Rotary Evaporator and Smart Evaporator
Differences between Rotary Evaporator and Smart Evaporator
Smart evaporator removes DMSO
Rotary evaporator is more efficient for most of solvent. The Smart Evaporator evaporates and removes better high boiling point solvents such as DMSO, DMF and Water. In addition to that, Smart Evaportor has an advantages on small volume and precious samples regardless the type of solution. A traditional Rotary Evaporator works better for others.
Rotary evaporators are widely used in chemistry laboratories for solvent removal including high boiling point ones 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 concentrating process.
With a rotary evaporator, the solvent is placed under full vacuum in order to lower the boiling point, and heat is applied to the sample for the evaporation to occur. While effective, these conditions can lead to superheating, which 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. Nevertheless, 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 or splashing to occur in the evaporation process, since samples are never under full vacuum. Blowing is common way to remove solvent. Putting a needle or pipette tips to a hose coming from a tank of inert gas such as helium, nitrogen, or argon gas. However, 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.
