Method of manufacturing a reaction cuvette for use in an automatic analyzer and apparatus for manufacturing a reaction cuvette

摘要

The present invention provides reaction cells (21) 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 (21) and a method for enhancing the hydrophilicity of the inner surfaces of the reaction cells. According to the invention, a reaction cell (21) has a first electrode (33) inserted thereinto and a second electrode (34) disposed on the bottom side of the reaction cell (21). A voltage is applied between the first electrode (33) and the second electrode (34) 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.
