1, water bath heating: the heating system is heated in the form of water bath, the temperature is set to room temperature -100℃ (medium water), the time can be adjusted according to the boiling point of the reagent, room temperature needs to be adjusted, the temperature is fast, the heat is uniform, so as to ensure the temperature of the extraction process is stable, which helps to improve the accuracy of the experiment.

2, built-in cooling water circulation: the cooling method adopts a closed internal circulation reflux system, without external cooling water source, one-key internal circulation water tank to add water, to avoid waste of water resources, equipped with a compressor cooling internal circulation system, suitable for mass work, condensation effect is good.

3. Extraction system: The extraction system uses the Soxhlet extraction principle to repeatedly soak the sample for extraction. During extraction, the sample to be tested is wrapped in a defatted filter paper package and put into the extraction tube. The organic solvent in the extraction bottle is heated and vaporized, rising and condensing, and drops into the extraction tube, so the cycle is repeated until the extraction is complete.

4, end point automatic control system: digital display temperature controller, intelligent end point control, heating extraction temperature and time can be set at the same time, built-in professional PID temperature control system, can make the temperature control accuracy is less than 1℃, the extraction time to automatically stop heating, the end of the experiment, no personnel on duty.

5, grinding connection: all the glass parts used in the instrument are glass grinding joint, to avoid the use of sealing rings due to organic solvents and deformation leakage caused by personal safety problems.

Dehumidifiers reduce air humidity by cooling the moisture in the air so that it condenses into water droplets. it is suitable for humidcimate, basement, bathroom. kitchen and other humid environment. can effectively prevent mold, bacteria arowth, and improve thecomfort of living and working environment.
