Rotary Evaporator, also known as rotovap, is a laboratory device used for efficient and gentle removal of solvents from samples by evaporation. It allows researchers to concentrate, separate, and purify compounds under reduced pressure and controlled temperature conditions.

Recirculating Chiller is a cooling system used to maintain low temperatures in the rotary evaporator's condenser. It circulates coolant, such as water or a refrigerant, through the condenser coils to remove heat generated during the evaporation process.

Diaphragm Vacuum Pump is an oil-free, efficient pump used to create a vacuum in the rotary evaporator system. It operates using a flexible diaphragm that moves up and down to create suction, drawing out air and vapor from the rotary evaporator's vacuum flask.

The rotary evaporator, chiller, and diaphragm vacuum pump are commonly used together as an integrated rotovap system in labs. The combined use of these three devices forms a closed-loop system that enables efficient solvent evaporation and concentration. The rotary evaporator creates a controlled evaporation environment, while the chiller ensures efficient condensation of the solvent vapor, preventing loss of valuable compounds. The vacuum pump facilitates the creation of a vacuum, enhancing the evaporation process and enabling higher sample recovery rates.
