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.
