Several types of equipment are required for any functional laboratory to operate appropriately. Be it a school, research, or a medical laboratory; special apparatus are needed. So, what are some of the common lab equipment names and their functions?
Laboratory apparatus is used to carry out scientific experiments, and they range from simple to complex depending on the uses. While different types of laboratories need different types of apparatus, some are common for all.
Laboratory equipment refers to various gear used in a laboratory to perform different tasks. These tools are meant for use by scientists, pupils, teachers, and even medics. For example, some science lab apparatus are used for weighing objects, mixing and preparing solutions, and others for cleaning vessels.
While performing any experiment, you need to be careful to avoid getting hurt. To ensure safety and adequately carry out an experiment, it is essential to know the names of lab equipment and their uses.

Lab apparatus are categorized into various classes depending on their uses. Below are all the categories of lab equipment and their names
How many types of computer do you know?
Have a look at these common lab equipment names and images and their various functions/uses in the lab.
A microscope is a popular lab apparatus used to observe things that are too tiny to be observed by the naked human eye. There are many different types of microscopes.
A light microscope uses lights and a series of magnifying lenses to observe a tiny specimen. On the other hand, an electron microscope uses a beam of electrons to form a magnified image and, thus, is more powerful.
This is a common type of lab vessel used to hold and mix liquid substances. A test tube is finger-like and open on one end. Test tubes come in many different sizes, but the standard size is 18 x 150 mm.

A watch glass is a popular type of chemistry lab instrument. It's a concave piece of glass customarily used to hold solids, evaporate liquids, and heat small quantities of a substance.
This apparatus is a small receptacle usually made using porcelain. Not all laboratory glassware is appropriate for heating as some can get damaged or break.
However, a crucible is heat-resistant and is ideal for containing compounds when heated to high temperatures. In addition, it has a lid that is meant to contain particles of smoke.
Volumetric flasks are another popular chemistry laboratory equipment. It is a type of glassware calibrated to hold exact volumes of a liquid at a precise temperature. In chemistry, it is used to prepare standard solutions and for accurate dilutions.
There are different sizes of this flask, and the volume is usually indicated. Depending on what amount of solution you want to prepare, you can use a 50ml, 125ml, 250ml, 500ml, or 1000ml volumetric flask.

Just like test tubes, beakers are used to store, heat, or mix substances. Beakers are cylindrical with a flat base, have a spout, and do not have rounded bottoms. They also come in a variety of sizes.
It is used for sterilizing objects and heating. The gas used could be natural gas or liquified petroleum gas like methane.
This type of laboratory apparatus resembles the kitchen spatula, just that it is much smaller. Spatulas are small hand-held tools used to scoop and transfer solids. They can also be used to apply paste-like treatments.
Most spatulas are resistant to acids and heat, making them suitable for use with a range of substances.
This common laboratory apparatus produces a magnified image of an object. It's basically a convex lens in a frame with a handle.
It is also referred to as a newton meter. The scale is used to measure the weight of an object by the tension of a spring. It consists of spring on one side and a hook on the other.

It works by the principle of Hooke's law, which states that the force applied to an elastic object is directly proportional to the extension provided the elastic limit is not reached. This force gauge only measures weight and not mass.
A dropper, also called a Pasteur pipette, is a short glass or plastic pipe with rubber on one side. It is used to deliver small amounts of liquids a single drop at a time.
This common type of laboratories apparatus is used to measure the volume of a liquid. It is graduated, and every marking shows the amount of a reagent. Just as the name suggests, this glassware is cylindrical and is also narrow.
We all have come across thermometers as we frequently use them at home. Thermometers used in laboratories are almost similar as they also measure the temperature of substances (not body temperature) and have a high degree of precision.
The basic info about the microscopes everyone should know about
This simple piece of chemistry laboratory apparatus is used to deliver known volumes of a substance. It is often used during titrations. It is a long graduated tube with a stopcock on at the lower end. The most popular burettes are the 50ml, 25 ml, and 10ml varieties.
Solids are often weighed before use, as some experiments require exact amounts of substances. A balance is used to weigh objects. Analytical and toploading balances are the most commonly used types.
Funnels are yet another essential kind of apparatus. They are used to deliver substances into vessels with small openings. There are several types, each with a different function, such as filter, thistle, and dropping funnels. Büchner and Hirsch's funnels are good examples of organic chemistry laboratory apparatus.
A wash bottle is a squeeze container with an extended nozzle. It is used to rinse glassware and for sterilization. Wash bottles are mostly made out of polyethylene. Depending on the task you wish to perform, you can fill it with another solvent, for example, ethanol or deionized water.
Incredible types of farm machinery you need to know
When working in a laboratory, you often have to deal with chemicals, heat, and other hazardous substances. Tongs are used to grasp harmful objects and also hold hot vessels. Each type of tongs is designed for a particular use. Typical examples are beaker, utility, and crucible tongs.
You will not miss this equipment in any physics lab. An ammeter is used to measure the amount of current in a circuit. The SI unit of current is Amperes (A).
Our laboratory apparatus list cannot be complete without mentioning a tool used for cleaning. Brushes for test tubes are used to clean containers such as flasks, beakers, and test tubes. After use, an apparatus should always be cleaned and safely put away.
A balance or scale is an instrument used to measure mass in the science laboratory. Types of balances are triple beam balance or electronic balance.

Various types of equipment can be used to measure volumes of different liquids. Such equipment are Erlenmeyer flasks, Florence flasks, graduated cylinders, beakers, volumetric flasks, burettes and pipettes.
This article contains some of the most common lab equipment names. Most of these names may not be new to you. However, you need to understand their uses to avoid using apparatus for the purpose they are not supposed to be used for.

Legit.ng also published an article on the properties of water. Up to 60% of the human adult body is made up of H2O, and it plays crucial roles in the bodies of living things, such as food movement, skin hydration, and much more.
Pure water is colourless, odourless, and tasteless. But, like any other chemical substance, it has unique properties that distinguish it from the rest.
