A rotary evaporator (Rotovap) is a piece of machinery or equipment used in the creation of some cannabis concentrates. A rotary evaporator evaporates and recovers pricey ethanol from ethanol-extracted concentrates. Rotary evaporators are one of the key steps in creating butane hash oil (BHO) and other cannabis concentrates.
Rotary evaporators, sometimes called rotavaps, are used in research and laboratory facilities to distill or concentrate solutions. Rotary evaporators rotate a solution that is placed in a heated bath. A vacuum is used to remove the evaporated fluid, which is processed and returned to a liquid for analysis. .
Compared to other evaporation processes the unique process feature of rotary evaporators is their ability to evaporate all volatile media providing at the end a dry product in the flask. The process conditions are limited by the maximum temperature of the heating bath ( max. ~ 160°C), the temperature of the cooling liquid (e.g. ~ 15°C tap .
Rotary Evaporators IKA rotary evaporators set new standards for safety, efficiency and ease of use. These rotovaps offer excellent distilling solutions to the demanding user. All IKA RV 10 rotovapors are equipped with a motorized lift with safety stop function. The comprehensive safety features also include interval operation, smooth start, end .
The evaporation technique is usually associated to chemistry but in the recent years celebrated chefs have been using rotary evaporators in their kitchens and less famous chefs are now doing so too. In spite numerous, and inevitable, initial perplexities it seems it .
