Abstract

The invention provides an automatic magnetic bead separation device. A sleeve can rotate at low speed as required by an electric device, so magnetic beads precipitated at the bottom of a test tube cansuspend in a solution, and can be fully adsorbed onto the outer wall of the sleeve under the action of a magnetic bar conveniently. The electric device can also enable the sleeve to rotate at high speed, and the generated centrifugal force can effectively spin dry other materials or solutions attached to the outer wall of the sleeve. The automatic magnetic bead separation device also realizes anautomatic telescopic functional of the magnetic bar, so the magnetic bar is ensured to be in full contact with the bottom of the sleeve, and further the attractive force on the magnetic beads at the bottom of the test tube is improved. The automatic magnetic bead separation device can effectively solve the problem in the prior art that the magnetic bead recovery rate is low and is likely to causetowing contamination. The automatic magnetic bead separation device can flexibly adapt to different sizes of sleeves, thereby meeting the requirements for simultaneous computer operation of differentspecifications of sample test tubes.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an automatic nucleic acid extraction equipment. Background technique [0002] Nucleic acid is the core of genetic information expression in the genome and an important object of life science research. With the continuous development of science and technology, the field of clinical molecular diagnosis has put forward higher and faster requirements for the rapid extraction of nucleic acids. [0003] At present, there are fully automatic nucleic acid extraction equipment that use the magnetic bead method to extract nucleic acid on the market. The specific method is that in the first step, the sample solution, lysate, and magnetic beads are added to several test tubes, and the cells in the sample are lysed under the action of the lysate or high temperature, and the isolated nucleic acid and magnetic beads achieve specificity. Combine; the second step inserts several (equal to the numbe...
