Continuous still set

There are two main types of solvent still that are commonly employed in organic research laboratories. One is the classical distillation set-up consisting of distillation pot, still-head, thermometer, condenser, receiver-adaptor, and collection vessel. This arrangement is described in more detail in Chapter 11, and is used for the distillation of solvents that are either required infrequently, or that can be stored without deterioration for long periods of time. The other is a continuous still set-up that consists of a distillation pot, collecting head, and condenser (see Fig. 5.1). 

However, the synthesis of Medicinal Compounds usually makes use of a continuous still set-up which is essentially comprised of a distillation vessel, collecting head, and a condenser as shown in Fig. 3.1. 

The continuous still set-up is designed in such a manner that the distilling solvent gets condensed and collected in a collecting head,...
