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. However, careful application also allows for the 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.
Example: The following table is a list of a variety of substances ordered by increasing vapor pressure (in absolute units).
Ai SolventVap 0.5-gallon/2L (evaporating flask capacity) series rotary evaporators come with a modular
heating bath, 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 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 99°C (210°F) with PID temperature control stepping
at 0.1°C 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 0.13
gallon (0.5L), 0.26 gallon (1L) or 0.53 gallon (2 liters) pear shaped
evaporating flask, 0.26 gallon (1 liter) round-bottomed receiving flask, and
vertical condenser. Rotary evaporators with vertical glass condenser are
great for distillation of solvents with higher boiling points.

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.
