Leybold Ultra-high Vacuum Applications:

National laboratories, large universities and industries all utilize a wide range of vacuum equipment to achieve required levels of vacuum.

Many of these organizations rely on us for highly-specific vacuum pumps, instruments, and systems.

UHV is the vacuum regime characterised by pressures lower than about 10⁻⁹ mbar (10^-7 Pa).

Ultra-high vacuum conditions are necessary to reduce surface contamination in many surface analytic techniques. For example X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), secondary ion mass spectrometry (SIMS) or field emission microscopy (FEM).

Thin film growth and preparation techniques with stringent requirements for purity, such as molecular beam epitaxy (MBE) and atomic layer deposition (ALD), also rely on UHV conditions.

In research applications like particle accelerators or gravitational wave detectors ultra-high vacuum conditions will mainly help to reduce beam-gas interactions and limit undesired perturbations from the outer environment. These vacuum levels demand the use of special materials and pumping principles.

We offer a broad range of advanced vacuum solutions for use in ambitious UHV applications. Our components, system solutions and after sales services have shown their benefits in major research centers worldwide.
