Vacuumtechnik
Vacuumtechnik, or vacuum technology, is the engineering and science of creating and maintaining low-pressure environments in which gas molecules are significantly reduced. It encompasses the physical principles of gas flow, surface outgassing, materials selection, seal technology, vacuum equipment, instrumentation, and process control for a wide range of applications.
Vacuum levels are described by pressure and are commonly expressed in units such as pascals, millibars, and
The generation of vacuum relies on pumps and collection methods. Positive-displacement pumps such as rotary vane
Applications span semiconductor manufacturing, thin-film coating, electron microscopy, vacuum furnaces, degassing and distillation, mass spectrometry, and
