What is a Rotary Evaporator?

The essential tool for solvent removal in modern laboratories.

A rotary evaporator, often called a "rotovap", is a specialized laboratory device designed for the efficient, gentle removal of solvents from samples via evaporation. It combines reduced pressure, controlled heating, and rotating motion for optimal solvent extraction while preserving sensitive compounds.

Rotary evaporators have become indispensable in chemistry, biochemistry, and pharmaceutical industries due to their ability to process solvents without damaging heat-sensitive materials.

Efficient Evaporation

Removed solvents 50% faster than conventional methods

Temperature Control

Preserves heat-sensitive compounds and materials

Enhanced Safety

Built-in safety features minimize operational risks

Versatile Applications

Works across multiple industries and solvent types

How Does a Rotary Evaporator Work?

Rotary evaporators operate on a sophisticated principle: samples in a rotating flask are partially submerged in a heated bath. The rotation creates an optimal evaporation surface area, while simultaneous vacuum pressure reduces the solvent's boiling point, enabling low-temperature vaporization.

Sample Loading & Rotation

The sample is placed in a rotating flask that increases surface area for evaporation

Vacuum Application

Reduced pressure significantly lowers the boiling point of solvents

Controlled Heating

The flask rotates in a water bath at precise temperature settings

Vapor Condensation

Solvent vapors travel to a cooled condenser for liquefaction

Solvent Collection

Liquefied solvent collects in a receiving flask for disposal or reuse

Why is reduced pressure important in a rotary evaporator?

Reduced pressure dramatically lowers the boiling point of solvents, enabling extraction at significantly lower temperatures. This preservation effect is critical for heat-sensitive compounds and improves both efficiency and compound stability.

Applications of Rotary Evaporators
