CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF .

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.

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.

Rotary Evaporation - Chemistry LibreTexts

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 .

ORGANIC LABORATORY TECHNIQUES 8 8.1 ROTARY .

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 .
