PROBLEM TO BE SOLVED: To provide a microarray preparing device capable of printing dots on a sample plate at a high density and at high-accuracy pitches. SOLUTION: This microarray preparing device is equipped with a housing 301 having a circular peripheral groove 302, a discharge port 3011 opened so as to allow a sample to be pushed out from a part of an inner wall surface of the housing to the sample plate 1, a sample liquid push-out means for pushing out a fixed amount of sample liquid 9 from the discharge port with a roller 305 revolving along an inner wall of the peripheral groove while making rolling contact therewith, and a screen member formed with integrally the bottom part of the housing 301 and having permeable holes for printing a dot pattern of the sample liquid 9 by using the pushed-out liquid 9 with the other portions being impermeable. |
