When Standard Rotary Evaporators Aren't Enough - Challenge Accepted!

October 2025

Heidolph Author: Heidolph

The starting point of a real laboratory challenge:

"Dear Heidolph team, we are running a large chromatography in which a fraction is collected in up to 800 liters of solvent (a mixture of ethyl acetate and hexanes), which then needs to be evaporated. Currently, we perform this evaporation using a 20-liter rotary evaporator. This process, however, is very labor-intensive and requires constant attention. […] I am interested in possibly equipping the lab with one of your automated 50-liter rotary evaporator systems but would like to learn more first.”

EFFICIENT EVAPORATION – BALANCING SCIENCE AND PRACTICE

Evaporation, condensation, recovery – this physical cycle forms the heart of every rotary evaporator. Heat, rotation, vacuum, and condensation work together precisely to separate substances and deliver pure results. Whether in research laboratories or on an industrial scale, rotary evaporation enables controlled processes and maximum efficiency – from small samples to large batches in the pharmaceutical, chemical, or food industries. That’s research made easy – with solutions that simplify your laboratory routine.

When Standard Isn’t Enough

Solvent removal and sample concentration are key applications in chemistry. Yet, as volumes increase, so does the need for automation: precise control of pressure, temperature, and rotation speed ensures reproducible results and the highest substance quality.

Our customers demand greater efficiency – and we gladly accept the challenge.
