Rotary evaporator system which is kept in Nano-biomaterial laboratory. Scope: This device is applicable for evaporation and solvent extraction of samples, and should not be used for irrelevant cases. Responsibility: Laboratory assistance is responsible for the accuracy of the device and should be reported to him/her in case of problems.
remember for solvent removal via rotary evaporation is the 20/40/60 Rule. These numbers refer to the D20ºC principle. Since Buchi invented the Rotary Evaporator 50 years ago, Buchi has continued to make advancements to the Rotavap as well as vacuum pumps and controllers. The newest controllers from Buchi feature not only a large
The final requirement for an evaporator, then, is a means of separating the evaporated water vapor from the evaporator liquid. This part of an evaporator is called the vapor body. These two main components, the heat exchanger and the vapor body, are connected together to form an evaporator. Almost all evaporators operate in the same way.

Mar 11, 2019 · Bumping vs. No Bumping. Bumping is a common problem while using rotary evaporators, as samples being heated under vacuum in closed conditions causes the solvent to suddenly boil and "bump," in other words erupt, usually quickly without warning.As the rotovap evaporates the solvent under vacuum, the solvent can be sucked up in its entirety, leading to the loss .
Rotary Evaporator Bumping Problem. The Problems Come With Rotovap Bumping. Bumping is one of the problems associated with a rotary evaporator. When it bumps it will lead to an unnecessary solvent lost. This shows that just as the process has great advantages that are associated with it, there are also some negative aspects of it as well.
