Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment mode, the patent of the present invention is described in further detail:

[0028] A heating and oscillating magnetic separation device includes three main modules, namely a magnetic separation module, a heating module and a vibration module. The magnetic separation module includes linear motors, lead screws, magnet brackets, and permanent magnets. The heating module includes electromagnetic pushers, springs, support plates, support columns, heating tanks, and heating films. The vibration module includes vibration motors and eccentric hammers. In addition, it also includes auxiliary structures such as bases, fixed plates, elastic columns and main frames.

[0029] The base is in the shape of a groove, and the middle part is fixed with a linear motor, an electromagnetic push-pull and a vibrating motor, and two fixing plates are placed on both sides of the middle.

[0030] The four corners of the fixing plate a...

Abstract

The invention discloses a heating and oscillating magnetic separation device, which comprises three main modules, namely a magnetic separation module, a heating module and a vibration module. The magnetic separation module includes linear motors, lead screws, magnet brackets, and permanent magnets. The heating module includes electromagnetic pushers, springs, support plates, support columns, heating tanks, and heating films. The vibration module includes vibration motors and eccentric hammers. The device drives the magnet bracket to move on the lead screw through a linear motor, thereby driving the permanent magnet to move up and down, and controls the relative position of the permanent magnet and the microporous plate to realize the reunion and dispersion of magnetic nanoparticles; the electromagnetic push-pull device pushes the support plate up and down Movement, and then drive the heating tank to move up and down through the support column, and control the distance between the heating tank and the hole wall of the microplate to realize the function of heating and closing. Finally, a fully functional, compact and easy-to-integrate biological sample processing device based on magnetic separation is realized, and the automation of the entire experimental process can be realized by using the robotic arm device.

Description

technical field [0001] The invention relates to biological sample processing technology, in particular to a high-throughput fully automatic heating and oscillating magnetic separation device. Background technique [0002] Biological samples are diverse and include plasma, serum, whole blood, lymph, saliva, various tissues, hair, urine, bile, tears, spinal fluid, sweat, milk, amniotic fluid, feces, and exhaled air. The research on biological samples first requires the pretreatment of biological samples, which usually requires fast and efficient operation of a large number of samples at one time. Therefore, appropriate biological sample processing and analysis equipment can greatly reduce the workload of researchers and improve work efficiency. , to better promote the development of disciplines. [0003] With the rapid development of nanoscience and technology, nanomaterials have been gradually applied to the field of life sciences, providing new technologies and means for th...
