Rotary evaporator for solvent evaporation

Achieve precise solvent recovery and concentration control with this rotary evaporator, essential for processes requiring gentle thermal treatment and efficient volatile compound evaporation.

Facilitates Evaporation, Crystallization, and Drying Processes

The QVF® ROTADEST from De Dietrich Process Systems is a versatile rotary evaporator designed for industrial applications in pharmaceuticals, fine chemicals, and bio-pharmaceuticals. This unit excels in gentle but efficient evaporation, crystallization, and drying of liquids, powders, and granules. Utilized in applications such as active pharmaceutical ingredients and synthetic amino acids, it handles operations ranging from batch to continuous, even in EX-rated zones. Featuring a rotating spherical flask made from corrosion-resistant borosilicate glass 3.3, the ROTADEST allows for effective thermal treatment with minimal energy consumption, owing to its electrically heated, height-adjustable bath. It ensures optimal mixing and evaporation rates through its seamlessly integrated PTFE-lined drive system. Configurable for semi-continuous and manual control, it includes advanced instrumentation for precise monitoring and logging, with EX-rated versions available for hazardous environments. The unit supports seamless integration into existing production lines with materials adhering to FDA guidelines, ensuring high chemical compatibility and straightforward cleaning, aided by its mechanical design and optional CIP systems.
