A laboratory rubber apparatus is used in all different types of experiments and its main purpose is for moving air or liquids. It does this by suction.

There are many other different types of equipment or apparatus that are commonly used in laboratories and experiments, but the specific equipment found can vary depending on the scientific subject and the experiment being conducted.

Below are a few examples of the most common types of laboratory equipment:

• Burette - this is most commonly used in titrations to measure precisely how much liquid is used because an incorrect measurement of liquid can disrupt the whole titration.

• Pipette - this is used for moving small amounts of liquid from one location to another. They can be made of glass or plastic if they need to be disposed of.

• Bunsen burner - these create flames to heat up substances during experiments. The flame can be adjusted from a yellow flame (a "cooler" flame) to the blue flame ("hotter" flame).

• Tripod - a tripod is a three legged metal stand that supports flasks, beakers etc. Whilst they are being heated by a Bunsen burner underneath.

• Microscope - these are most commonly found in Biology laboratories. They are used for examining objects that are too small to be seen with the naked eye.

• Crucible - these are used to heat up small amounts of solid substances to extremely high temperatures by being placed over a Bunsen burner on a blue flame.

• Test tube rack - a basic piece of laboratory equipment. Used to hold test tubes whilst they are not being used or after they have been used. Useful for comparing reactions i.e. For color changes.

• Tongs - useful for picking up items such as test tubes or flasks after they have been heated over the Bunsen burner. They can also be used to hold test tubes over the flame.

These are just a few common pieces of laboratory equipment. For a more complete list, use the following link: http://www.scribd.com/doc/57465131/Laboratory-Apparatus.
