DEVICE FOR NUCLEIC ACID EXTRACTION USING MAGNETIC BEAD METHOD

摘要

The present invention provides a device for nucleic acid extraction using a magnetic bead method. The device includes a disc turntable in an inverted disc shape, an arc arch bridge base disposed right below the disc turntable, a supporting column connecting the disc turntable and the arc arch bridge base and disposed in the center of a disc along a vertical direction, and a magnet structural unit and a sample reaction unit which are arranged on the disc turntable. The disc turntable includes a top plate, and the top plate is sequentially provided with guide rod insertion holes and sample reaction unit insertion holes from the circumference to the circle center of the top plate; the arc arch bridge base includes a bottom plate arranged at the lowermost portion and an arc supporting plate arranged on the bottom plate, and the arc supporting plate corresponds to the guide rod insertion holes in position in a radial direction of the disc, and the arc supporting plate includes raised regions used for jacking up a guide rod and a magnet and groove regions used for allowing the guide rod and the magnet to fall. The device provided by the present invention can realize the automatic nucleic acid extraction in a stream-lining manner.
