The utility model discloses a multi-hole site
nucleic acid mass spectrum adsorbent resin sample adding device, including: shell subassembly and adjusting subassembly, shell subassembly includes adjusting cylinder, adjusting hole, spring, row box, top hole, chute,
straw and finger groove, the circumference surface of adjusting cylinder is provided with adjusting hole, the inside of adjusting cylinder is provided with spring, row box, top hole, chute,
straw and finger groove, adjusting cylinder is provided with spring, row box, top hole, chute,
straw and finger groove. A row box is fixedly connected to the bottom of the adjusting cylinder, a top hole is formed in the top of the row box, and a sliding groove is formed in the inner wall of the row box. By arranging the shell
assembly and the adjusting
assembly, when resin adsorption is carried out, a pressing plate can be pressed to a specified scale, a
piston head moves downwards in a suction
pipe under the action of a movable plate and a connecting rod, then the suction
pipe is placed in a resin solution, after the pressing plate is loosened, resin enters the suction
pipe, and when the resin is injected, the pressing plate is pressed again; quantitative resin is extruded by observing the graduated scale, so that accurate feeding of
ion exchange resin particles into a plurality of PCR tubes at the same time can be realized, and errors among different reaction tubes are reduced.
