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 illustrates a variety of substances, ordered by increasing vapor pressure (in absolute units).
Ai SolventVap 1.3-gallon/5L (evaporating flask capacity)
series rotary
evaporators come with all PTFE valves for solvent-resistant
operations. Also come with them 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. 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 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 cover enhances 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.
· One year warranty on rotary evaporator except glassware and all sealing gaskets.
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.
