Problems solved by technology

In addition, after transferring the liquid in the centrifuge tube with a pipette gun to achieve magnetic separation, there will still be a small amount of liquid or other impurities remaining on the centrifuge tube wall, which remain in the centrifuge tube together with the magnetic material and are not transferred to a clean centrifuge tube, resulting in Subsequent magnetic materials are still not pure enough after elution

Embodiment Construction

[0041] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0042] Such as Figure 1 ~ Figure 4 As shown, the manual magnetic solid phase extractor of the present invention includes a gun body 1 , a gun body head 2 , a fixed handle 3 , an operating rod 4 , a magnetic rod 5 , a magnetic tube 6 and a magnetic tube cover 7 .

[0043] The gun body 1 is a hollow structure with upper and lower openings. Preferably, the gun body 1 is a cylindrical structure with a diameter of 2.5-3.5 cm, which is convenient to hold by hand. The bottom of gun body 1 is connected with gun body head 2. A second baffle plate 8 is fixedly arranged near the upper part of the gun body 1 for fixing the position of the upper end of the operating lever spring 15 and locking the operating lever 4 . A third baff...

Abstract

The invention discloses a manual magnetic solid extractor. The manual magnetic solid extractor comprises a gun body, a gun body head, an operating rod, a magnetic bar, a magnetic tube and a magnetic tube sleeve. The manual magnetic solid extractor is simple and convenient to use, is particularly suitable for separating and transferring magnetic materials in a 5 to 50mL of tubular vessel and is applicable to the research fields of immune cell separation, proteomics separation, immobilized enzyme, biomechanical engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of magnetic separation, and in particular relates to a manual magnetic solid-phase extractor. Background technique [0002] Magnetic separation technology is more and more widely used in research fields such as immunology, proteomics, biomedical engineering and environmental protection, such as immobilization of proteins and enzymes, immunoassay, purification of tagged proteins and DNA, cell separation and drug carrier, etc. Compared with commonly used separation methods such as precipitation, centrifugation, ion exchange and various chromatographic methods, magnetic separation technology has the characteristics of convenience and quickness, simple equipment required, fast separation speed and high extraction efficiency, which is conducive to maintaining the properties of samples , especially the advantages of biological activity. [0003] The magnetic separation rack is a magnetic separation device with s...
