A vacuum source is a device or system that creates a vacuum, which is a space devoid of matter, including air. This is often achieved by removing air or gas from a sealed environment, resulting in lower pressure. Vacuum sources are commonly used in various applications, such as in laboratories, manufacturing processes, and medical equipment. There are different types of vacuum sources, including vacuum pumps, venturi pumps, and suction cups. Each type operates on specific principles to achieve the desired vacuum level. These devices are essential in industries like pharmaceuticals, food packaging, and electronics for processes that require controlled environments.
