Burette is a measure of a liquid's most accurate. Burette has a volume of 25 ml, 50 ml, and more. Burette used for titration process. Titration process is the addition of a reagent to the reagent that will cause a reaction. Burette has a scale like the ruler which can read up to two decimal places, for example 5.24 ml. To determine the last digit readings in Burette liquid that is a curved line that is inside the Burettete, there are two lines are above and below, read the scale on the Burettete with respect to the curved lines below. Burette usually used for liquids that have a low concentration, for example 0.1003 M.
The Burette shape is long like a pipeline of approximately 30 cm for Burette 25 ml and 60 cm for Burette 50 ml. There is a scale of 1 ml to 25 ml or 50 ml from top to bottom. Among a scale of 1 ml to 2 ml and so there are 10 scales which indicates 0.1 ml to 0.9 ml. Among a scale of 0.1 ml and 0.2 ml indicating the centerline of 0.05 ml. So we can read the Burette to 2 decimal places. At the end there is a small tap Burette like tap water. This faucet is used to open and close the Burette. At the time of the Burette open, fluid in the Burette going out or drip. When used in the process of titration, Burette position upheld straight. If Burette in a state tilted the volume of liquid coming out of the tap Burette will not be accurate and the titration process must be repeated. To enforce the Burette, plumb worn clamp embedded in the poles. Tip of the clamp with rubber so Burette will not be broken when clamped by the clamp.
To use the Burette, make sure the Burette is clean and has been washed. Rinse the inside Burette with distilled water 3 times and remove the distilled water through the taps. Before introducing the liquid into the Burette, rinse the inside of the Burette with liquid and remove liquid through the tap. This is done 3 times so that the liquid is put into the Burette is not reduced concentration because it is mixed with distilled water rinses the rest of the first. To insert fluid into the Burette, Burette taps cap and place a funnel at the top Burette fouled with blotting paper or tissue so that no air can come out of the Burette when the fluid entry.
Enter liquids with 100 ml beaker into the Burette through the funnel. Enter to exceed the scale of the Burette. Place a beaker containing the remainder of the fluid before it under the tap Burette. Open the tap Burette so that the liquid flows into a beaker. There must be no air bubbles on the top or bottom of the faucet tap. If all parts of the Burette was filled with liquid, then close the faucet Burette. Reinsert the existing liquid in a beaker of 100 ml under the tap Burette into the Burette through the funnel up over the scale of the Burette.
Lift the funnel and blotting paper, being careful not to blotting paper into the Burette. Note the liquid over the Burette scale and open the faucet slowly Burette so that the liquid drops. Close the faucet Burette if the liquid has reached a scale of 0.00 ml Burette. At the time of titration, at the base of a pillar or under the tap Burette, must be laid white tile or white paper so that the color change signaled the end of the titration process becomes clear.
Pipette have a level of accuracy under the Burette. Pipette used to measure fluid that Volumetric pipette and Graduated pipette. Volumetric pipette is small pipe and has a middle section oval tube as goiter. Volumetric pipette size assortment among which 1 ml, 2 ml, 5 ml, 10 ml, 20 ml, 25 ml, 50 ml and so on. Fluids are measured with the volumetric pipette is very accurate for example, if it took 5 ml of fluid with volumetric pipette 5 ml, the liquid coming out of the volumetric pipette exactly 5 ml. On top of the pipette Volumetric there is dark or blue line indicating the boundary volume pipette. Volumetric pipette tip taper so that the liquid that comes out easily in one direction.
Graduated pipette shaped like a straight pipe. Graduated pipette assortment of sizes among which 5 ml, 10 ml, 15 ml and others. The accuracy of a graduated pipette is lower when compared with the volumetric pipette. In the pipette there is a scale to 0.05 ml, for example, in graduate pipette 10 ml, there is a scale of 1 ml to 10 ml. Among a scale of 1 ml and 2 ml contained a scale of 0.1 ml to 0.9 ml. With a graduated pipette, the liquid can be measured up to 2 decimal places, for example 4.25 ml. This graduated pipette as Burette but do not have a tap at the bottom. Graduated pipette tip taper as volumetric pipette so that the liquid out easily in one direction.
How to use a pipette to take a liquid both for volumetric pipette and graduated pipette is the pipettes must be clean and have been washed and dried. If the pipette is not dry, then rinse the pipette with distilled water 3 times. And rinse with a liquid to be taken 3 times as well. This is done so that the liquid does not mix with distilled water and the concentration is reduced. After the Pipetteerballon plug at the top of the pipettes. Pipetteerballon made of rubber that is ball with three pipes. The first pipe at the top pipetteerballon to remove the air from the ball. In the pipeline there is a triangular arrow. The second pipe at the bottom like the letter t tiny of the pipetteerballon is used to draw air and suck fluids, other pipe serves to reduce the liquid. In each of the pipes there are arrows.
Attach a pipette on the bottom of pipetteerballon, enter into a pipe. And the exhaust air from the pipetteerballon by means of a ball is pressed together with the arrows on the pipe at the top of the pipetteerballon. So that the pipetteerballon will shrivel. Wipe the outside of the pipette from top to bottom using a tissue or blotting paper to dry, try do in one wipe. Open the lid of the bottle of liquid to be taken, then insert the pipette into it. Suction fluid by a squeeze of arrows on the pipe with a rubber ball that is inserted pipette.
The liquid will rise into the pipette and pipetteerballon balls will be filled with air. Take up liquid over the scale of the pipette. Then lift the pipette from the liquid and wipe the outside of the pipette from top to bottom using a tissue. Try doing in one wipe, so that pipette becomes dry. And there is no liquid from the outside pipette down and increase the volume of fluid. Place the pipette on the bottle neck where fluid before and tilt fluid bottle 45 ○ with left hand, if the right hand holding a pipette. Or vice versa.
Enforce pipettes, pipette along with Pipetteerballon hold with one hand, the index finger and thumb holding a sign triangular arrow on the pipetteerballon to reduce the liquid. Press the arrow so that the liquid down into the bottle neck. Eyes fixed on the movement of fluids, do not pass on a scale of 0.00 ml pipette. There are two curved lines inside the pipette, stop the decline of this fluid if the bottom has a curved line on a scale of 0.00 ml.
Take the pipette and still hold together with a pipetteerballon, while the hand holding the bottle neck enforce bottles and caps with a lid. For example the liquid to be taken is 5.55 ml. Take an empty 100 ml beaker with a hand that was holding the bottle and enforce the pipette. Tilt the beaker 45 ○ like the neck of the bottle. Lower fluid to 5.55 ml. The rest of the liquid in the pipette is inserted back into the bottle. Pipette which has been used should be washed again with water and then with soap and finally with water until clean. The most important part is cleaned inside the pipette. Do not dry in the oven for pipette, pipettewill expands, thereby reducing the accuracy of the pipette.
In the lab The fluid is of various kinds, there are acids, bases, salts, distilled water. Each type of liquid has the properties of each are different. The tools used to measure the fluid is made of glass that is resistant to all the properties of a liquid. There are various kinds of glass measuring tools, starting from the accurate to the technical. Measurement tools among which the burette, volumetric pipette, and graduated pipettes.
