This however applies only for small amount of water and only water.

A rotary evaporation or rotavap or rotovap uses precise engineering to effectively remove solvents from a sample using evaporationMost rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system increasing evaporation efficiencyIn many commercial labs these machines need.

What the Stretta procedure does is use radio frequency energy much like you see on the spectrum of harmless radio wavesThe energy is well controlled by the device to keep the temperature low enough to not damage tissueWhat it does do is stimulate the water molecules within the muscle tissue in the lower esophageal sphincter to vibrate.
