The magnetic rod sleeve is mainly used for nucleic acid extraction on the nucleic acid extraction instrument machine in combination with the deep hole plate. The process of nucleic acid extraction experiment protects the magnetic rod from contamination and extends the service life of the magnetic rod.

During the experiment, the mixing, cracking, binding, washing, and elution of the sample in the magnetic rod sleeve can realize the transfer of the magnetic bead and the separation of the magnetic bead, and the release of the magnetic bead and the target compound.
