The Rocket Evaporator uses a patented new technology, which works like this:

 

Samples are placed in special evaporation flasks, put into the rotor, spun, and placed under vacuum (point B), as they would be in any other vacuum evaporator. By pulling a vacuum on the samples, the solvent(s) will boil at a low temperature, which is set by the pressure. Dri-Pure technology stops any bumping and cross contamination.

 

To achieve the dual goals of very fast evaporation with very precise temperature control to protect valuable samples, low temperature, low pressure steam is used to heat the sample flasks directly. In turn, the steam condenses on the flasks, which are cold due to the solvent(s) boiling inside them. Condensate is thrown off the spinning flask, where it is recycled and boiled again to make more steam. The heating arrangement is optimal, eliminating potential sources of energy loss.

 

Steam temperature is controlled in two ways:

To keep the two vacuum environments separate and to make sure that steam does not enter the flasks, they are sealed into the rotor. Each flask slides effortless into its holder and the action of spinning the rotor firmly seals it in place.
