A rotary evaporator, or rotavap, is a piece of equipment that efficiently and gently removes volatile solvents from your product through evaporation. The main components of a rotavap are: An evaporation flask, which contains the sample material. A motor that rotates the flask. A vacuum-sealed vapor pathway, which draws vapor off the sample

Any component SpeedVac system can be configured with either an oil-free diaphragm pump or rotary vane oil pump. We generally recommend oil-free technology for all applications except freeze-drying (which requires the deeper vacuum achieved with an oil pump) and evaporation of high-boiling-point solvents such as DMSO.

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Dec 16, 2019 Connect one socket to the rotovap (where the evaporation flask would usually go). You can secure it in place or hold it with one hand. Note, the flask should not be set to spin during this process. Use your thumb to close the second socket of the two-neck flask. Set the vacuum pump to around 250 mbar and switch it on.

Feb 14, 2022 Rotary evaporators (rotovaps) are devices employed for removing solvents efficiently via the process of evaporation. The rotary evaporation process is one of the most widely used methods of solvent evaporation due to its optimal extraction and distillation performance. Rotary evaporators are also used for concentration, crystallization, drying ...

good correlation with the evaporation rates observed for the in-line evaporator.9 Removal of high boiling solvents such as water, DMF, DMSO, pyridine and N-methyl-2-pyrrolidone (NMP) is extre-mely slow and consumes large amounts of energy using stan-dard rotary evaporators. In a typical reaction work up it is

Jan 01, 2020 Rotary evaporation is a powerful technique for quickly removing solvent from a solution of cannabis or hemp extract. There are two distinct methods of operating a rotary evaporator: batch or continuous; choosing the correct one for the task is crucial. For the purposes typically required in the cannabis industry, i.e. winterization or color ...

Mar 12, 2021 First, 10 g of concentrate were added to a 1 L eggplant flask for the rotary evaporator, and then the DMSO solution containing copper chloride was added. The solution was prepared by dissolving two equivalents of CuCl 2 and NaCl (78.7 mmol) in 200 mL of DMSO. The stoichiometric ratio of Cu in the concentrate to the initial cupric ion in the ...

rotary evaporation rotavap controlled-evaporation processes. Samples dissolved in DMSO cannot be as easily recovered compared to other solvents, as it is very difficult to remove all traces of DMSO by conventional rotary evaporation. Solvents with higher boiling points such as water (100 C at standard atmospheric pressure, 760 torr or 1 bar ...

Sep 30, 2021 Step 2 – The solvent is heated and stirred constantly to ensure that it arrives at the necessary temperature which is below its boiling point at room temperature. Step 3 – a chemical reaction takes place and manipulates the substance to begin the evaporation of the liquid. The vital solvent parts are separated from the waste and the waste ...

Thin films of lipids are prepared by rotary evaporation from solutions in dichloromethane (CH 2 Cl 2).The lipid film is rehydrated with an aqueous solution of the reactant and/or other additives and agitated at a temperature above T c until the film has completely detached from the flask (Fig. 12.4).This results in the separation of the lipid sheets, which close on themselves to form a ...

When working with rotary evaporators, the separation of high-boiling solvents such as DMSO or DMF is often difficult. The substances tend to condense again in the vapor tube and are therefore difficult to transfer into the receiving flask. Three things are especially important in this case: An absolutely leak-proof rotary evaporator system, a ...
