The JoVE video player is compatible with HTML5 and Adobe Flash. Another common use for serological pipettes is the careful layering of reagents for the creation of density gradients like a ficoll gradient, which is used to purify cells from blood plasma. Pipette and pipet describe completely different liquid handling devices—for example, pipette is used for the device that you use pipette tips with, whereas a pipet describes the glass (or plastic) tubes used for serology (serological pipet) and chemistry (volumetric pipet). A Serological pipette is a graduated pipette in which the calibration marks extend all the way to the tip. Be careful to use gentle pressure when aspirating liquids, particularly when using smaller volume serological pipettes to avoid contaminating the filter and sample or damaging the pipet-aid. Mohr pipettes: Have hash marks always end before the tip. Comparison to Standard Deviation. The same pipette dispenser can be used with a variety of serological pipette sizes, depending on the amount of volume you wish to transfer.
