specific Embodiment approach 1

[0018] Specific implementation mode one: as Figure 1~3 As shown, the hot melt adhesive micro tissue homogenizer described in this embodiment is composed of a tube body 1 and a hammer body 2 inserted in the tube body 1, the tube body 1 is made of hot melt adhesive material, and the The hammer body 2 is a stainless steel hammer body.

[0019] The hot melt adhesive in this embodiment is a semi-elastic hot melt adhesive. The surface of the hammer body 2 and the internal surface of the pipe body 1 should be as smooth as possible, and the specification of the homogenizer can be scaled according to the working inner diameter φ3 of the pipe body from 3.0 to 10.0 mm. When selecting the specifications of the homogenizer, choose according to the volume of the sample to be processed. The pipe body 1 made of hot melt adhesive material and the stainless steel hammer body 2 are used together to achieve the close contact between the outer surface of the hammer body 2 and the inner wall of ...

specific Embodiment approach 2

[0021] Specific implementation mode two: as figure 2 As shown, the tube body 1 in this embodiment is composed of three parts: a circular tube-shaped opening section 1-1, a spherical body section 1-2 and a tube main body section 1-3. The circular tube-shaped opening section 1-1, the spherical body The section 1-2 and the main section 1-3 of the pipe body are arranged in sequence from top to bottom and the three are connected. The shape bottom cover 1-3-3 is formed, and the upper circular tube 1-3-1, the middle circular tube 1-3-2 and the hemispherical bottom cover 1-3-3 are arranged in sequence from top to bottom and the three are connected, and the upper circle The inner cavity of the tube 1-3-1 is a truncated cone that gradually converges inward from top to bottom, the inner cavity of the middle circular tube 1-3-2 is cylindrical, and the inner cavity of the upper circular tube 1-3-1 is in the same shape as The inner cavity of the middle circular tube 1-3-2 has a smooth tra...

specific Embodiment approach 3

[0022] Specific implementation mode three: as Figure 1~3 As shown, the diameter φ of the working section of the hammer body 2 in this embodiment is equal to the working inner diameter φ3 of the intermediate tube 1-3-2. The inner diameter of the working part of the pipe body should be the same as the working part of the hammer or slightly smaller than the diameter of the hammer, which can make the homogenization effect better. Other components and connections are the same as those in the second embodiment.

Abstract

The invention provides a hot-melt adhesive micro-tissue homogenizer, and relates to a microorganism tissue homogenizer, which solves the problem that the conventional microorganism tissue homogenizer is not good in crushing effect, high in consumption of treatment samples, long in crushing time, easy to rapidly heat treated samples so as to destroy certain components in certain samples. The hot-melt adhesive micro-tissue homogenizer consists of a pipe body (1) and a hammer body (2) inserted in the pipe body (1), wherein the pipe body (1) is made from hot-melt adhesive material while the hammer body (2) is a stainless steel hammer body. A gap between the pipe body (1) and the stainless steel hammer body (2) is approximate to zero so as to achieve the effect of homogenizing microorganisms such as plant pathogenic nematodes and nematodes, as well as other organisms and tissues. The homogenizer mainly applies to biological and life science laboratories, detection stations and the like for agriculture, forestry, medicine and the like.

Description

technical field [0001] The invention relates to a tiny biological tissue homogenizer. Background technique [0002] Researchers or testing personnel need to homogenize the samples before testing biological samples. Therefore, the homogenization of tiny organisms and their micro-tissues is a necessary process in various researches in agriculture, forestry, medicine, and many biological and life science research laboratories. For example, the determination of certain components of organisms or some tissues, the qualitative and quantitative analysis of chemical substances and pesticide residues in organisms, etc. In recent years, with the development of molecular biology, more and more experiments require the homogenization of organisms or parts of tissues to extract proteins and DNA and other biologically active substances for qualitative and quantitative comparative analysis. [0003] At present, the commonly used tissue homogenizers in the laboratory include manual glass t...
