Hei-VAP Expert Control rotary evaporators allow central control of all process parameters: Vacuum, cooling temperature, rotation and heating bath temperature. The units have separate knobs for quick access: Right for direct vacuum control, the left one for rotation has a lock function to prevent accidental adjustment

• 5" touch display for controlling the entire system including the vacuum and the cooling temperature
• For precise monitoring, the pictogram on the display also illustrates active functions
• Set values either via the touch display or the separate quick access knobs
• Direct access to two favourites on the start screen
• Expandable solvent library. Transfer your own favourites to other devices using a USB stick
• Define and save own evaporation processes (ramps) as favourites
• Automatically evaporate with the Dynamic AUTO_accurate Program (DAA). Convenient and customisable: From foam avoidance to highly efficient evaporation
• USB and Micro SD interface for easy installation of software updates and transfer of individual favourites from one device to another

The Automatic evaporation with Dynamic AUTO_accurate (DAA) allows the user to start a fully automated distillation process during the heat-up phase of the heating bath. The system vacuum is dynamically adjusted to the changing heating bath temperatures until the heating bath has reached its defined temperature. The boiling points of one or more fractions are identified through the steam temperature gradation of the mixture during continuous automatic pressure control. User can freely select if one or more fractions are to be distilled, vacuum control is fully automated for each fraction. Control the evaporation speed by adjusting the ratio of steam temperature to cooling temperature. Automation with sensors ensures noticeably higher precision. To protect the sample, the models with a motor lift automatically remove the evaporating flask from the heating bath at the end of the process.
