1. Adopting a three-phase explosion-proof motor for variable frequency speed regulation, with digital display of speed, the motor has low temperature rise and low noise.

2. Patent sealing technology (patent number: 022640703), high vacuum, solvent resistant, able to maintain high vacuum. Gas-liquid separation, no reflux.

3. Adopting efficient dual condensers with main and auxiliary components to ensure high recovery rate.

4. The rotating bottle is connected with a nut for easy loading and unloading.

The R202F model adopts a 10L collection bottle, equipped with a new reinforced glass tetrafluoro fractionation switch. When discharging, the vacuum system of the collection bottle can be cut off, ensuring continuous evaporation work.

6. Continuous feeding is possible.

7. The vacuum system is equipped with a vacuum gauge, which can adjust the optimal working vacuum degree for low boiling point materials.

8. The water bath pot has electronic constant temperature control and can be lifted and lowered.

9. External vacuum pipes and water pipes are not directly connected to the glass, which can reduce accidental damage to the glass.

10. The entire machine is explosion-proof, certified by relevant national departments, with certificate number CLEx21.8804.
