description
The rotary evaporator utilizes a stepless speed-controlled glass rotating flask that spins at a constant speed, dispersing materials into a large, uniform thin film across the flask’s inner wall. An intelligent constant-temperature water bath delivers uniform heating to the flask; under vacuum conditions, solvents evaporate rapidly, are cooled by a high-efficiency glass condenser, and are ultimately collected in the receiving flask.

features
1. Optimized structure with premium components: The mechanical framework primarily integrates stainless steel and aluminum alloy parts, while all glass elements are fabricated from high-temperature resistant high boron glass. Key electrical modules are imported, and rubber seals meet international standards for convenient procurement and replacement.
2. PTFE + fluororubber sealing cover maintains stable high vacuum levels, with built-in gas-liquid separation to prevent backflow.
3. Dual primary and secondary high-efficiency condensers ensure exceptional solvent recovery rates.
4. Equipped with a digital, continuous temperature-controlled water bath for precise thermal management.
5. Rotating flask features a nut-type connection for effortless installation and removal.
6. A tap valve positioned beneath the receiving flask enables rapid draining of recovered solvents.
7. Supports continuous material feeding for uninterrupted operational workflows.
8. Integrated vacuum gauge allows adjustment of optimal operating vacuum levels, making it ideal for handling low-boiling-point materials.
