Agar preparation

Agar is a substance made largely of polysaccharides obtained from some species of algae such as Gelidium.

In the laboratory, agar is usually in powder forms, and preparation is done according to manufacturers' instructions depending on the type of agar.

For example, nutrient agar is a multipurpose medium for culturing bacteria. It is prepared by first dissolving a weighed amount into a measured volume of water. The solution is then stirred and autoclaved.

After autoclaving, the molten agar is allowed to cool a bit before being dispensed into culture plates.
