After the second world war, advertisers were looking for attractive signs that worked at night. Vacuum provided the answer – neon lighting. It was a revelation in the 1940s, adding some brightness after years of conflict.
Decades of experience and collaboration with major scientific instrument manufacturers ensures Edwards have a clear understanding of the role vacuum plays across all analytical techniques. Using leading edge vacuum technology, our high quality vacuum pumps and controllers provide a clean vacuum environment with enhanced performance and excellent reliability.
Operation under vacuum is fundamental for many scientific instruments, especially those which use electron or ion beams as the core of their analytical or imaging techniques. Low pressures allow charged particles to travel and interact with samples unhindered by collisions with air molecules. Vacuum also provides the highest levels of chemical, thermal and electrical isolation and (for ultra high speed centrifuges) eliminates air friction.
Vacuum-based instruments include:
Edwards is a technology leader in the manufacture of vacuum pumps, gauging and systems with products specifically designed to meet the evolving challenges of new techniques and more cost effective instruments. With more than thirty years of experience in scientific applications, we have a deep understanding of the role that vacuum plays at every step. This experience, coupled with innovative technologies and collaborative engineering, enables us to offer a broad range of vacuum solutions that reduce cost while enhancing performance.
Edwards has been a leader in moving this market to drypumps as an environmentally superior alternative to the standard oil-sealed rotary vane pumps. Being oil-free, and with the pump bearings isolated from the pump swept volume, the risk of vacuum contamination is eliminated and ease of maintenance is improved, especially with regards to the need for compliance with environmental regulations when disposing of used oil.
