UHV (Ultra High Vacuum)

Ultra High Vacuum (UHV) refers to a space where the air and gas molecules have been removed to extremely low pressures, typically below 10^-9 pascals. Achieving UHV involves sophisticated pumping and cleaning methods to eliminate nearly all particles, creating a virtually empty environment. This is crucial for scientific experiments and industrial processes that require minimal contamination, such as electron microscopy or surface science, because it allows precise control over conditions, reduces interference, and improves the accuracy and quality of results or device performance.
