Whether isolating subatomic particles or simulating the conditions of space, ultrahigh vacuum (UHV) and extreme-high vacuum (XHV) are at the center of the human search to understand the physical universe. The unique condition of such very low pressure—nearly devoid of matter—must be created using specialized equipment and techniques. Mastering the creation and maintenance of vacuum is critical to advanced research of the natural world.

Learn how ultrahigh vacuum plays a key role in advanced inquiries in physics.
Agilent has been supporting scientific inquiry enabled by ultrahigh (UHV) and extreme-high vacuum (XHV) for many decades and remains committed through continued innovation of vacuum technologies, products, and services.
Agilent provides robust, industry-leading turbomolecular vacuum pumps and controllers that deliver complete confidence across a broad range of applications. Agilent turbo pumps range from 70 to 2,300 L/s and feature innovative designs backed by exhaustive testing and trusted after-sales support.
Agilent ion pumps and controllers are available in several configurations to satisfy your vacuum requirements. They are the best choice for those applications where stable ultrahigh or extreme-high vacuum (UHV or XHV) conditions are essential, such as: laboratories, large research facilities, scanning electron microscopes, and surface analysis tools.
Agilent VHS and HS diffusion pumps have pumping speeds from 65 to 28,000 L/s, in an operating range of 1 x 10-3 Torr to 5 x 10-9 Torr. Our patented bulge body diffusion pump design maximizes pump throughput while delivering pressure stability and reducing backstreaming to a minimum, which is ideal for critical applications such as vacuum coating, roll-to-roll deposition, metallizing, brazing and heat treatment.
In vacuum systems, a rough vacuum is used as a preliminary stage before achieving ultrahigh vacuum (UHV). The process typically involves using a roughing pump, which operates at pressures above 1x10-3 Torr, to evacuate the system of most air molecules. This stage is crucial because pumps designed for UHV cannot operate at atmospheric pressures. Once the rough vacuum is established, UHV pumps take over to further reduce the pressure. The selection of the appropriate roughing pump, whether oil-sealed or dry, depends on factors such as the requirements for clean vacuum, and maintenance.
