description
Primarily deployed for concentration, crystallization, drying, separation and solvent recovery within pharmaceutical, chemical and biopharmaceutical sectors, the explosion-proof rotary evaporator operates on the following principle: under vacuum, the rotating flask is heated at a constant speed, causing the material to spread into a large-area film on the flask wall for efficient evaporation. Solvent vapor is then cooled via a high-performance glass condenser and collected in the receiving flask, significantly boosting evaporation efficiency. This system is particularly well-suited for concentrating and purifying heat-sensitive biological products prone to decomposition and denaturation at elevated temperatures.

features
1. Comprehensive explosion-proof protection is integrated across the system, including explosion-proof aluminum enclosures for the variable frequency speed control module and control panel, as well as explosion-proof tubing for cable routing.
2. Variable frequency speed control with an explosion-proof switch is included, and a precision-adjustment knob allows for accurate speed regulation, with real-time revolution count displayed.
3. A combined sealing system of polytetrafluoroethylene and fluororubber ensures consistent maintenance of high vacuum levels.
4. The integrated vertical condenser features a double-layer serpentine coil design, guaranteeing high solvent recovery rates.
5. All material-contacting components are constructed from high borosilicate glass (expansion coefficient 3.3) and polytetrafluoroethylene, ensuring stable performance and excellent chemical inertness with processed materials.
6. The main support frame is fabricated from aluminum alloy with cold-plate anti-corrosion coating for superior corrosion resistance, while the bath vessel is made of stainless steel, delivering a compact, durable and aesthetically polished structure.
7. A pointer-type vacuum pressure gauge provides real-time vacuum level readings for clear monitoring.
8. The piston-type feeding valve is equipped with an extended PTFE tube, enabling continuous material feeding into the evaporation flask under vacuum conditions for operational convenience.
9. The constant temperature bath features digital temperature display, paired with a K-type sensor and stainless steel probe for rapid and accurate temperature transmission.
10. The bath vessel can be raised via a hand wheel, ensuring straightforward and user-friendly operation.
