Abstract: A resin tube connection device includes a resin tube, a resin expanding portion and a metal sleeve. The resin expanding portion has a sealing surface being able to come into contact with a contact surface. Further, the resin expanding portion has a second flow path that communicates with a first flow path of the resin tube and opens in the sealing surface. The sealing surface projects farther than an end surface of the metal sleeve in an axial direction. The maximum length of a contact region where the resin expanding portion and the metal sleeve come into contact with each other in the axial direction in an outer surface is larger than the thickness of a resin layer in a radial direction.

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.

Abstract: A pipe for a chromatograph includes a thin portion and a thick portion. The thin portion extends in one direction. The thick portion is located at an end portion of the thin portion in the one direction. The thin portion and the thick portion are integrally formed of a single member. The outer diameter of the thin portion is smaller than the outer diameter of the thick portion. The pipe is used in a chromatograph.

Abstract: A fluid port structure includes a tube and a cylindrical portion and receives injection of a fluid. The tube has sealability. A flow path through which the fluid flows is formed in the tube. In the cylindrical portion, a through hole that extends in an axial direction in which the fluid flows is formed. An upstream end portion of the tube is inserted into the through hole. An inner peripheral surface of the cylindrical portion has a tapered surface, and the more upstream a position on the tapered surface than a predetermined position in the axial direction, the larger a diameter of the portion of the through hole. The tube has a widening portion that widens along the tapered surface of the cylindrical portion in the upstream end portion.

Abstract: To suppress generation of dew condensation in temperature control space when heating temperature control is performed. In an apparatus, an air temperature control part for cooling or heating air in temperature control space has a first temperature control element for performing at least cooling of air, and a second temperature control element for performing at least heating of air downstream of the first temperature control element. In this manner, when heating temperature control is performed, cooling and dehumidification of air taken in from an air intake portion can be performed by the first temperature control element, and then heating of the dehumidified air can be performed by the second temperature control element.
