OGMaster7842 degassing station is a pretreatment equipment with excellent performance. Designed for sample pretreatment procedures for physical/chemical adsorption or other analyses. Pretreatment refers to heating the sample in a vacuum environment to remove impurities adsorbed by the sample. These impurities may be adsorbed on the sample when placed in the air, or introduced during sample preparation. The presence of these impurities may affect the physical properties of the sample or sample testing. It can run fully automatically without manual intervention after startup. Equipped with a large touch LCD screen intelligent temperature and pressure control system, which can be used for sample tubes of different diameters at the same time.
