Brief introduction of 50L Rotary Evaporator:
A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporator is most often and conveniently applied to separate "low boiling" solvents such as n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure. However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation (azeotropic behavior), and a sufficient difference in boiling points at the chosen temperature and reduced pressure.
The Zhengzhou Greatwall 50L (evaporating flask capacity) series rotary evaporators come with 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. That’s why our SolventVap evaporators consistently deliver reliable and reproducible process results that are usually reserved for more costly systems. Another important aspect of the SolventVap 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 20 to 140 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 to 99°C (210°F) with PID
temperature control stepping at 0.1°C. 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 Glass ware Set includes 50 liters round-bottomed evaporating flask, 20 liters round-bottomed receiving flask, and vertical condenser. Rotary Evaporator with vertical glass condenser are great for distillation of solvents with higher boiling points.
Features of 50L Rotary Evaporator:
Your safety is important to us! Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
