● Liquid crystal display controller, multiple sets of data displayed on one screen, menu-type operation interface, accurate and reliable temperature control, and the operation status of the instrument can be confirmed at any time.
● When the compressor is overheated and overloaded, the temperature of the bath solution is too high or too low, and the refrigeration system is overpressured, it will display flashing and buzzer alarming functions.
● The open bath can be used as a pre-freezing tank and a low temperature tank. It can be put into glassware and can be used for constant temperature experiments of acidic solutions and organic solutions.
● Open the bath cover, which is convenient for the experimenter to observe the condensate state in the bath in real time.
● The heat exchanger tube is made of 304 stainless steel, which is wear-resistant, not easy to break due to vibration, easy to clean, and convenient for experimenters to maintain.
● The front baffle is designed with magnetic adsorption, which can quickly open the cover to clean the dust on the condenser without removing tools.
● The compact structure design can meet the requirements of laboratories with small space.
● A circulating cooler can cool multiple rotary evaporators at the same time to meet the cooling effect. Realize a multi-purpose machine.
● The optional R488 communication interface is used for computer display or export of experimental data, which provides a strong guarantee for the storage and playback of experimental data.
