In this study, we have tried to assemble small parts by using micro manipulator. In this case, it is necessity to inject binding material at narrow area (from 10μm to 0.1μm). This report discusses a pipetting device that can inject small quantities (from sub-pico liter to femt litter range) of binding material. Because the size of the micro pipette used to dispense is minute, the surface tension of the adhesive and the influence of the viscosity are very greatly related. Then we develop the pipetting device using the force of gravity by free fall, and experiment the performance of pipettes with different point angle. From experimental result, we obtain the relation between the point angle of pipette and the quantities of binding material.
