Purifier HTS automatic nucleic acid extractor adopts magnetic beads separation technology (the Fig 1. ). The disposable magnetic rod tip comb is loaded on the magnetic rod, and then the magneticbeads are transferred between the deep hole plates containing specific reagents through the separation of themagnetic rod and the magnetic rod tip comb, so as to realize the collection, release, transfer and incubationof the magnetic beads. Different from the traditional nucleic acid extractor, Purifier HTS contains twoheating plates and two standard plates. Only four plates can complete the complete steps of nucleic acidextraction by magnetic bead method, so as to realize the high-quality extraction of nucleic acid inthesample, which greatly shortens the extraction time.
