Oscillation magnetic equipment and biological sample oscillation magnetic attraction method

Abstract

The invention relates to vibration magnetic equipment and a biological sample vibration magnetic attraction method in the field of vibration separation equipment. The oscillation magnetic equipment comprises a base on which an oscillation mechanism, a lifting mechanism, a magnetic device and an oscillation adapter seat used for installing a sample seat are installed. The oscillation mechanism is connected with the oscillation adapter seat and drives the oscillation adapter seat to oscillate. The lifting mechanism is connected with the magnetic device and drives the magnetic device to ascend and descend. The magnetic device forms a magnetic field and ascends to act on a sample holder. One of the base and the oscillation mechanism is provided with an original point induction sensor, and the other one of the base and the oscillation mechanism is provided with an original point induction sheet for triggering the original point induction sensor. The oscillation magnetic equipment has the beneficial effects that the oscillation mechanism, the lifting mechanism and the magnetic device are integrated on the same base, the occupied space is reduced, and the experiment operation is simple and convenient; and the location of the oscillation adapter seat is realized through the matching of the original point induction sensor and the original point induction sheet, the alignment precision of the magnetic device and the oscillation adapter seat is ensured, and the improvement of the experiment quality is facilitated.

Description

technical field [0001] The invention relates to the field of vibrating separation equipment, in particular to an oscillating magnetic device and a method for vibrating and magnetically absorbing biological samples. Background technique [0002] Magnetic bead separation is a common separation method for separating samples such as nucleic acid, protein, or cells. The separation experiment involves shaking and magnetic absorption steps. Common automated liquid pipetting workstations generally set the oscillation and magnetic absorption at different stations. , takes up a lot of space. At present, there are also some devices that integrate vibration and magnetism, but the structure is complex, the positioning accuracy is low, and it is difficult to guarantee the quality of sample experiments.
