Zhengzhou Greatwall Manual Lift 500ml, 1L, 2L Rotary Evaporator

Brief Introduction of 500ml,1L,2L 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 500ml,1L,2L (evaporating flask capacity) series rotary evaporators come with a modular heating bath, vertical glassware, and digital temperature/rotation control, with optimized bath volume allows for fast heat-up times. The condenser unit has special designed glass tubes that utilize surface extremely efficient. That’s why our SolventVap delivers reliable and reproducible process results that are usually reserved for more costly systems. Another important aspect of the SolventVap are the safety features, including dry-run protection, water bath over-temp shut-off protection, and fuse protection.

Rotary evaporator features a specially designed motor and worm gear to provide 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 that is effected by heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum. This reduces the boiling point of the solvents and removes the vapor phase making the process much more efficient. Each unit is also provided with an easy to use vacuum release and a continuous feed system, which allows more solvent to be drawn into the rotating flask without the need 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. Built-in overheat protector shuts down power in case of controller failure.

Standard Glassware Set 0.5L, 1L or 2 liters pear shaped evaporating flask, 1 liter round-bottomed receiving flask, and vertical condenser. Rotary evaporators with vertical glass condenser for are good for distillation of solvents with higher boiling points.
