摘要:
A micropipette is provided including at least one substrate, an inlet port through which a sample is delivered from the outside, a cavity to be poured and filled with the sample, an introduction hole, and an injection port for expelling the sample are formed on the at least one substrate. The substrate for forming the cavity is made of ceramics, a piezoelectric/electrostrictive element is provided for at least one wall surface of the substrate, and the sample moves as a laminar flow in the cavity. The volume of the cavity is changed by driving the piezoelectric/electrostrictive element to expell a certain amount of the sample in the cavity from the injection port. According to the micropipette, it is possible to form microspots with high accuracy and high speed. According to a dispenser including the micropipette, it is possible to efficiently dispense hundreds to ten thousands of different samples at one time and form microspots. Therefore, productivity is remarkably improved.
