Rotary evaporators are devices 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.
The Ai SolventVap 1.3-gallon/5L rotary evaporators come with all PTFE valves for solvent-resistant operations. Also included are vertical glassware and digital temperature/rotation control. Its optimized bath volume allows for rapid heat-up times. That’s why Across’s 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.
- No chiller needed, utilizes dry ice for optimal efficiency.
- Solvent-resistant PTFE and Viton gaskets, ensuring long time operation.
- 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 for 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.
