Cartridge for biochemical analysis unit

摘要

A cartridge includes a cartridge main body and a filter unit. The cartridge main body contains a biochemical analysis unit of flow-through type, and includes a chamber into which a reaction solution is injected. The filter unit is used for the filtrating the reaction solution and fixed by screws to a bottom of the cartridge main body. The biochemical analysis unit is removably loaded onto a reactor main body in a situation that the cartridge is loaded. In setting the cartridge, the biochemical analysis unit and the filter are loaded, and therefore the loading mistake is prevented and the time for exchange of the filter is reduced.
