摘要： A plug unit for connecting capillary tubes includes a plug housing that has an axial borehole, a plug capillary tube that projects through the axial borehole, and a sealing element that surrounds the plug capillary tube. The front end of the plug capillary tube is sealed by an elastic and/or plastic deformation of the sealing element against the capillary tube receptacle opening of a bushing unit. A hollow cylindrical pressure piece is provided that surrounds the sealing element in an axial region facing away from the end surface of the plug capillary tube, and the pressure piece has a rearward end side that faces away from the end surface of the plug capillary tube and that can be loaded by the plug housing with an axial pressure force when the plug unit and bushing unit are connected.

摘要： A fluidic device includes a planar structure constituted by a plurality of laminated layers and accommodating a fluid channel extending up to a surface of the planar structure, and a female adapter piece configured for a fluid-tight accommodation of a male adapter piece having a fluid conduit. The the female adapter piece is connected or connectable with the planar structure so that, when the male adapter piece is accommodated in the female adapter piece, the fluid conduit is brought in fluid-tight fluid communication with the fluid channel. The fluid channel is exposed to the female adapter piece at a lateral surface of the planar structure at which the laminated layers are exposed.

摘要： A multi-walled tube that is useful as an analytical column in which chemical mixtures can be separated into their individual components is described. In order to be acceptable as an analytical column, the inner surface of the multi-walled tube must support effective separation, but not react chemically with or contaminate the solvent or the analyte (sample to be separated). Grade 316 stainless steel is typically preferred for this purpose. Moreover, the inner diameter (ID) surface of the multi-walled column is preferably very smooth (less than 10 micro inch Ra) with no interruptions in the surface such as scratches, pits, or asperities. However, since the column is designed to be attached to chromatographic equipment using standard size connection features, the size of standard fittings define the outer diameter (OD) of the column.

摘要： A manifold assembly has a manifold and can be located between a block and a plate, and serve as a stator for a valve or other component. The manifold, block or plate can have a plurality of ports either integral thereto or removably connected thereto, with the ports adapted to receive and sealingly engage with a tube having an inner tube layer, an outer tube layer, a sleeve, a tip portion, and a nut. Each of the nut, sleeve, inner and outer tubing layers, and tip portion have a passageway therethrough, with at least the passageways in the sleeve, tip portion, outer tube layer, and nut adapted to allow the inner tube layer to pass therethrough or extend over the inner layer. The ends of the tip portion and inner layer together can define a substantially flat surface which can form a seal in a flat-bottomed port of the manifold, block, or plate, which can be used in a component in an analytical instrument system, including for example a liquid chromatography system. The nut, tube, ferrule, and transfer tube or liner tube may comprise biocompatible materials. In addition, the nut may have a slot, such as a slot adapted to allow the tube and the nut to be easily and quickly separated or to allow a portion of the tube to be easily and quickly inserted in the nut.

摘要： A ferrule 10 is pressed by a pressing plate 35, and the ferrule 10 is thereby sandwiched and fixed between a ferrule receiving part 20 and ferrule pressing part 30. The pressing plate 35 is displaced by a displacing mechanism 350, whereby the pressing plate 35 is switched between a contacting state in which the pressing plate 35 is in contact with the ferrule 10 and a non-contacting state in which the pressing plate 35 is not in contact with the ferrule 10 and the ferrule 10 can pass thorough the inside of the ferrule pressing part 30. By displacement of the pressing plate 35 to the non-contacting state, the ferrule pressing part 30 can be extracted from the ferrule 10 side, and the ferrule pressing part 30 can therefore be removed from a column 2 in a state in which the ferrule 10 is attached in a swaged fashion.

摘要： A torque limited fitting is provided having a head and a body, which in certain embodiments may be assembled by an operator. The body of the torque limited fitting has a passageway therethrough for receiving and removably holding tubing. The torque limited fitting may be adapted for use with a flat bottom port, such as in an analytical instrument, like liquid chromatography, gas chromatography, ion chromatography, or in in vitro diagnostic systems.
