Rotary Evaporator

Differences between Rotary Evaporator and Smart Evaporator

Smart evaporator removes DMSO

Rotary evaporator is more efficient for most solvents. The Smart Evaporator evaporates and better removes high boiling point solvents such as DMSO, DMF and Water. Also, Smart Evaporator has advantages on small volume and precious samples regardless of the type of solution. A traditional Rotary Evaporator works better for others.

Rotary evaporators are used in chemistry laboratories for solvent removal. Including high boiling point solvents and sample concentration by using heat and vacuum. The Smart Evaporator is not intended to replace rotary evaporators. As rotary evaporators are still needed in many situations when concentrating samples. With the Smart Evaporator, you don’t need to worry about bumping during concentration of high boiling point samples. You may walk away during the concentrating process.

With a rotary evaporator, the solvent is under full vacuum to lower the boiling point. Heat is applied to the sample for the evaporation to occur. While effective, these conditions can lead to super-heating. This triggers rapid boiling, or “bumping” in your solvents. With the risk of cross-contamination upon bumping, this can lead to complete loss of the sample. Still, a rotary evaporator is a must have item for any organic chemistry lab. In conclusion, you need both types of evaporators.

No Bumping by Smart Evaporator

In contrast, the Smart Evaporator has no risk of bumping. There is no splashing in the evaporation process, since samples are never under full vacuum. Blowing is a common way to remove solvent. Putting a needle or pipette tip to a hose coming from a tank of inert gas such as helium, nitrogen, or argon gas. But, this method has drawbacks as well, as it is time consuming and leads to splashing. The Smart Evaporator provides a more elegant solution. By offering a hands-free evaporation process without the risk of bumping or splashing.
