A vacuum chamber is a sealed container from which air and other gases are removed to create a low-pressure environment. This process allows scientists and engineers to conduct experiments or tests without the interference of air molecules. Vacuum chambers are commonly used in various fields, including physics, materials science, and electronics. These chambers can vary in size and design, depending on their intended use. They are essential for processes like vacuum packaging, thin-film deposition, and space simulation, where controlling the atmosphere is crucial for accurate results and product quality.
