Developed largely as a consequence of users’ demands for an evaporator that could quickly process larger volumes of solvent in parallel and without supervision, the Rocket Evaporator is designed to dry or concentrate as many as six flasks, each containing up to 450ml of solvent. The user is able to focus on other tasks, confident that the Rocket will achieve perfect, reproducible results every time.
The key to this unique evaporation capability is a fundamentally new drying technology developed by Genevac engineers. It uses steam at low temperatures (such as 40°C) and vacuum to dry the samples, with the result that the process is up to five times faster than other technologies capable of unsupervised operation. Crucially, the Rocket Evaporator is also equipped with the advanced performance features that Genevac users expect, such as effective bumping and cross contamination protection, precise temperature regulation and very easy to use controls.
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.
