Mechanical rotation of a magnetic stirrer or a rotary evaporator can induce an enantiomeric excess of supramolecular species. In this study, we investigate the effect of fluid motion in a rotary evaporator on chiral supramolecular species. It is shown theoretically that the twisting effect of fluid motion on cylindrical particles is expressed in terms of helicity dissipation rate.
A bump trap, which is a secondary flask that is smaller than the main flask, is also often used during evaporation. This additional flask is placed right above the main flask so that if bumping occurs, the sample will get caught in the bump trap before getting drawn into the rest of the rotary evaporator .

= 1 atm abs pressure, the last effect will be under vacuum at a pressure P. 3. 3. Backward-feed multiple-effect evaporators. In the backwardfeed operation shown in Fig.3 for a triple- effect evaporator, the fresh - feed enters the last and coldest effect and continues on until the concentrated product leaves the first effect.
C. Multiple effect vacuum evaporators (MED) This technology comprises a series of mutually connected evaporators in which the vacuum steadily increases from first to last. This means that, in principle, the boiling temperature decreases, thus allowing the vapor generated in an evaporator (or effect) to be used as heating fluid in the following .
systems, the individual evaporators are called effects and the evaporator system is referred to as a multiple effect evaporator. The significant advantage of this arrangement is that it allows the original heat input to the system to be re-used in each effect. This greatly increases the thermal efficiency of .
Jul 16, 2016 · Problem: Rotary evaporators ("rotavaps") have for decades been staples in labs and industries performing chemistry, including labs in the chemical, environmental, materials, life science, and forensics industries. Key applications include sample concentration, solvent recycling, extractions, and separation of solvent mixtures. Rotavaps consist of a heating fluid bath, rotating motor .

Generally a rotary evaporator is a laboratory instrument applied in chemical and biology laboratories, as well as pilot plants, for the purpose of efficient evaporation of solvents. A vacuum system, a rotating evaporation flask, a condenser with a collecting flask, these components composed of a complete rotary evaporator.
With the increasing use of rotary evaporators, there are many merchants selling rotary evaporators on the market.Considering that everyone has some doubts when purchasing rotary evaporators, today I will give you some knowledge for purchasing rotary evaporators for your reference.Here's the latest rotary evaporator product of 2020, which can be compared with the old one.
In an evaporator handling an aqueous salt solution, the overall coefficient U(kW/m2 deg K) is given by a form of equation 14.14 as: 1/U2 = 7 ×10−5t b+0.2, the heat transfer area is 40 m2, the temperature driving force is 40 deg K and the latent heat of vaporisation of water is 2300 kJ/kg. If the down-time for cleaning is 15 ks (4.17 h), the .
Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and .
