Enzyme fermentation and reaction can be adjusted between ambient temperature +5 ° C / 99.9 ° C during operation such as tissue culture, bacterial incubation, etc., allowing for shaking of flour, flask and tubes in different sizes on the samples. The temperature and time setting are set digitally, with PID thermostat and LED indicator. • It has the ability to run at the set program temperature without being dependent on the time when requested. • The program values set for use of the device are not deleted when the device is turned off. It can be watched again when requested. • Liquid and vapor contact surfaces are corrosion resistant, easy to clean and provide homogeneous heating for testing at each corner of the appliance. • Balloon holders, bracket shelves or tube carriers that can carry glass tubes are optionally available. • It is practical and takes little space on the laboratory bench. • Convenient for overhead use, the water in the device can be easily drained with drain hose.
