normally utilized inside the laboratory for transferring a handful of milliliters of liquid to as much as 100 mL in quantity by way of a serological pipettor. Serological pipettes can be employed for mixing chemical methods, mixing mobile suspension, transferring liquids, and accurate measurements of liquid. Conveniently, all serological pipettors will in shape into any serological pipettor and permit for quick volumetric measurements.
usually, this kind of pipette is taken into account affordable enough to become disposable. on the other hand, providing the glass place is not really chipped, the Pasteur pipette can be click here washed and reused indefinitely. The volumes are generally marked within the stem, although the markings are certainly not significantly accurate.
