A common basic operation in the organic chemistry laboratory is the removal of a volatile organic solvent from a reaction mixture or a process such as liquidliquid extractionAlthough this operation could in principle be performed by simple distillation the fastest and most convenient method is the use of a rotary evaporator rotovap for distillation under reduced pressure.
Dec 19 2018nbsp018332GallardoWilliams plans to launch the set of labs in fall 2019 as fully distance educationbased organic chemistry lab courseIn addition to the virtual reality labs the team also produced a Matterport virtual tour of the Fox Hall lab and instrument roomsThe tour incorporates the NC State Organic Chemistry SMART videos produced during a.
Dec 20 2019nbsp018332A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed and the mixture can form a film on the inner surface of the flask creating a larger surface for heatingAll of these factors contribute to the faster evaporation speed of solvent which means higher efficiency and better accuracy.

Even though the rotary evaporator or rotovap for short looks pretty complicated its really pretty simpleThe purpose of the rotovap is to remove low boiling organic chemicals usually solvents from a mixture of compoundsThe rotary evaporator is the method of choice for solvent removal in the modern organic laboratory.
GallardoWilliams initially started thinking about this project to serve populations of students who cannot attend the inperson labs for various reasonsThere are students who may become pregnant and cannot complete the lab students who deploy in the military during the semester and students with disabilities that make it more difficult to complete the lab.

Jul 21 2017nbsp018332Understanding Rotovap DistillationBefore learning about rotovap setup and operation you must have a clear picture of the physical change happening inside of the rotary evaporatorConsider how a mixture containing extract and ethanol must first be separated before rotovap distillation can occur.

Mar 05 2021nbsp01833256A Overview of Rotary EvaporationIt is very common for a desired compound to be dissolved in a solvent during regular manipulations in the laboratoryThe preferred method for solvent removal in the laboratory is by use of a rotary evaporator also known as a quotrotovapquotA rotary evaporator is essentially a reduced pressure distillation a.
Organic laboratory techniques 8 8The rotary evaporator or quotrotovapquot is an expensive piece of apparatus that needs to be used with great careIf you follow the instructions carefully it is the fastest most efficient and most environmentally friendly way of removing a volatile solvent from a nonvolatile sample.
Pearshaped recovery flask is usually used as boiling type flasks for rotary evaporators.
Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higherboiling point compound of interestThe rotary evaporator or rotovap was invented in 1950 by the chemist Lyman CThe primary use of a rotovap is to dry and purify samples for downstream applications.

The purpose of this experiment is to explore heat transfer using a simple coffee cup calorimeterTwo separate processes will be examined one that transfers heat to the surroundings and one that absorbs heat from the surroundings.
The rotary evaporator is the method of choice for solvent removal in the modern organic laboratoryThe solvents or low boiling compounds are removed by a simple distillationThe rotovap is designed to be operated under a vacuum to lower a compounds boiling point while heating the sample at the same time.
The TAs are not actors but TAs who have taught the lab many times before in the same lab roomThe TAs cover diverse populations and are examples of the people you’d encounter every day on NC160State’s campusThey’re similar and relatable to undergraduate students.
To put it simply the rotary evaporator commonly known as rotaevaporador is an apparatus which is designed to remove and separate low boiling organic compounds and chemicals from organic inorganic and polymeric materials along with compound mixtures through evaporation.
We take advantage of this in our use of the rotary evaporator or rotovapThe diagram below is a generic rotary evaporatorThe rotary evaporator is used for removing a solvent well below its boiling point leaving behind the lessvolatile material that was dissolved in that solvent.
With these populations in mind as well as goals of a studentfocused and inclusive experience GallardoWilliams and the DELTA team set out to produce a series of five virtual reality organic chemistry labs.
A 360° camera is basically treated like a person meaning it sees everything that you would see if you were physically standing in a space said Instructional Media Producer Arthur EarnestIf you look down you see a body when you8217re lifting test tubes it8217s ‘your hands’ lifting the test tubes and when the TA is talking they are talking directly to you.
