The XcelVap® Evaporation/Concentration System Pressure Profiling
8 Aug 2014Programmable pressure profiling in an evaporation system allows the gas pressure to be gradually increased as the evaporation cycle progresses. This application note describes the pressure profiling feature of the XcelVap® evaporation system and the advantages it provides when compared to evaporation at a constant pressure.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Evaporators and Freeze DryersCentrifugal evaporation is used for solvent removal from a sample. This is a useful technique for sample concentration or sample drying. Many centrifugal evaporators are modular with a central vacuum pump for generating low pressure. Useful features of evaporators or vacuum ovens include minimal solvent bumping, solvent resistance, computer control, temperature regulation and benchtop design.Pressure ControlSample ConcentrationSample concentration involves the removal of solvents from samples using technologies such as centrifugal evaporation, lyophilization and rotary evaporation.
