A Pasteur pipette is basically an eye dropper. It is used to collect liquids, to be utilized for different purposes.
To properly calibrate a pipette for accurate measurements in the laboratory, follow these steps: Check the pipette for any visible damage or contamination. Use a calibrated balance to weigh the water dispensed by the pipette. Compare the measured weight to the expected weight based on the pipette's specifications. Adjust the pipette if there is a discrepancy by following the manufacturer's instructions for calibration. Repeat the calibration process until the pipette consistently delivers accurate measurements.
A pipette bulb is the rounded part of a pipette which you squeeze the air out of, then release to draw liquid into the pipette. If you are using a calibrated glass pipette, it will be a separate piece made of rubber which is fitted to the pipette. If it is a simple plastic pipette then the bulb will be made of the same semi-transparent plastic, and the pipette will all be one piece.
To calibrate a pipette for accurate measurements, follow these steps: Check the pipette for any visible damage or contamination. Set the pipette to the desired volume. Use a calibrated balance to weigh the water dispensed by the pipette. Compare the measured weight to the expected weight for the volume dispensed. Adjust the pipette as needed to ensure accurate measurements. Repeat the calibration process regularly to maintain accuracy.
To properly use a pipette in the laboratory to transfer liquids, first select the appropriate pipette size for the volume needed. Then, attach a disposable tip to the pipette. Press the plunger to the first stop to draw liquid into the pipette, and then release it slowly to dispense the liquid. Be sure to hold the pipette vertically to ensure accurate measurements. Dispose of the tip after each use to prevent contamination.
A pipette bulb or pipette filler should be used to safely draw and dispense liquids with a pipette. This device helps prevent exposure to hazardous chemicals and helps control the flow of liquids with accuracy.
Another name for Pasteur pipette is transfer pipette.

In the related links box below I posted the wikipedia article on pasteur pipettes. It has pictures and is well explained.
To properly use a pasteur pipette for accurate and precise liquid transfer in the laboratory, first, ensure the pipette is clean and dry. Next, draw the liquid into the pipette by gently squeezing the bulb and placing the tip into the liquid. Release the bulb slowly to draw in the desired amount of liquid. To dispense the liquid, hold the pipette at a slight angle and gently press the bulb to release the liquid drop by drop. Be careful not to introduce air bubbles, and always handle the pipette with care to avoid spills or contamination.
The purpose of a dropper pipette is to administer only a small drop of a liquid to something. The dropper pipette is a tool that will allow you to squeeze a single drop of the liquid it contains.

it is used to measure specific ammounts of solution

If a pipette has graduations marked on it, it implies that it is a multi-volume pipette. A fixed pipette only uses one volume all the time, and has no need for graduations. Not to say that someone couldn't mark graduations on a fixed volume pipette, in order to be overly thorough.
The apparatus used for dropping solvent onto filter paper is called a dropping pipette or a Pasteur pipette. It allows for controlled and precise dispensing of liquid onto a surface.
