- electrophoresis is used to analyze DNA, proteins, etc.
- a capillary electrophoresis device having capillaries is widely used.
- a capillary is a thin tube with a hollow structure, and an inner layer is formed of silica or the like to which charged functional groups are bonded. Liquid samples dispensed into microplates or microtubes are analyzed qualitatively or quantitatively in capillary electrophoresis devices.
- the tip of the capillary When analyzing a liquid sample, the tip of the capillary is inserted into the well of the microplate or the liquid sample in the microtube.
- a capillary is used in a state in which the inside is filled with a migration medium.
- a voltage is applied across the capillary, an electroosmotic flow is formed within the capillary.
- the components in the liquid sample are drawn into the capillary by electroosmotic flow, and are separated by their migration speed based on their charge and size while flowing through the capillary.
- the separated components are optically detected by a downstream detector in the capillary.
- capillary electrophoresis equipment is equipped with an autosampler that automatically performs analysis operations such as sampling.

- the protrusions 35 are arranged so as to sandwich the central side of the slit 40 from both lateral sides in the bottom view of the tubular portion 30 . Therefore, when the projection 35 receives pressure from the inner wall of the opening of the well 230, the bottom 34 of the lower cylindrical portion 32 is elastically deformed so as to close the slit 40 from both sides in the lateral direction, and is provided in a pre-opened shape.

Therefore, it is possible to suppress the evaporation of components from the container and the entry of contaminants into the container while allowing the insertion of the capillary into the container and the withdrawal of the capillary from the container. Therefore, sealing the container with the septa 1 enables accurate and stable analysis.
- the shape and structure of the slits 40 are different from those of the conventional general septa 100, so that the manufacturing process of the septa can be simplified.
- a slit 140 is provided in the bottom 134 of the tubular portion 130 .
- the cut slit 140 is formed by a punching process that penetrates the bottom portion 134 of the tubular portion 130 with a punch having a thin straight blade.
- the punches used for processing may have antirust oil, rust, and the like adhered thereto.
- the septa 100 during manufacturing may be handled in the air or come into contact with a punch with foreign matter attached, and the septa 100 may be contaminated. Therefore, a cleaning process for cleaning the septa 100 is required after the punching process.
- individual slits 140 are simultaneously formed in the bottom portions 134 of the plurality of cylindrical portions 130 arranged in a matrix.
- a plurality of slits 140 are formed by a punch in which straight blades are arranged in a matrix. At both ends of the cut slit 140, crack-like fracture surfaces are formed by penetrating thin straight blades.
- the cleaning process and the slit inspection process are incorporated into the septa manufacturing process, there is a problem that the manufacturing cost of the septa will increase. If the septa are to be liquid washed, a drying step is also required. The cleaning process, the drying process, and the slit inspection process require man-hours and equipment costs. In addition, since the slit 140 of the incision is almost completely closed unless a load is applied from the outside, inspection is troublesome due to poor visibility. In addition, if the slits 140 are poorly drilled, misaligned, or have dimensional defects, or if the tubular portion 130 is torn, even in some of the plurality of slits 140 and the tubular portion 130, the entire product will be defective. There is a problem that the yield per product becomes worse.
- the slits 40 are resin-molded in an open shape, so there is no need to incorporate the punching process, the cleaning process, and the slit inspection process into the septa manufacturing process. Since the slit 40 is resin-molded, it is possible to manufacture the septa 1 in a clean room without generating processing waste. The septa 1 during manufacture does not come into contact with contaminated working jigs or punches, and handling in air is reduced, thus eliminating the need for a cleaning step. Moreover, since the slit 40 is open in the non-loaded state, the dimensions and the like can be easily inspected.
- the manufacturing cost of the septa can be suppressed and the yield per product can be improved based on the peripheral structure of the slits into which thin tubes such as capillaries, needles, and nozzles 400 are inserted. can.
- the septa 1 based on the shape and structure of the cylindrical portion 30 and the shape and structure of the slit 40, the effect of reducing sample carryover in the automatic analyzer can be obtained.
- the liquid in the well 230 when the liquid in the well 230 is sucked by the thin tube or the liquid is discharged into the well 230 by the thin tube, the liquid may adhere to the side surface of the tip of the thin tube. Adhesion of liquid to a capillary causes liquid carry-over when the capillary is inserted into another well 230 . Carryover leads to sample concentration variations and cross-contamination. Therefore, it is necessary to remove the liquid adhering to the tip of the capillary and to wash the tip of the capillary.
- the slit 140 in the bottom portion 134 of the cylindrical portion 130 is provided as a linear cut. Therefore, when the capillary is withdrawn from the well 230, the inner walls of the cut slit 140 pushed away by pressure from the capillary try to return to their original state by elastic restoring force to such an extent that they come into close contact with each other. In such a process, the liquid attached to the side surface of the tip of the capillary tube can be wiped off to some extent by the inner wall of the slit 140 of the incision that tries to return.
- the bottom portion 134 of the cylindrical portion 130 provided with the cut slit 140 is thin enough for a punch with a thin straight blade to penetrate. If the inner wall of the slit 140 is thin, when the inner wall is pushed away by pressure from the thin tube, the elastic restoring force that tries to return to the original state is weakened. Therefore, the conventional general septa 100 does not have a sufficient effect of wiping off the liquid adhering to the side surface of the tip of the thin tube.
- the technique described in Patent Document 1 uses only the elastic force of the material deformed by pressure from the thin tube, so there is a possibility that the load applied to the side surface of the tip of the thin tube is not sufficient.
- the protrusions 35 are formed on the side surface of the tubular portion 30, and the protrusions 35 are pressed from the inner wall of the opening of the well 230, causing the slits 40 to move in the lateral direction. Since the slits 40 are elastically deformed so as to be closed from both outer sides, the elastic restoring force that tries to return the slits 40 can be strengthened more than before.
- the inner wall of the slit 40 is elastically deformed in the closing direction by being pressed against the protrusion 35 before being elastically deformed in the opening direction by the pressure from the capillary tube, when the capillary tube is pulled out from the well 230, the tip of the capillary tube is deformed.
- the load due to the elastic force on the side surface of the is stronger than before.
- the elastic load applied from the slit 40 to the tip of the thin tube can be adjusted, for example, by adjusting the shape, length, width, height, and arrangement of the protrusions 35, the thickness of the bottom 34 of the tubular portion 30, and the like. can be adjusted by doing Carryover can be reduced by adjusting the elastic load applied to the tip of the capillary tube to strengthen the action of wiping off the liquid adhering to the side of the tip of the capillary tube. Contamination can be suppressed.
- the slits 40 are resin-molded in a pre-opened shape, so that the durability of the peripheral structure of the slits 40 is improved compared to the case of the conventional slits 140 with cuts. can be improved. Even if an external force is applied to the protruding tubular portion 30 when attaching the septa 1 or storing the septa 1, tearing of the ends of the slits 40 and tearing of the tubular portion 30 are reduced. Therefore, the septa 1 having high durability can be obtained.
