Description

Direct insertion type magnetic rod sleeve assembly

Technical Field

The utility model relates to a nucleic acid draws technical field, specifically is a formula bar magnet cover subassembly cut straightly.

Background

With the rapid development of the medical field, more and more nucleic acid-based biological experiments are emerging, and the extraction and detection of nucleic acids can help to make rapid diagnosis of the disease of patients. The magnetic bead method is a novel nucleic acid extraction technology with nano biological magnetic beads as carriers, nucleic acid molecules can be specifically identified and combined with silicon hydroxyl on the surfaces of the magnetic beads, and are aggregated or dispersed under the action of an external magnetic field, so that the nucleic acid is separated and purified. The magnetic rod sleeve is matched with the deep hole plate for use and is mainly adapted to a nucleic acid extractor. In the nucleic acid extraction process, the magnetic rod sleeve mainly has the functions of separating liquid from the magnetic rod, protecting the magnetic rod from being corroded by the liquid and prolonging the service life of the magnetic rod. When the magnetic bead method reagent is used for nucleic acid extraction, the magnetic rod sleeve moves up and down, so that the sample is uniformly mixed, cracked, combined, washed and eluted. In the nucleic acid extraction process, the magnetic bar and the magnetic bar sleeve move coordinately to realize the transfer of magnetic beads and magnetic bead-extract complex. When the magnetic rod is separated from the magnetic rod sleeve, the magnetic beads and the magnetic bead-extract complex are released.

At present, the combination is assembled to bar magnet cover sequence as required to present formula bar magnet cover subassembly, make bar magnet cover subassembly can satisfy the demand of using same platform equipment single operation to handle many copies of samples, however this kind of mode has reduced the intensity of bar magnet cover subassembly, lead to taking place to warp after assembling easily, cause each bar magnet cover to appear the crooked condition, cause bar magnet cover subassembly unable use, there is certain defective rate, and the fixed effect of bar magnet cover is relatively poor, lead to the bar magnet cover to deviate from easily in the high frequency motion of nucleic acid extraction instrument, the influence draws the normal clear of work, consequently, certain improvement space still.
