A device for grinding substances into smaller particles, or for grinding and mixing solids together. To use, place the substance in the mortar and press or grind it with the pestle until it is fine or uniform; do not pound, as that can crack the mortar. The surface of the pestle and the inside of the mortar are roughened to increase friction during grinding.
A petri dish is used for culturing micro-organisms or plant tissue. Made of glass or plastic, it has the form of a cylindrical dish. The dish can be reused after being sterilised beforehand, either in an autoclave or by heating in an oven at 160 °C.
A glass stirring rod, used to stir solutions; one end is paddle-shaped and is used to stir substances until uniform. It also helps when pouring a solution into another vessel: pouring the solution so that it runs down the stirring rod gives much better control over the direction of flow.
