Feb 16, 2019 Why Rotary Evaporator Glassware Implodes and the Dangers. Of course, the desired effect of pulling vacuum on your rotovap setup is to reduce the pressure inside the system. However, the reduced pressure creates a suction effect on the inside of the system components. This can result in implosion of glassware.

Feb 25, 2021 What is Rotary Evaporation? Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

Freeze-drying sample preparation; Cannabis applications; Gin applications; And there are several things to consider when checking if your rotary evaporator is well equipped to deal with your specific application. For example, rotary evaporators are often compatible with various condenser types (see image below).

Make sure your evaporator is clear of any splash zones. Flat, Vibration and impact-free location. Vibration can cause hot liquids to splash and your sample to become contaminated or lost into the collection apparatus. Impact can damage the rotary evaporator and cause malfunctions in case of emergency shut-down. Clearance.

Mar 11, 2019 Small Sample Sizes (Painstaking vs. Painless) Working with rotary evaporators can be difficult, especially with small samples. Transferring the solvent to the rotovap, followed by painstakingly scraping the sample from the round-bottom flask, not only leads to wasted effort, lost time and loss of sample, but also presents risk of cross-contamination.
