A beaker is an open glass cylinder with a pouring lip used as a standard laboratory container. It is a simple container used for mixing, stirring, and heating liquid. A reagent bottle can be used for storing and mixing chemicals, mixing, and display. A Bunsen burner is a small laboratory burner consisting of a vertical metal tube connected to a gas source. It produces a very hot flame from a mixture of gas and air that passes in through the adjustable holes at the base. A burette is a graduated glass tube with a stop clock at the bottom used especially in laboratory procedures for accurate fluid dispensing and measurement. An Erlenmeyer flask is used to heat and store liquids. Its bottom part is wider than the top. This will make the content heat up quicker because of the greater surface area exposed to heat. An evaporating dish is used to heat and evaporate liquids. A Florence flask is used for heating substances that need to be heated evenly. The bulb-shaped bottom allows the heat to distribute through the liquid more evenly. The Florence flask is mostly used in distillation experiments. A funnel is a piece of equipment that is used in the laboratory to transfer liquids into another container so they will not spill. A micro spatula, commonly called a spatula, is used to transfer small amounts of solid from one container to another. A pipette is used for moving small amounts of liquids from one container to another. It is usually made of plastic and is disposable. A pair of mortar and pestle are used to grind solids into powders for experiments. Ring stands are used to support items being heated. Clamps or rings can be used so that other items may be placed above them for heating using a Bunsen burner. A test tube holder is used to hold test tubes while being heated. A test tube rack is used to hold test tubes upright while observing reactions or when test tubes are not used in experiments. A thermometer is used to measure the temperature of solids, liquids, and gases. They are usually in centigrade but can also be in Fahrenheit or Kelvin. Tongs are used to hold different objects, such as flasks, crucibles, and evaporating dishes, when they are hot. A volumetric flask is used to make solutions of fixed volume. It is solely used in preparing chemical solutions.
