Abstract: A sample cooling device is provided with, inside a sample storage which stores therein a sample rack, a first heat transfer member arranged at a position in contact with the sample rack, a second heat transfer member which cools the inside of the sample storage, and a condensate discharge mechanism which discharges condensate condensing on the second heat transfer member to the outside of the sample storage. An internal space of the sample storage is not sealed due to the existence of a leak path for air formed between the inside and the outside of the sample storage, the leak path including at least the channel. The sample storage includes an outside air introduction unit which forcibly blows the outside air into the internal space so that the pressure inside the sample storage becomes higher than the outside pressure thereof. The position and the direction of an outside air outlet of the outside air introduction unit inside the sample storage are set so that the outside air blown into the sample storage directly heads for the second heat transfer member.

Abstract: A flow channel switching valve is provided including a stator and a rotor inside a housing, in which the rotor is rotated by a rotor drive portion while sliding on the stator. A rotor drive shaft holding the rotor is biased to a housing top side by an elastic member. A drive shaft stopper is provided that limits movement when the rotor drive shaft moves to the housing top side from a normal position when a housing top is attached to a housing body.

Abstract: A bioinert pipe includes a flow path inside, an inner wall of the flow path is composed of a resin tube and an outer peripheral surface of the resin tube is covered with a metal tube. The bioinert pipe includes an end portion extension member attached to an end portion of the metal tube, and the end portion extension member is made from a material harder than the resin tube and has a first surface and a second surface. The first surface is facing and in contact with an end surface of the metal tube and the second surface is directed opposite to the first surface. a through hole having an inner diameter substantially the same as an inner diameter of the metal tube is provided so as to pass from the first surface to the second surface in the end portion extension member. An edge of the through hole on the second surface of the end portion extension member has a chamfered shape, and the resin tube is inserted into the through hole. An end portion of the resin tube forms a flange portion by being by being bent outward in a radial direction of the flow path along the chamfered shape of the edge of the through hole.

Abstract: A resin tube is prepared. Further, a formation tool having a pressing surface and a projection that projects from the pressing surface and is insertable into the resin tube is prepared. The projection of the formation tool is inserted from an end of the resin tube into the resin tube. The pressing surface of the formation tool is pressed against an end surface of the resin tube. Thermal energy is applied to the end of the resin tube, whereby a shape of the pressing surface of the formation tool is transferred to the end surface of the resin tube, and the end of the resin tube is formed into a flange shape.

Abstract: To suppress inflow of external air through a rack insertion opening while a sample rack is pulled out. An apparatus includes a housing, a temperature control space, and an air temperature control part. The housing has the rack insertion opening on one side surface for putting in and taking out the sample rack. The air temperature control part has an air intake portion for intake of air in the temperature control space, a fan for blowing air taken in from the air intake portion toward the sample rack accommodated in the temperature control space, and a cooling element provided to cool the air on a path of air taken in from the air intake portion. The air temperature control part is configured to reduce an amount of air flowing near the rack insertion opening while the sample rack is pulled out from the temperature control space as compared to while the sample rack is accommodated in the temperature control space, so as to suppress inflow of air through the rack insertion opening.
