Abstract:
1. A biological material fixed carrier enclosing tip comprising: a tip form vessel having an installation opening part that is installable to a nozzle that performs suction and discharge of gas, and a narrow tube that is insertable into various vessels and possesses an opening, through which fluid inflow and outflow is possible by means of said suction and discharge of gas, that is narrower than said nozzle; a carrier in which a predetermined biological material is fixed or fixable in a plurality of different positions that are determined beforehand that are distinguishable from the exterior, and has a size or a shape that is able to pass through said opening; and an enclosing section provided on said tip form vessel that encloses the carrier within the narrow tube in a state where it is able to make contact with the fluid that has flown into said narrow tube from said opening, wherein said tip form vessel has a storage section that communicates said installation opening part and the narrow tube, in which liquid is storable, wherein said narrow tube is provided with respect to said storage section, as a separate body, such that the upper side of the narrow tube is provided with respect to an engage section of said storage section, wherein said carrier has a plurality of particle form carriers, wherein said enclosing section is provided such that it sandwiches said plurality of particle form carriers at two adjacent positions within the narrow tube in a state where the particle form carriers are trapped along the direction of fluid inflow and outflow and are serially arranged such that the order thereof becomes constant within the narrow tube, and the plurality of different positions determined beforehand are made to correspond to said plurality of particle form carriers that are arranged in a predetermined order, wherein said enclosing section has a first carrier passage blocking member and a second carrier passage blocking member such that an interval between the first carrier passage blocking member and the second carrier passage blocking member is greater than the length of the plurality of particle form carriers, wherein the first carrier passage blocking member protrudes radially inwardly from an inner wall face of said tip form vessel to block the plurality of particle form carriers from exiting the opening of the narrow tube while permitting relative movement between the plurality of particle form carriers and the first carrier passage blocking member, wherein the first carrier passage blocking member is entirely within the narrow tube so that at least a portion of the narrow tube extends between the first carrier passage blocking member and the opening of the narrow tube, and wherein an inner diameter of the narrow tube is greater than an outer diameter of the plurality of particle form carriers and less than twice the outer diameter of the plurality of particle form carriers.
