A microchip processing apparatus processes a microchip with at least one main separation channel. The microchip processing apparatus includes a holding part configured to hold the microchip, a container containing a sample or a reagent, and a dispensing probe having a needle formed on a tip of the dispensing probe. The dispensing probe is actuated to be inserted into the container from above the container, to draw the sample or reagent, and to inject to a prescribed position on the held microchip. A dispensing probe driving mechanism moves the dispensing probe between prescribed positions of the microchip and the container.

Microchip processing apparatus

In a separation buffer solution filling device, a microchip is arranged such reservoirs are opened on a surface on respective ends of channels including at least a main separation channel in which analysis is performed while a solution moves inside a plate-like member, and the reservoirs face upward. The filling device fills separation buffer solution into the channels by supplying air from an air supply port which is pushed while maintaining air-tightness onto a top of the reservoir filled with the separation buffer solution on either end of said channels. The air supply port is an opening on a front end of an air cylinder, and has a seal part on that opening. The filling device is pushed onto the reservoir while maintaining air-tightness by that seal part.
