Solvent evaporation and concentration of active substances are essential steps in the drug discovery process.

Rotary evaporation is used for synthesis, development, sample preparation, solvent recycling and scale-up production on the quest to novel therapeutics.

Our industry-leading rotary evaporation solutions cover the complete sample range and are ideal for simple scale-up from lab scale to production scale projects. A high degree of automation and cutting-edge design combine to offer reliability and convenience in the pharma R&D laboratory.

Parallel evaporation enables sample throughput of 4 to 96 samples per batch with sample amounts ranging from 1 to 500 ml per sample.

We are market leaders at laboratory vacuum evaporation, where you can concentrate samples with sizes between 1 and 2.5 L.

BUCHI can also support you with industrial-scale evaporation of up to 20 L in batch-wise or continuous operation mode.
