A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure.

Rotary Evaporator DOVMX-RE1005-5L
RE1005-5L旋转蒸发仪 （旋转瓶5L，收集瓶3L）
Applications
Large capacity and large opening of evaporating flask give larger evaporation surface. The evaporating flask keeps rotating when it is constantly heated by water bath, and solvent evaporates more efficiently under vacuum condition. It can be used for pilot-scale production in biology engineering, pharmaceutical industry, chemical industry and food processing. It usually works with water circulating vacuum pump, diaphragm vacuum pump, recirculating chiller, constant- temperature circulator, low temperature circulating pump, etc.
Advantages
- Patented technology of double sealing of Teflon(PTFE) and FV rubber ensures the negative pressure level.
- Automatic switch valve makes continuous collection possible without affecting vacuum degree and without stopping distillation
- Teflon discharge valve is corrosion resistant and contamination free
- Water bath jacket protecting operator from scalding by hot liquid

DOVMX 5L series rotary evaporators
All DOVMX come with all PTFE valves for solvent-resistant operations. Also come are vertical glassware and digital temperature/rotation control. Its optimized bath volume allows for rapid heat-up times. The condenser unit has specially designed glass tubes that utilize surface area extremely efficiently. Thats why our DOVMX evaporators consistently deliver reliable and reproducible process results that are usually reserved for more costly systems. Another important aspect of the DOVMX is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.
Rotary evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 180 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process much more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system, which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation.
Digital water bath operates from ambient temperature to 99C (210F) with PID temperature control stepping at 0.1C increments. Heating coils are located directly inside the pan for the most efficient heating possible. A built-in overheat protector will shut down power, should the controller fail.
Standard Glassware Set includes 1.32 gallon (5 liters) round-bottomed evaporating flask, 0.79 gallon (3 liters) round-bottomed receiving flask, and vertical condenser. Rotary evaporators with vertical glass condenser for are great for distillation of solvents with higher boiling points..
Features
- Solvent-resistant PTFE and Viton gaskets, ensuring long time operation.
- Water bath coverenhances safety by protecting evaporating flask and the material inside; it gives you uniform temperature inside evaporation flask as well as energy saving by reducing heat loss. It also creates a better lab environment by preventing heat and humidity from escaping.
- Specialized motor with extremely compact, intermeshed worm and worm gear provides precise driving for very quiet, vibration-free operation.
- Downward-condensing vacuum connection design ensures safe vacuum operation.
- Motorized water bath lifting for precise control.
- Easy, straight-forward visual operation with digital speed and temperature display.
- PID temperature controller ensures accurate temperature control is maintained.
