Embodiment Construction

[0044] use figure 1 as well as figure 2 One embodiment of the automatic sealing device will be described.

[0045] This automatic sealing device 1 maintains airtight and liquid tight and automatically connects the piping 7 with respect to the flow path plate 4 provided with the internal flow path 4b and a hole 4a communicating with the internal flow path 4b on one surface thereof. device. A plate installation portion 2 a on which the flow channel plate 4 is placed is provided at a lower portion of the frame body 2 . In this embodiment, the flow channel plate 4 is configured such that the surface provided with the holes 4a faces upward, however, the present invention is not limited thereto. Alternatively, the surface provided with the hole 4 a may be arranged to face a direction other than upward, and the sealing member 8 may be configured to be pressed vertically against this surface.

Abstract

The invention provides an automatic sealing device which is capable of connecting a tubing to an internal flow path of a flow path plate with high airtightness even without a motor generating high torque. The automatic sealing device comprises a driving body which holds a tubing in such as manner that the top end of the tubing is opposite one surface of a plate; the top end side of the tubing is provided with a sealing component surrounding the periphery of the top end portion of the tubing and is connected to one surface of the plate in a manner of surrounding a hole when the tubing is connected to the hole. The driving body can move in a direction perpendicular to one surface of the plate. The driving body comprises a screw provided with a thread in the external peripheral surface, a screw rotating mechanism making the screw rotate, a moving part moving in the axial direction of the screw along with the rotation of the screw and a link mechanism drive connecting the moving part and the driving body and enabling the force from the moving part to increase and to be transmitted to the driving body.

Description

technical field [0001] The present invention relates to an automatic sealing device for connecting the ends of pipes and nozzles airtightly to connection holes provided on the surface of a flow channel plate in which a flow channel is formed. As the channel plate, for example, a tray whose channel becomes an analytical column of gas chromatography / liquid chromatography, an analysis plate including a reaction vessel and the like in the channel, and a microplate for electrophoresis, and the like are exemplified. Background technique [0002] Generally, holes communicating with the internal flow channels are provided on the surface of a flow channel plate having fine flow channels inside, such as a microplate for electrophoresis. In order to inject liquid into the internal channel of the channel plate, it is necessary to connect pipes in a liquid-tight manner to the holes on the surface communicating with the internal channel, and to apply high pressure to feed the liquid. The...
