Pasteur Pipette

Pasteur pipettes or droppers are used to transfer small quantities of liquids. They are usually made of glass tubes tapered to a narrow point, and fitted with a rubber bulb. Plastic Pasteur pipettes (or transfer pipettes) have their stems and bulbs in the form of a single piece made of plastic. It is not recommended to use Pasteur pipettes for work involving accuracy since Pasteur pipettes are not designed to measure specific volume; however, it can be used to add drops of reagents. To increase accuracy, the pipette is to be rinsed with the reagent. Generally, Pasteur pipettes are cheap enough to be disposable, however, so long as the glass point is not chipped, the Pasteur pipette may be washed and reused indefinitely. To use the Pasteur pipette, squeeze the bulb to expel air out of the pipette and submerge the tip of the pipette to the solution. Gently relax the bulb to draw the solution up making sure that the solution does go into the bulb, contaminating it. To dispense the solution, hold the tip against the side of the target container at a 30 to 45 degrees angle and gently squeeze the bulb. Sterile or non-sterile. Disposable. Sterile – individually wrapped, 100 pcs per polybag. Non-Sterile – bulk, 250 pcs per polybag. Capacity: 1 ml, 3ml, 5ml.
How to use Pasteur pipette: Pasteur pipettes or droppers are excellent for transferring small volumes of non-volatile liquids such as aqueous solutions. However, most organic solvents have a significant vapor pressure at room temperature. Affix a bulb to the top. Insert the bulb no deeper than the top segment of the pipet. Squeeze the bulb and then insert the tip of the pipet into the liquid you wish to transfer. Be sure to hold the pipet in an upright position. Gently release the bulb to draw the liquid into the pipet.
