20L Rotary Evaporator - Professional Laboratory Equipment for Pilot-Scale Operations
Our professional-grade 20L Rotary Evaporator works very well for removing solvents on a small scale and concentrating samples. This system meets the highest safety standards and can handle your most difficult tasks thanks to its advanced engineering and precise controls. Our equipment makes sure that you always get the same results, whether you work in drug development, chemical synthesis, or study institutions.


What Makes Our Rotary Evaporator Stand Out?
Integrated All-in-One Design
Our system combines the main unit, heating system, cooling components, and vacuum pump into one cohesive package. This integrated approach eliminates compatibility issues and streamlines your workflow.
Superior Vacuum Performance
The excellent air-tight design features PTFE and Viton double sealing technology. This ensures optimal vacuum levels below 2.6mbar for efficient solvent recovery.
User-Friendly Operation
The easy-assembly design means you can set up quickly and start working immediately. The intuitive LCD display shows all critical parameters at a glance.
