Extracting scents & smells

Chimica Oggi-Chemistry Today

Genevac evaporator systems are widely used by researchers seeking to safely extract novel fragrance molecules from natural sources. To obtain fragrances from natural products – chemists and perfumers often employ organic solvent extraction techniques to produce a large volume of crude extract. This technique is preferable to steam distillation as the higher temperatures are prone to denaturing the delicate fragrance molecules and some materials do not yield their characteristic aroma using steam. Using a patented low temperature technology, the Genevac Rocket™ vacuum evaporator has become a defacto standard for safely concentrating crude extracts while preserving delicate fragrances. To isolate individual fragrance components from the concentrated extract, one or two dimensional chromatography is then often the technique of choice. Rocket Evaporators use patented vacuum technology to evaporate solutions to dryness, or to concentrate, rapidly and safely.
The latest Rocket Synergy evaporators offer integrated, flexible solutions for processing a wide range of sample volumes. Interchangeable rotors will accommodate tubes, flasks and batch volumes of up to 100 litres.
