A laboratory is a place where varied types of scientific research and experiments are performed. A laboratory is used for observation and testing. The laboratory is found in schools, colleges, health centers, hospitals, research centers, investigation centers etc. This can be just a single room or a complete building equipped with all facilities to perform experiments. The laboratories are designed in such a way that depending on the subject of research, varied tasks can be performed like scientific experimentation or research, manufacturing of drugs and chemicals, collection of data and samples etc.
The science subject as a whole is a vast subject consisting of various fields of studies, though the main categories are physics, biology, chemistry and medical where there is the maximum need for a laboratory and laboratory equipments. Its a common fact that the basic requirement in a laboratory is the laboratory apparatus and equipment. No experiments can be performed or no studies can be done in a laboratory without using these apparatus. The lab apparatuses are used during the experimentation process to collect data, to hold samples, to heat or mix solutions, to measure, and various other such tasks.
Depending on the subject and the experiment, the laboratory apparatus can be classified as physics laboratory, biology laboratory, chemistry laboratory, medical lab apparatus etc. There are a large number of apparatus which are used in every laboratory for each categories. When we talk about these apparatus, we imply lab tools, equipments and support systems that help the user, be it the researcher or the scholar to perform different experiments.
There are certain laboratory apparatus, designed specific to subjects. Like for instance, the popular physics lab equipments are Ammeter, Voltmeter, Rheostat, Galvanometer etc. Similarly, for Chemistry, the most widely used lab equipments are Alcohol Lamps, Evaporating Dish, Centrifuge, Calorimeter, Filter Paper etc. The hospital or medical laboratory apparatus are altogether different like as there are histology lab equipments, blood bank equipments, tissue culture equipments for medical related experiments. However, there are certain common lab apparatus which are invariably required in every type of experiments in a laboratory like a microscope, balance, beaker, flask, petri dish, safety equipments, tripod stands, test tube, etc. Besides these, a laboratory also consists of filtration equipments, cooling apparatus, lab consumables, mixing equipment, heating equipments and so on.
