The primary function of a stirring rod is to stir solutions by hand. Stirring rods have other uses in the laboratory, however, including helping to decant liquid from containers, breaking up emulsions and inducing crystallization.Know More
Stirring rods are used to decant or pour liquids slowly. Slow pouring is essential when working with potentially hazardous chemicals that can react too quickly. Using the stir rod to decant liquid makes it easier to keep a precipitate in the bottom of the beaker, because the liquid pours more slowly, reducing the chances of it agitating the solid.
To induce crystallization in a recrystallization experiment, the glass stirring rod is scraped against the inside of the flask containing the solution.Learn more about Chemistry

The primary function of the clitellum is to create a cocoon for the developing young of the annelids that possess them. The most well-known species which have a clitellum are earthworms and leeches, on which the clitellum appears as a pale saddle-like structure a few segments down from their mouths. While mating, the worms build the cocoon around them, leaving the fertilizing gametes behind as they withdraw and seal it.Full Answer >
