What is the purpose of a rotary evaporator?

The purpose of a rotary evaporator is to transform liquid samples into gas. It’s primarily used for concentrating solutions, purifying substances, and recovering solvents in chemical laboratories. It works by evaporating the solvent and leaving behind the solute, thus increasing the concentration of the sample. Additionally, it’s commonly employed for sample preparation, especially for compounds requiring concentration or purification. Overall, a rotary evaporator is a versatile tool facilitating concentration, purification, and solvent recovery in chemistry labs.

Why is a rotary evaporator better?



It speeds up the evaporation process by rotating the sample at the bottom of the flask, making the solvent evaporate more readily, thus improving evaporation rate and efficiency.



Thanks to its efficiency, a rotary evaporator can complete solvent evaporation in a shorter period, saving experimental time.



Rotary evaporators typically come with temperature and vacuum control features, allowing precise control over temperature and pressure during evaporation, facilitating precise sample handling.


Solvent recovery

It efficiently recovers solvents, reducing experimental costs and aiding environmental protection.


Sample protection

Since the evaporation process occurs at lower temperatures and under vacuum conditions, it effectively protects volatile components in the sample, reducing sample loss and alteration.
