  • Apparatus and method for extracting biologically active substances through magnetic beads method
    Patent number: 9970952
    Abstract: The present invention provides an efficient apparatus for extracting biologically active substances through a magnetic particle method, comprising a magnetic needle, a magnetic needle moving mechanism, a sleeve and a sleeve moving mechanism and a vibration mechanism, a bracket, a positioning mechanism; the vibration mechanism is capable of generating vibrations to enable the sleeve moving mechanism to make upward and downward vibrations; wherein the magnetic needle can vertically insert into and move out of the sleeve; the sleeve can vertically insert into and move out of a sample treatment area; and the vibration mechanism comprises a lever bar, a movable fulcrum and a rotary mechanism. The present invention further provides an instrument comprising the apparatus for extracting biologically active substances. The present invention further provides a method for extracting and purifying biologically active substances using the apparatus or the instrument for extracting biologically active substances.
