Using a micropipette in your laboratory. The adjustable micropipette is a Wisconsin invention developed through interactions among several people, primarily inventor Warren Gilson and Henry Lardy, a professor of biochemistry at the University of Wisconsin-Madison. Micropipette tips should not be touched even with gloves on to prevent contamination. Micropipettes are the type of air displacement pipettes that are used to transfer the small quantities of solutions measured in microliters, 1000 l (microliters) equals to 1 ml (milliliter) and is the maximum amount that is commonly dispensed with the micropipettes. Piston-driven air displacement pipettes are a type of micropipette, which are tools to handle volumes of liquid in the microliter scale. (Note that the bioink units could in principle be prepared to contain a hydrogel, in . Air Displacement Micropipette This type of micropipette works on the air displacement principle. Nomenclature. In this technique, the micropipette is extended to the surface of a cell, and a small negative pressure is applied to create a tight seal between the cell and the tip of the micropipette. What are the parts of a micropipette? Looking at Figure 3.1, you can see that each micropipette has a similar but different display window. The piston moves down, displacing a volume of air that corresponds to the selected aspirating volume of the liquid. This will attach the tip to the shaft. Micropipettes are utilized in the laboratory to transfer small quantities of liquid, usually down to 0.1 uL. In other words, for P1000, the maximum volume is 1000 L, so the first top digit is thousands of uL; for P200, the maximum volume is 200 L, so top digit is hundreds; and for P20, top digit is tens. A.
