INTRODUCTION
Separatory funnels are used in laboratories primarily for liquid extractions, and are intended to
facilitate the separation of two immiscible liquids of different densities into separate layers. Some
funnels are used to add reagent solution into a reaction vessel.They are, therefore, often provided with
