Difference Between Sublimation and Evaporation

Difference Between Sublimation and Evaporation

Apr 29, 2022 Key Differences. Sublimation is the conversion of matter from a solid phase to the gaseous phase without passing through the liquid phase, whereas evaporation is the conversion of the liquid phase into the gaseous phase. Solid-phase is the initial phase for sublimation while the liquid phase is the initial phase for evaporation.

What is a Rotary Evaporator? -

Feb 14, 2022 Rotary evaporators work on the principle that solvents have a range of boiling points, which decrease under reduced pressure. The evaporation flask rotates at a specified speed forcing the materials to form a large area of thin film on the inner wall of the flask. The flask is heated evenly, and materials with a lower boiling point rapidly evaporate. Recycling of the …

Rotary Evaporator (Rotovap) Issues and the Smart Solution

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.
