When the American, award-winner, chemical researcher Lyman C. Craig invented the rotary evaporation system in 1950, probably he could not imagine what an innovation he brought into the chemical and pharma industries. For sure he could not imagine that rotary evaporators could be used even in modern “molecular cooking”. Compared to a static apparatus, the vacuum rotary evaporator can carry out single stage distillations quickly and gently. The capacity of a rotary distillation is generally about four times greater than a conventional static distillation, therefore no surprise about their widespread success. Evaporation is a common and important step in many research and development applications. The concentration of solutions by distilling the solvent and getting rid of low and higher-boiling or solid residue is a necessary step in organic synthesis and extracting inorganic pollutants. Evaporators are also used outside research laboratories such as chemical, pharma, petrochemical and food industries.
