Rotary Evaporator

Rotary evaporators for solvent recovery and gentle concentration under vacuum.

A rotary evaporator recovers solvent by spreading the liquid as a thin film over the inside of a rotating flask under vacuum. The large surface area and the reduced pressure let the solvent boil off well below its atmospheric boiling point, so the concentrate is never overheated and the recovered solvent can be reused.

Who This Equipment Is For

Extraction laboratories recovering ethanol from miscella
R&D teams concentrating an extract before analysis
Pilot lines producing small batches of crude
Quality control laboratories preparing samples

Problems It Solves

Solvent lost to the atmosphere instead of being recovered
Heat damage to the concentrate during evaporation
Slow evaporation from a still, unstirred vessel
No repeatable way to reduce a batch to a fixed volume

Key Benefits

Vacuum evaporation

Solvent boils off below its atmospheric boiling point, which protects the extract.

Thin film surface

Rotation spreads the liquid so evaporation is fast and even.

Solvent recovered

The condensed solvent is collected for reuse instead of being vented.

Bench to pilot

Sized for laboratory work and small pilot batches.

Specifications For This Line Are Quoted Per Project

Rotary evaporators are quoted by flask volume, bath type and condenser duty. Tell us the batch size and the solvent and a specification will be prepared.

Rather than publishing a model that would not match your process, the specification is written after two questions are answered: what raw material you will process, and what production capacity you need per batch. Machines are built from 0.5L to 200L, and larger capacity is customised on request.
