CYLINDRICAL CHANNEL HAVING SAW-TOOTHED CROSS SECTION AND PREPARATION METHOD OF THE SAME CHANNEL

摘要

PURPOSE: A cylindrical channel for a micro fluid chip, a method for manufacturing the same, a coaxial channel including the cylindrical channel, and a method for manufacturing the coaxial channel are provided to improve the performance of a mixer or a uniform agitator by inducing unstable fluid. CONSTITUTION: A cylindrical channel for a micro fluid chip includes saw-toothed grooves on the cross section. The cross section of the cylinder channel is tapered or constant. The thicknesses of the grooves are in a range between 3 and 15um. The widths of the grooves are in a range between 5 and 15um. Gaps between the grooves are in a range between 10 and 20um. A method for manufacturing the cylinder channel includes the following: a film is located on a base mold with a mold groove and a pressure adjusting hole; and pressures to the film are adjusted to arrange a plurality of saw-toothed grooves on the upper side of the film.
