 Analytical chemistry is a branch of chemistry in which we perform various analysis and quantification of different chemical compounds. For the quantifications, we need different lab equipment. These are wing balance, different classwares, micropipers, and manual pipers. Now, we will discuss them briefly. Wing balance is an instrument that is used to measure the mass. They are of two types, analytical balance and precision balance. Both of them can be different as per quantity and precision. If we can see this wing balance, it has three different windows, the upper window and two side windows. This is the control panel of the wing balance through which we can select our parameters. If we can see the monitor of wing balance, it can measure up to 0.0001 milligram of the weight. This is called analytical balance. Coming towards the classwares, the first class equipment we have is beaker. Beaker is considered to be a workhorse lab equipment of any laboratory. It came in different sizes. If we can look at the shape of the beaker, it has flat bottom and wide mouth. It has the various volume capacity. This beaker can measure the volume up to 250 ml. But, measurement of the volume through beaker is not considered to be very precise because there are chances of 5% of instrumental error. Coming towards the uses of the beaker, we use the beaker for storing of the solution, mixing of the solution and sometimes heating of the solution due to its flat bottom. The next class where we have is conical flask. Conical flask is also known as Erlenmeier flask. It can be seen, it has the flat bottom and narrow neck. It can be used for transferring of the solution and gently shaking of the solution when you have to mix the solution. It also came into the various volume capacity. When we need any solution to be covered, we can pack, we can cover its mouth with paraffin film and cotton. The next class where we have graduated slender. The graduated slender is used for measurement of the liquids with up to 1% of the instrumental error. It is considered to be precise for measurement of the volume of any liquid. Precise then beaker and conical flask. The next class where we have is volumetric flask. Volumetric flask is used for the preparation of the solution. It came with the fixed volume capacity. Like this volumetric flask have a capacity of 500 ml. It can came with the topper cap. This plastic instrument is called manual pipert. Manual pipert is used for the transfer of liquid volume in smaller quantity. With this manual pipert we can transfer the volume of liquid up to 25 ml. This plastic part of the manual pipert is called pipert filler that can be fitted on its upper surface. It has two parts. This small wheel that can be a rotatable and a button. Small wheel is utilized to aspirate the liquid volume into the pipert. As if I put that pipert into the liquid and rotate the wheel with my thumb you can see the liquid start aspirating into the pipert. And with the pressing of this button will release the liquid or dispense the liquid out of the pipert. Manual pipert also came into different volume capacity. This one was having the capacity of 25 ml. And the next one is having the capacity of 10 ml. The next lab equipment we have is micropipert. If we want to measure the volume of liquid into the microliters so we use the micropipert. It also came into various volume capacity like this micropipert can measure the volume from 100 microliters to 1000 microliters. There are various parts of the micropipert. That circular part of micropipert is known as plunger. Plunger performs two functions. The first function is the adjust the volume of micropipert by rotating it clockwise and anticlockwise. The second function of the plunger is to aspirate and dispense the liquid from the micropipert by pressing it downward. The next part of the micropipert is tip ejector. Tip ejector is can remove the tip. If I can show you like this is the micropipert tip, we put the tip on tip cone of the micropipert. With that plunger we can aspirate the liquid into the micropipert. By pushing it down we can dispense the liquid out of the micropipert. And with that tip ejector with my thumb I can remove the micropipert tip very easily. Usually the micropipers are utilized in the research of biological sciences because we have to provide a sterilized condition while transferring of the pollution. As we have seen the micropipert tip can be changed easily to that insure to provide a sterilized environment.
