Chemistry Laboratory Apparatus And Their Uses With Pictures Pdf
Chemistry is an important subject as it is the study of matter, its properties, composition, and reactions. In order to study these aspects, chemistry laboratories require a set of specialized equipment known as laboratory apparatus. These apparatuses are used for various purposes such as measuring, analyzing, heating, and mixing different substances. In this article, we will discuss some of the most commonly used apparatuses in chemistry laboratories along with their uses.
Beaker
A beaker is a cylindrical container made up of glass or plastic. It is used to mix, heat, and measure the volume of liquids. Beakers are available in different sizes ranging from a few milliliters to several liters.
Burette
Burette is a long and narrow glass tube with a tap at the bottom. It is used to deliver a known volume of liquid accurately. Burettes are used in titrations to measure the volume of the solution added.
Pipette
A pipette is a narrow glass tube used to transfer a small volume of liquid from one container to another. It is used to dispense an accurate volume of liquid. Pipettes are available in various sizes ranging from a few microliters to several milliliters.
Volumetric Flask
A volumetric flask is a glass container used to measure and mix solutions with a high level of accuracy. The flask has a long neck with a flat bottom and a precise volume marking. The marking indicates the accurate volume of the solution that the flask can hold.
Test Tube
A test tube is a small cylindrical container made up of glass or plastic. It is used to hold, mix, and heat small amounts of chemicals. Test tubes are available in different sizes ranging from a few milliliters to a few hundred milliliters.
Bunsen Burner
A Bunsen burner is a gas burner used for heating liquids, solids, or gases. It has an adjustable flame that can be controlled by adjusting the air and gas supply. The flame can be adjusted to produce a hot blue flame or a cooler yellow flame depending on the requirements.
Fume Hood
A fume hood is an enclosed space used to conduct experiments that produce harmful gases or vapors. It has a ventilation system that removes the harmful gases and vapors from the experiment area. Fume hoods are essential in laboratories to ensure the safety of the workers.
Graduated Cylinder
A graduated cylinder is a tall narrow container with a precise volume marking. It is used to measure the volume of liquids with a high level of accuracy. Graduated cylinders are available in different sizes ranging from a few milliliters to several liters.
Hot Plate
A hot plate is an electrical device used to heat solutions. It has a flat surface on which a container can be placed. The surface heats up and transfers the heat to the container, resulting in the heating of the solution.
Microscope
A microscope is an instrument used to observe small objects that cannot be seen with the naked eye. It has a series of lenses that magnify the object and produce an image. Microscopes are used in various fields such as biology, chemistry, and medical sciences.
Conclusion
Chemistry laboratory apparatuses are an essential part of any laboratory. They are used for various purposes such as measuring, heating, and analyzing different substances. In this article, we have discussed some of the most commonly used apparatuses in chemistry laboratories along with their uses. It is important to understand their functions and use them correctly for accurate results and the safety of the workers.
