Rotary Evaporator with 0.5-Gallon/2L

Rotary Evaporator with 0.5-Gallon/2L

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.
