Ai SolventVap 2L rotovap (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. Thats 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 or is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.

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.
A rotary evaporator(rotovap) 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).
Rotary Evaporator Frequently Asked Questions
-
Q: What type of plug is needed for my rotary evaporator?
A: The type of plug will depend on the model of rotary evaporator and whether the unit is a 110V or 220V model. Please consult the table below for further details:

Q: What is the temperature range of the rotary evaporator
A: The temperature range of the rotary evaporator is 20-99C.
-
Q: What is the maximum pressure that the glass condenser’s coil is rated to? What is the maximum pressure that the condenser itself is rated to?
A: The glass condenser’s coil is rated to 14 psi and the condenser itself is only rated for atmospheric pressure and a vacuum of 3 torr.
-
Q: What is the dual receiving flask kit used for on the 20 and 50L rotary evaporators?
A: The dual receiving flask kit is used to remove reclaimed solvent from the evaporator without interrupting its operation.
-
Q: What heating medium can be used in the water bath?
A: Only distilled water can be used as a heating medium in the water bath of an Across International rotary evaporator.
-
Q: Can the vacuum level be set on the rotary evaporator?
A: The vacuum level can be set only when a vacuum controller is purchased with the rotary evaporator. Please speak to sales or check the rotary evaporator’s customization section on the website for recommendations.
-
Q: What accessories come with the purchase of a rotary evaporator?
A: The accessories that come with each model will be different depending on the unit purchased. An accessories list can be found on the unit’s website listing and can be found in the standard package tab.
-
Q: What is the evaporation speed of my rotary evaporator?
A: The evaporation speed of the rotary evaporator will depend on what is being evaporated, and the parameters chosen. Please refer to the table for the estimated evaporation rate for ethanol and water.
