Abstract:
1. A capillary polishing method of polishing a tip of a capillary for microinjection, the method comprising: first-polishing a first side of the tip by placing the tip on a polishing plate at a predetermined angle, pressing the tip against the polishing plate by a predetermined amount, and repeatedly moving the polishing plate at a predetermined speed by a predetermined distance with a pressured gas supplied to pass through the capillary such that the pressured gas comes out of the tip, the polishing plate having a surface roughened by dry etching; rotating the capillary around an axis thereof to determine a second side of the tip; and second-polishing the second side by placing the tip on the polishing plate at a predetermined angle, pressing the tip against the polishing plate by a predetermined amount, and repeatedly moving the polishing plate at a predetermined speed by a predetermined distance with a pressured gas supplied to pass through the capillary such that the pressured gas comes out of the tip.
