes, composite plastic moulding, flight instruments, and medical applications. Equipment built with ultra-high vacuum components is employed in the lifting, rotating, holding, and moving of all kinds of parts and materials in manufacturing and industrial settings. We excel in the creation of ultra-high vacuum components for the research industry. For example, our specially developed pillow seals have gaps and air grooves that evacuate air and increase the pressure force. Our pillow seals are available from DN50 to Dn500 and high customer satisfaction means that we're still expanding our range. In scientific research, ultra-high vacuum components such as our UHV chambers or seals are used to achieve UHV conditions in areas such as X-ray photoelectron spectroscopy, auger electron spectroscopy and low energy ion scattering.
