Rotary Evaporators Rotovaps Supplier - Ecodyst

Jun 07, 2021 New rotovap models often feature vapor temperature sensing and digital controls for vacuum pressure, temperature and rotational speed. However, despite incremental changes over the last 60 years, the basic operating principles in today’s conventional rotary evaporators remain the same as they ever were.

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...
