What is the purpose of using the rotary evaporator? - Lab ...

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Dust burnout is outstanding at every firing rate and the NOx and CO emission values are reliably below all limit values. NOx emissions are also especially low on water-tube boilers in combination with a muffle and multistage combustion air supply, often making secondary measures for reducing NOx (for example SNCR) superfluous.
