  • Patent number: 11988682
    Abstract: A transfer system (1) is a transfer system (1) that transfers a sample container (S) containing a sample from a transfer source device (100) to a transfer destination device (200) disposed adjacent to the transfer source device (100), and the transfer system (1) includes an arm (2) having a distal end and a proximal end, the distal end portion facing the transfer destination device (200), and a first catcher (4) for detachably holding the sample container (S) at the distal end, a drive mechanism (14) provided in the transfer source device (100) and configured to drive the arm (2) to move the first catcher (4) between a first position in the transfer source device (100) and a second position in the transfer destination device (200), and a second catcher (16) provided in the transfer destination device (200) and provided so that the sample container (S) is delivered and received between the first catcher (4) and the second catcher (16) when the first catcher (4) reaches the second position.

  • Patent number: 7939032
    Abstract: 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.

  • Patent number: 7931789
    Abstract: 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.
