Optimizing Büchi® Rotary Evaporator Applications

Introduction

Selecting the correct operating parameters for Büchi Rotary Evaporators is an important part of your application. Many variables must be considered, i.e. choosing the appropriate bath temperature, vacuum pressure, rate of evaporation, and accessory chiller—so it's no surprise to find more vapors collecting in the lab environment than in the receiving flask!

The following discussion offers a complete guide for optimizing your Büchi Rotary Evaporator application.

Choosing the bath and condenser temperature (20-40-60 Rule) The first topic of discussion is the 20-40-60 Rule. The recommended water bath temperature is 60°C. This minimizes evaporation from the bath, reduces the risk of burns, and minimizes the loss of heat energy into the lab environment. The bath temperature should be 20°C higher than the vapor pressure temperature of the solvent. In this example, a vacuum pressure is chosen to produce a vapor pressure temperature of 40°C.

(Calculating vacuum pressure will be discussed in the next section.) The condenser temperature should be 20°C lower than the vapor pressure temperature of the solvent. In this example, the vapor pressure temperature is 40°C so the condenser temperature should be 20°C.

To conserve water and maintain lower condenser temperatures, Lauda® Chillers may be used as an alternative cooling method over standard tap water methods. (Choosing an appropriate Chiller will be discussed in later sections.)

The above example illustrates the 20-40-60 Rule
