Extracting the Scents & Smells of Christmas
Genevac evaporator systems are widely used by researchers seeking to safely extract novel fragrance molecules from natural sources
8 Dec 2015
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.

Rocket 4D Synergy Large Volume Evaporator
GenevacRocket 4D Synergy is designed primarily to evaporate large sample volumes, with autofeed if required, allowing automatic evaporation of volumes up to 100 litres. Rocket 4D Synergy provides fast, safe evaporation for solvents with a boiling point of up to 165°C (DMF) and can easily dry aqueous samples. The system feeds the solution for evaporation to the evaporation vessel, controls temperature and pressure, prevents bumping and foaming, drains the condenser, stops when dry or concentrated, and if required, redissolves the product in a small volume of solvent, unattended, and with no user intervention. The Rocket 4D Synergy can also be fitted with a removable flask rotor to accommodate the full range of Rocket Sample handling solutions such as flasks, tubes and SampleGenie. Now you don't need to choose between flask or batch/feed evaporation. The Rocket and Rocket 4D Synergy evaporators will accommodate your process, whatever the volume. Each is capable of replacing several rotary evaporators and saving valuable bench space.
