A Laboratory Rotary Evaporator (often referred to as a rotavap) is a laboratory device used for the efficient and gentle removal of solvents from samples by evaporation. It is widely used in chemistry and biochemistry labs for distillation purposes, particularly when dealing with temperature-sensitive compounds that could degrade or decompose at higher temperatures.

Key Features of a Rotary Evaporator:

1. Rotating Flask:

   • The core feature of the rotary evaporator is the rotating flask, which holds the liquid sample. The flask is rotated at a controlled speed to increase the surface area of the liquid, which enhances the evaporation process.

2. Vacuum System:

   • The evaporator is typically used in conjunction with a vacuum system, which lowers the boiling point of the solvent, allowing it to evaporate at lower temperatures. This is particularly useful for volatile compounds that would otherwise decompose at higher temperatures.
