A laboratory is an important place in science. It can be used to carry out experiments, observe animals, test materials or carry out chemical analysis. A laboratory generally contains equipment and apparatus required for the experiments to be carried out. A laboratory can be used for secondary school science, university science, or commercial purposes. A factory or industrial plant that manufactures products may also have a laboratory to test the quality of materials or research new products. Below is a list of essential equipment used in laboratories.
The laboratory is the heart of scientific research, and without the equipment and technology used there, the world would be a much different place. The major equipment and technology used in laboratories today can be divided into six categories:
- safety equipment
All scientists need to wear safety equipment to protect themselves from dangerous circumstances. The type of safety equipment used in scientific laboratories depends on the type of research being done. For example, suppose the scientist is working in an area where there are noxious chemicals in the air. In that case, the safety equipment may include a respirator mask that is made from a material that filters out toxic fumes and vapors.
- electronic instruments
Advances in electronics and instrumentation make it possible to do experiments that were once impossible and do them faster and better than before. For example, scientists have recently created an artificial cell that can sense and transmit information about its environment in a way that is similar to how real cells do it. The artificial cell is made up of living and nonliving components.
The living components include a membrane made by mixing cell membranes from two different organisms. The nonliving components include a microprocessor that receives signals from the membrane and then transmits those signals to other microprocessors that perform various tests on the samples of water that have been placed in the artificial cell.
The most important tool in any lab is the researcher, but you can get by on physical equipment, too. Here is a list of the most common tools used in research labs: You will notice that many of the tools listed are related to the safety of the lab worker. This is because working in a lab can be dangerous if proper safety precautions are not taken. Occasionally, the most important tool in a lab can also be the most dangerous one – the scientist.
As the name implies, apparatus is the device and tools you need to perform experiments in a laboratory. The proper equipment for a particular experiment is dependent on its specific requirements. This includes the source of energy (if any), the kind of gases to be used, and the choice of a suitable container to hold the material to be heated. You’ll need a different apparatus for a gas experiment than for an experiment that involves melting and/or evaporating a solid. Most apparatus is designed to hold a particular object, such as a beaker or a test tube. For example, an apparatus used to measure the velocity of a gas stream would include a tube connected to a gas source.
- measuring equipment
In science labs, the most common equipment will be scales to measure mass, balances to measure weight and length, and thermometers to measure temperature. Others include ultraviolet (UV) lights to measure UV radiation, spectrometers to measure light, refractometers to measure the density of a liquid, pH meters to measure the acidity of a solution, balances to measure the amount of a substance (such as soil), and a variety of other instruments.
In a chemistry lab, other equipment may include burners and fume hoods to help with experiments; glassware such as beakers, Erlenmeyer flasks, test tubes, and Petri dishes; distilling equipment such as retorts and condensers; acid-base indicators such as litmus paper.
- library resources
Libraries are the Internet of the past. They’re places where you go to get interesting information that you can’t find elsewhere. It’s true: If you’re looking for a book, and the library doesn’t have it, it doesn’t exist. Libraries of all kinds—school, public, and university—are packed with books, magazines, newspapers, and DVDs that can be checked out for free forever.
The library is a valuable resource for students, teachers, researchers, and anyone who is just curious.
The essential piece of equipment in a laboratory is the fume hood, which prevents the spread of hazardous chemicals. Some other important equipment includes a beaker, a Bunsen burner, and laboratory glass, which is still used today. The Bunsen burner is a source of heat that is used to keep samples at a certain temperature. It can also be used to burn off gasses that form when chemicals are mixed. There are two types of Bunsen burners: a gas burner and an electric burner. The beaker is a long and thin glass container that can be sealed. This allows chemicals to be mixed without exposing the container to the air.
