5.5B: Step-by-Step Procedures for Rotary Evaporation ...
A single-effect evaporator as shown in Fig.1 is wasteful of energy since the latent heat of the vapor leaving is not used but is discarded. However, much of this latent heat can be recovered and reused by employing multipleeffect evaporators. A simplified diagram of a - forward-feed tripleeffect evaporation sys- tem is shown in Fig.2.

The rotary evaporator or "rotovap" is an expensive piece of apparatus that needs to be used with great care. If you follow the instructions carefully, it is the fastest, most efficient and most environmentally friendly way of removing a volatile solvent from a non-volatile sample. It is standard equipment in a modern chemistry laboratory. The ... What are rotary evaporators? A rotary evaporator (or rotavap or rotovap) uses precise engineering to effectively remove solvents from a sample using evaporation. Most rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system, increasing evaporation efficiency.. In many commercial labs, these machines need to be running around-the-clock without ...

Glass Rotary Evaporator Flask - IndiaMART
The first TASTE evaporator was designed and built by Ralph Cook in 1960 as a improved high temperature evaporator. The TASTE evaporator produced a stable concentrate with little heat damage. By the mid 1960’s TASTE evaporators were the standard evaporator in Florida. Other evaporators have been tried, plate evaporators (low quality juice and ... falling film, forced circulation flash, and multiple effect can add to the confusion. In this article we will take a brief, not-too-technical look at the most common types of evaporators, how they work, and some of their applications. The basic task of an evaporator is simple: to remove water from a solution or slurry by evaporation.

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

How to use a Rotary Evaporator
A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal. In a flash type evaporator, heated salt water passes through an orifice into an area of lower pressure which is created by an air ejector or vacuum pump. A portion of the water flashes into steam, and the steam passes up to a vapor separator, where water droplets are removed, and then to a distilling condenser where the vapor is condensed.

Rotary Evaporator (Rotovap) - Dartmouth College
Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will cause the compound to decompose. All Hei-VAP rotary evaporators have a safety heating bath with overheating and dry running protection, ergonomic handles, double wall and an integrated spout . Universal heating bath for all flask sizes up to 5 l (no retooling required). The sturdy metal connection to the device’s base allows variable distances for the heating bath up to 200 ...
