Unrivaled Efficiency and Performance

-Dual condensers and dual receiving flasks, allowing for swift solvent recovery. 

-Pre-heating injection coil uses the heated bath to preheat your solution before spray injection into the flask and accelerates the evaporation speed by up to 150%, allowing the performance of a larger rotary evaporator with a smaller footprint. facilitating an astounding 12 gallons per hour recovery of alcohol-based solvents

-Convert the rotary evaporator from batch distillation into a continuous distillation with the vacuum injection valve which allows the user to continuously spray their solution into the boiling flask for improved efficiency by keeping the boiling flask full to match loss from evaporation. 

-Electric lift makes adjusting flask height as easy as pressing a button.

-Water level sensor turns off the heating elements if the water level is too low, preventing overheating and as a great safety feature

-Isolation valve allows for draining of receiver flask while retaining vacuum and distillation.


Intuitive Digital Control and Safety at Its Finest

Navigating through complex procedures has never been easier with our digital user interface. Seamlessly control the evaporation process with just a few clicks, while the automatic lifting motor smoothly elevates the flask for convenient handling.  Additionally, the flask holder secures the glassware when disassembled, reducing the risk of accidents and ensuring utmost protection.
