description

The rotary evaporator utilizes stepless speed regulation to rotate the glass flask at a constant speed, forming a uniform, large-area liquid film on the flask’s inner wall. Under vacuum conditions, the rotating flask is uniformly heated by an intelligent constant-temperature water bath to enable high-speed evaporation. Vapors are then efficiently cooled by the glass condenser and collected in the receiving flask.

features

1. Over-temperature safety protection: The unit automatically powers off when the actual temperature exceeds the set temperature by 5℃.

2. Anti-dry heating protection: The machine shuts down automatically if the water level in the heating pot drops below the heating tube.

3. Power-off restart protection: After a sudden power outage and subsequent restoration, the machine will automatically stop heating.

4. All glass components are crafted from high borosilicate glass (GG-17), offering superior high-temperature and corrosion resistance.

5. Main body constructed with stainless steel + aluminum alloy, featuring a rational structure optimized for material stress distribution.

6. Sealing system combines imported fluororubber and Teflon for two-way sealing, delivering long-term corrosion resistance, extended service life, and sustained high vacuum levels.

7. Vertical three-tier serpentine coil condenser paired with primary + secondary dual condensers to guarantee high solvent recovery rates.

8. DC brushless motor ensures stable rotation, spark-free operation, and gradual torque increase for smooth performance.

9. Electric bath lifting system incorporates a deceleration motor, ensuring exceptionally smooth lifting and lowering processes.

10. Bath tank made of premium 304 stainless steel for corrosion resistance and durability; outer silicone layer enhances safety during high-temperature operation.

11. Oil-filled vacuum pressure gauge with anti-vibration properties displays real-time vacuum levels.

12. Check valve control enables continuous discharge, allowing vacuum state switching while the machine is in operation.

13. All valves adopt the latest single-handle wheel design, providing excellent sealing and simplified, intuitive operation.

14. Supports continuous feeding via a valve-type feeding valve equipped with a PTFE tube assembly.

15. Collection bottle features a discharge valve, simplifying collection and discharge of evaporated extracts.

16. Full LCD screen offers dual digital readouts for temperature and rotation speed; bath pot constant temperature control uses a PT100 sensor for fast, accurate temperature transmission.

17. Microcomputer-controlled power switch for reliable and straightforward operation management.
