The vacuum sealing machine/system is mainly used to achieve oxygen free and anhydrous vacuum sealing preservation and high-temperature solid-phase synthesis of samples. The entire system consists of a vacuum sealing machine, a hydrogen oxygen machine, a molecular pump system, a quartz tube, connecting joints, etc. Standardized customized quartz tubes and quartz columns ensure precise matching of other specially designed tube joints, thereby further improving the sealing performance of quartz tubes and achieving higher standards of vacuum sealing.
