Hello everyone. Today I am going to show you some basic laboratory equipment as we use different apparatus in chemistry to perform chemical analysis. It beaker, conical flask which is also called as Arlin mayer flask, measuring cylinder, durates, pipette, glass rod, test tubes and retort stand. So let's start. The first one here you can see it's a beaker. The beaker it's made up of glass, it's parallel on two sides, it's made up of ordinary glass or it is also made up of borosilicate glass. Here you can see it's a measure of 250 milliliters but we get a beakers of the range 100 ml as well as 50 ml. Now here this one is called as conical flask. It is also called as Arlin mayer flask. Conical flask, it is also called as Arlin mayer flask. Now conical flask is used in titrations to carry out reactions. Now due to their shape, conical shape these flasks are efficient in containing splashing of chemicals while we are swirling. These flasks also come in different sizes 50 ml, 100 ml or here you can see it's 250 ml. This is measuring cylinder, they are graduated cylinder, glass cylinders, they are used for accurate measurement of liquids. They come in measures ranging from 5 ml to 100 ml. This one here is 100 ml graduated cylinder. You can see 100 ml, 90 ml, 80 ml. These are all marking, exact markings. Here this is a plastic one but usually we use glass glass ones. This is a pipette, it is here it is a 5 ml pipette. These pipettes are also graduated pipettes. Even though we are having measuring cylinders, we use pipettes, these pipettes are used for more accurate measurement of liquids. They are available in measure of 5 ml, 10 ml, 20 ml, 25 ml so on. Here it is a graduated pipette. Otherwise without graduation also we get pipettes. Now this is a suction bulb. Also it is used for sucking out the liquid. Next you can see this is a burit. This burit is a long cylinder graduated cylinder tube. One end is open and the other end is here has got a thin nozzle. There is a stopper to open the outlet to allow the liquid to flow out. Other burits may have pinch cock for releasing the liquid. Burits are graduated, here it is a 50 ml burit. We also get a burit of 25 ml capacity. These are called test tubes. They are used to carry out simple reactions. These small mouth test tubes, they will come at a measure of 5 to 10 ml. These are ordinary glass test tubes. Where reactions include high heating or high boiling is required, we get boiling test tubes which are used for stronger heating. This is a glass rod. One end is flat and the other end you can see it is like a nail. This is used for dropping indicators or for swirling, stirring the mixtures. These are called as glass rods. This is called reagent bottle. reagent bottle are glass bottles. Completely they are made up of glass. Even the cock is made up of glass to keep the moisture within the bottle and not allow the flow of heat or moisture from the bottle. Usually in the measure of 250 ml.
