Cartridge for biochemical use and biochemical processing device
A cartridge sealed from an external air is used to enable mixing with a reagent, agitating, purification, reaction, etc. Provided inside the cartridge sealed from the external air are a chamber for the reagent to be transported, a chamber to which the reagent is transported, and the chambers are connected by a liquid transport channel. A groove is made in a cartridge body and a membrane as an elastic body is pasted onto the groove to form the liquid transport channel. Air pressure is given to the membrane to change the volume of the liquid transport channel and thereby move the fluid inside. The inlet of each chamber has a valve function to move the fluid inside in a desired direction according to change of the liquid transport channel. This enables transportation of the liquid inside the cartridge sealed from the external air.
