Dec 18 2018nbsp018332The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding itIt also assumes the compounds in the liquid are thermally sensitive otherwise you could just boil the solvent outA rotovap works by creating a vacuum in a rotating glass flask.
Dec 20 2019nbsp018332A rotary evaporator rotovap or rotavap refers to a kind of equipment for solvent evaporation under reduced pressure which is composed of a vacuum system a heated water or oil bath a condenser and a motor that rotates the evaporation flaskThey cooperate with each other and all play an essential role in the working process of a rotary evaporator.
Feb 15 2021nbsp018332A rotovap or rotary evaporator is a device which is employed for the gentle and efficient removal of solvents from samples via evaporation and are typically used to remove solvents from a mixture of chemical compoundsRotovaps work on the principal that the boiling point of a solvent is substantially lower than the compound it is dissolved.

Zucchini is a delicious food that can be eaten on its own or added to other dishesThe easiest way to eat zucchini is to leave it rawHowever you might enjoy it better if you cook itZucchini can be steamed boiled baked sauteed or grilledIts also a great substitution for pasta If you want to add more zucchini to your diet you can also mix it into other recipes.
