Vacuum pumps are versatile tools used across a wide range of industries and applications to create a vacuum by removing gas molecules from a sealed volume. Their uses span from industrial processes like vacuum packaging and drying to specialized laboratory tasks such as filtration, freeze drying, and mass spectrometry. Different applications require specific vacuum levels, ranging from rough vacuums for drying and distillation to ultrahigh vacuums for advanced scientific research like particle acceleration. In laboratories, vacuum pumps are essential for tasks like aspiration, cell harvesting, and solvent degassing, while in industrial settings, they are used for bottle filling, pick-and-place operations, and holding/lifting materials. The choice of vacuum pump depends on the required pressure level and the specific application.
