SIMULTANEOUS DILUTION OF PLURAL KINDS OF LIQUID

摘要

PURPOSE:To enable quantitative and continuous dilution to be made by sucking chemical liquids into diluting pressure liquid through more than two suction holes provided on a portion of the side wall of the differential pressure pipe passing said diluting pressure liquid while handling diluting magnification means. CONSTITUTION:Two suction holes 5a and 5b are provided in a portion of the suction device of the inner wall of the differential pipe 5 passing diluting pressure liquid so as to have smaller angles than 90 deg. with the upside of pipe axis and a relative angles of 60-180 deg. with each other. One 5a of said holes is communicates one liquid through the medium of a dilution magnification means 7, and the other 5b with another liquid through the medium of a dilution magnification means 8. The chemical liquid coming out of said hole 5a through said differential pipe 5 is diluted in range (a) and that coming out of said hole 5b in range (b), and both of said diluted chemical liquids are mixed with each other in range (c). Thus, quantitative and continuous dilution and mixation can be performed.
