There is a lot of equipment used when experimenting with chemistry and these pieces of equipment have a variety of uses depending on what you are investigating. Some items include Bunsen burners, thermometers, infrared thermometers, pH meters, test tubes, pipettes and centrifuges.

• Bunsen burners: This piece of equipment is widely used in the areas of biological and chemical science. It is primarily used to heat up water and sterilize things. It was created by Robert Bunsen, who got a patent for the device back in 1856. It creates a single flame by using gas and the intensity of this flame can be changed by altering the amount of air that is taken in at the bottom.

• pH meters: The pH meter is used by chemists to assess the acidity or alkalinity of a liquid. These readings are retrieved through a glass electrode on the end of a measuring probe. This measurement is then shown electronically on the screen display. This is seen as a much more advanced way to measure acidity and alkalinity and another way of doing this is pH paper. However, this is deemed to be not as accurate as the pH meters.

• Centrifuges: Centrifuges are machines that possess the ability to separate materials of different densities. This is achieved by spinning them around horizontally in a tube within the machine. This separates the materials by moving the denser substances through the length of the tube and moving the lighter materials to the opposite end.

• Infrared thermometers: These devices are able to measure the temperature of varying objects other than water. They are different from most thermometers as they can gather a temperature reading without having to come in contact with the object it is measuring. Infrared thermometers are ideal for quick measures of an object's temperature.
