A High-Performance and Versatile Rotary Evaporator
The BÜCHI Rotavapor R-114 is a rotary evaporator designed for laboratories requiring an efficient solution for solvent evaporation. It operates on a proven principle that combines controlled rotation, adjustable temperature, and vacuum operation to accelerate the distillation process while minimizing thermal stress on samples. By facilitating evaporation, it enables researchers and technicians to optimize their distillation, concentration, and purification operations.
This model features a rotating evaporation flask partially immersed in a heating bath to create a thin film that maximizes heat contact surface area. Solvent vaporization is thus promoted before it is condensed in a cooler connected to a receiving flask. Through this mechanism, the Rotavapor R-114 ensures optimal yield while preserving the integrity of the substances being processed.
The device is designed to meet the demands of each user. Its manual lift system, called Quick-lift, allows for easy adjustment of the evaporation flask's height, providing controlled immersion in the heating bath. The integrated motor, equipped with a stepper drive, ensures uniform and adjustable rotation over a wide range of speeds, from 5 to 240 revolutions per minute. This flexibility allows for modulating the process intensity based on the properties of the solvent being evaporated.
The efficiency of the Rotavapor R-114 also relies on precise temperature control, a fundamental element for ensuring the quality of distillations. It is compatible with various heating baths, operating with water or oil, and offering thermal regulation ranging from 20 to 180 °C depending on the model used. This precise heat control allows for adjusting parameters according to the specifics of each application, particularly in the fields of organic chemistry, pharmacy, and complex substance analysis.
One of the main advantages of this evaporator lies in the diversity of available glassware, allowing for performance optimization based on solvents and experimental conditions. Various condenser configurations are offered, including diagonal, vertical, cold trap, or reflux versions. This modularity provides great adaptability to user needs, whether performing simple evaporation or more complex processes involving the recovery and separation of specific components.
Safety was a particular focus in the design of the Rotavapor R-114. The device is equipped with an automatic stop feature to prevent excessive immersion of the flask in the heating bath, thus avoiding any risk of overheating or uncontrolled boiling. The robustness of its sealing system ensures optimal tightness, minimizing leakage risks and ensuring reliable use. To provide additional protection, the glassware is made of high-quality borosilicate glass, a material known for its resistance to thermal shock and aggressive solvents.
Durability is another strength of the Rotavapor R-114. Manufactured with resistant materials, such as an aluminum alloy housing and PTFE components, it is designed to withstand intensive use while minimizing wear on parts in contact with solvents. Its maintenance is facilitated by a modular design, allowing for simplified access to various parts of the device for cleaning or replacing worn elements.
