PURPOSE: To efficiently pump mechanisms to a large number of test tubes by inserting the pump mechanisms or their parts through a test tube sealing body. CONSTITUTION: The pump mechanisms 20a to 20x are positioned at a first station and a slide 18 is ready to attach an index at a second station which is aligned perpendicularly below the 1st station. An array of test tubes 14 (14a to 14x) is arranged on a tray 16 mounted on the slide 18, and each test tube 14 is sealed with a rubber-made cap. Each pump mechanism 20 is equipped with a circular disk 26 and one or a plurality of hollow cannulas (stylus) extend downward from each disk 26 to form a liquid intake/outlet passage. The inside of a transport tube 32 communicates with one of the styli 28, and as the test tube is inserted through the sealing body 24 of a test tube 14 to operates bellows 30, the air in the test tube 14 is compressed discharge the content of the test tube 14 through the transport tube 32. |
