Abstract
The present invention relates to a disposable separation chip used when separating magnetic beads present in a mixed solution using magnetic force. The present invention provides disposable separation chip including a lower chip on which a wire pattern having a parabolic shape from one side to another side thereof is formed; and a separation chip separable from the lower chip, wherein the separation chip includes: an upper plate on which a coupling portion coupled to a tubing is formed; and a first member disposed under the upper plate and coupled to a lower surface of the upper plate, wherein the coupling portion is integrally produced with the upper plate wherein it is formed through the upper surface and the lower surface of the upper plate to be connected to a channel.
Claims14
A disposable separation chip comprising:
- a lower chip on which a wire pattern having a parabolic shape from one side to another side thereof is formed;
- and
- a separation chip separable from the lower chip,
- wherein the separation chip comprises:
- an upper plate having a coupling portion for connection to a tubing;
- and
- a first member disposed under the upper plate and coupled to a lower surface of the upper plate,
- wherein the coupling portion comprises:
- a depression portion formed on an upper surface of the upper plate;
- a pipe portion entirely located within the depression portion and configured to be inserted into the tubing;
- and
- a connection portion that connects an inner circumferential surface of the pipe portion to a channel,
- wherein the pipe portion forms an acute angle with respect to the upper surface of the upper plate, an upper end of the pipe portion comprising a cut edge parallel with the upper surface of the upper plate, and a stopper portion having a diameter equal to or greater than the tubing is formed perpendicular to a center axis of the pipe portion such that the tubing is inserted at a constant depth,
- wherein the depression portion, the pipe portion, and the connection portion are integrally formed with the upper plate such that the coupling portion extends from the upper surface to the lower surface of the upper plate to be connected to the channel, and
- wherein the height of the upper end of the pipe portion is equal to the upper surface of the upper plate.
