Description The cooling water cycle machine is a fully enclosed refrigeration system, combined with PID control, the cooling is fast and the temperature is stable. It is used in various laboratories and production fields to meet different cooling and constant temperature requirements. It is mainly used for atomic absorption spectrophotometer, plasma emission spectrometer, scanning electron microscope, high frequency fusion machine, glove box, plasma etching machine, rotary evaporation, direct reading spectrometer, molecular distillation, Kjeldahl nitrogen analyzer and other products. The chamber provides an economical and environmentally friendly cooling cycle solution. Humanized design, small size, very quiet when working, can be placed on the desktop or used in the ventilation window. Equipped with rotary evaporator: used in many fields such as chemistry and pharmacy in various colleges and universities across the country, local disease control centers, inspection and quarantine, food and drug quick inspection projects, and pharmaceutical factory R&D departments. Mainly used for concentration, extraction, drying, separation and crystallization experiments.
