PURPOSE:To achieve an injection/discharge operation of an antigen or antibody, cleaning operation of an reacted substances and the like accurately in a short time, by using a transparent tubule having a capillary part with the inner diameter of below 2mm as reaction container and a solid phase. CONSTITUTION:An entire tubule is formed as capillary tube 1 and a water permeating septum 2 with the bore diameter smaller than the inner diameter of below 2mm of the capillary tube 1 is provided at the lower end of the capillary tube 1 whereby a plenty of solution 3 can be held within the capillary tube 1. Here, the water permeation means the characteristic that facilitates the passage of a solution by rendering the inside of the capillary tube 1 a negative or positive pressure where the septum 2 is amounted on the capillary tube 1. The 2 septum herein used may be in the form of a film, an sponge or in a mesh. The amount of the solution 3 to be held within the capillary tube 1 can be increased even by giving the lower end of the capillary tube 1 a shape with an opening 4 with the inner diameter smaller than other parts.
