There are Pasteur Pipettes offered by us that are standard piece of laboratory equipment consisting of a thin glass or plastic tube, usually topped by a rubber bulb. It is a liquid transfer instrument that does not have the objective of its quantification. They are cotton-plugged, glass tube drawn out to a fine tip, used for the sterile transfer of small volumes of fluid. They are used to measure a volume of solution extremely precisely. It can be used for the purification of liquids, placing in the pipettes materials, such as glass wool, activated carbon, etc. The Pasteur Pipettes are very efficient.
