- Stand-Alone Concentration System



The AccuVap EVS™ Evaporation System is a fully automated way to concentrate offline samples ranging in volume from a few to hundreds of milliliters of solvent. The AccuVap EVS™ can replace more manual evaporation methods like kudera-danish and rotary evaporation. The AccuVap EVS™ has quantitative transfer, unlike other semi-automated evaporation systems. A new way to concentrate! The AccuVap EVS™ combines gentle heat and vacuum to concentrate large volumes of solvent. Precise control devices monitor solvent volume, temperature and vacuum to ensure controlled evaporation.
