The present invention provides reaction cells capable of maintaining stable analytical performance by preventing bubble adhesion and reducing sample carryover even if the amount of sample liquid for a single test is further reduced in the future. The invention further provides an automatic analyzer that uses the reaction cells and a method for enhancing the hydrophilicity of the inner surfaces of the reaction cells. According to the invention, a reaction cell has a first electrode inserted thereinto and a second electrode disposed on the bottom side of the reaction cell. A voltage is applied between the first electrode and the second electrode to cause electric discharge between the electrodes. This allows for enhancing only the hydrophilicity of the bottom inner surface and the four bottom corners of the reaction cell to which large bubbles adhere easily.
A method for manufacturing a reaction cell for use in an automatic analyzer, the method comprising the steps of:
A reaction cell for use in an automatic analyzer, the reaction cell having an inner bottom surface and inner side surfaces, wherein corners formed by the inner bottom surface and the inner side surfaces whose status is turned to be hydrophilic.
A reaction cell for use in an automatic analyzer, the reaction cell having an inner bottom surface and inner side surfaces, wherein the inner bottom surface and areas of the inner side surfaces below the lowest end of a photometric range whose status is turned to be hydrophilic.
A reaction cell for use in an automatic analyzer, the reaction cell having an inner bottom surface, wherein the inner bottom surface whose status is turned to be hydrophilic.
An apparatus for manufacturing a reaction cell for use in an automatic analyzer, the apparatus comprising:
