Magnetic Bead Applying in The Nucleic Acid Purification Apparatus
Magnetic therapy stick are constructed by strong permanent neodymium magnet with SUS 316L stainless steel shell. The working principle of the nucleic acid purification apparatus is to use the magnetic bead as the carrier, use the magnetic bead to adsorb nucleic acid under high salt and low PH value, and separate nucleic acid under low salt and high PH value, and then realize the entire extraction and purification process of nucleic acid by moving the magnetic bead or transferring the liquid. Because of its principle, it can be designed into many kinds of fluxes, which can be extracted in a single tube or 8-96 samples, and its operation is simple and fast. The extraction time of a batch is 9~40min (different samples and different manufacturers have different time), which greatly improves the experimental efficiency. Therefore, it can be used in different laboratories.
