The fully transparent sapphire reaction kettle has two types: fully transparent and window. At the same time, it can be designed, customized and processed according to the user's experimental requirements. Fully transparent sapphire micro autoclave, pressure resistant, full volume visible. It is used for reaction visual research, sampling analysis, multiphase phase behavior observation, spray observation of supercritical particle preparation, thermodynamic property research, long-time dissolution process observation, etc. Fully transparent good light transmission, high-pressure visible, the whole experiment can be observed, and the temperature range is wide! Jacket temperature control, both high temperature and low temperature reaction can be done. Magnetic coupling mechanical stirring, static sealing, zero leakage.
