What is the lightest possible thing that you can think of weighing? Well here’s a device that can even measure the weight of the air we breathe.
What is a microbalance?
The microbalance is a device that is used to measure weights that are as light as a millionth of a gram. Hence, it can be used to measure the weight of aerosol particles too. This is extremely sensitive, compared to the analytical balance we have used in our school chemistry labs, that reads up to the sub-milligram range. Needless to say, this device must be very sensitive to be able to measure such small quantities with
Thermal analysis, as the name suggests is analyzing the change in the properties of materials when they are subjected to different temperatures. Different techniques are used and the response of the material is then plotted as a function of temperature and time. This is an indispensable branch of materials science. It is crucial to determine the way a substance reacts to a change in
Over the years, microscopes have evolved from being magnifying glasses (then also called ‘flea glasses’ as they were mostly used to look at tiny bugs) to becoming complex equipment with adjustable powers. Today, they are one of the most commonly used apparatus in laboratories.
Where can they be used?
They are used to view anything from samples of minerals to cells of the human body: anything that is too small to be seen by the naked eye but must be observed for the purpose of scientific research or for
