Vacuum chambers are devices for removing gases including air from an enclosed space. The air is sucked out of the enclosure using high performance vacuum pump and the chamber has to be sealed to a high degree to prevent ingress of air using silicon gaskets which do not degrade and are resistant to chemicals. The chambers are used in industrial as well as scientific applications and are capable of maintaining their vacuum seal for days at a time.
