Embodiment 1

[0031] Embodiment 1: This embodiment discloses a small amount of metal tissue grinding device, including a metal block 1 and a metal grinding wheel 2 as a base, the metal block 1 is provided with a plurality of grinding grooves 3, and the grinding groove 3 In the extending direction of the length, the middle part of the depth of the grinding tank 3 is the deepest, and the two ends gradually become shallower; the metal grinding wheel 2 is provided with a handle 4, and the lower end of the handle 4 separates two metal grinding wheels 2 The branches 5 on both sides, the ends of the branches 5 are connected by a cross bar passing through the center of the metal grinding wheel 2, the metal grinding wheel 2 rotates with the cross bar as the axis, and the grinding tank 3 One end extends to the side of the metal block 1 and forms a discharge port 16 . In another more preferred embodiment, the side of the metal block 1 is provided with a protruding extension at the position correspondi...

Embodiment 2

[0036] Embodiment 2: This embodiment discloses a small amount of metal tissue grinding device, including a metal block 1 and a metal grinding wheel 2 as a base, the metal block 1 is provided with a plurality of grinding grooves 3, and the grinding groove 3 In the extending direction of the length, the middle part of the depth of the grinding tank 3 is the deepest, and the two ends gradually become shallower; the metal grinding wheel 2 is provided with a handle 4, and the lower end of the handle 4 separates two metal grinding wheels 2 The branches 5 on both sides, the ends of the branches 5 are connected by a cross bar passing through the center of the metal grinding wheel 2, the metal grinding wheel 2 rotates with the cross bar as the axis, and the grinding tank 3 One end extends to the side of the metal block 1 and forms a discharge opening 16, and the side of the metal block 1 is provided with a protruding extension at the corresponding position of the discharge opening 16, a...

Embodiment 3

[0039] Embodiment 3: This embodiment is basically the same as Embodiment 2, the difference is that it also includes a slant frame 9, and the slant frame 9 includes a slant platform 10, a plurality of supporting feet 11 arranged under the slant platform 10 and connecting The connection bar 12 of two adjacent supporting legs 11. The inclined table 10 has a certain inclination, and has a certain height through a plurality of supporting feet 11, which is convenient for the operator to exert force for grinding. The metal block 1 has a certain inclination. After the grinding is completed, the grinding tank 3 with a certain inclination makes it easier to scrape out the ground sample with a spatula and transfer it to the centrifuge tube.

[0040] Moreover, in order to better fix the metal block 1 on the inclined platform 10, the inclined platform 10 is provided with a sinking groove 13, the shape of the sinking groove 13 is adapted to the shape of the metal block 1, and the The depth...

Abstract

The invention discloses a small amount of metal tissue grinding device, which comprises a metal block and a metal grinding wheel. The metal block is provided with a plurality of grinding grooves; the metal grinding wheel is provided with a handle, and the lower end of the handle is divided into two separate metal grinding wheels. The branches on both sides of the wheel, the ends of the branches are connected by a cross bar passing through the center of the metal grinding wheel, the metal grinding wheel rotates with the cross bar as the axis, and one end of the grinding groove extends to the side of the metal block and forms a discharge port. Based on the premise that liquid nitrogen instantly solidifies a small amount of animal and plant tissue samples at ultra-low temperature, the solid samples are repeatedly rolled by using the hardness of metal blocks and metal grinding wheels that are difficult to deform, so as to solve the problem of tissue samples in the grinder grinding method or porcelain mortar grinding method. Insufficient grinding, especially the hard or flexible tissue samples are difficult to achieve the ideal degree of grinding under normal temperature conditions of the grinder, and the porcelain mortar is easy to remain in the grinding process.

Description

technical field [0001] The invention relates to the technical field of biomolecular experiments, in particular to a small amount of metal tissue grinding device. Background technique [0002] Nucleic acid and protein extraction are required for molecular related experiments such as animal and plant genetic metabolism. The quality of sample grinding preparation during extraction is a prerequisite for good extract quality. The existing grinding methods mostly use porcelain mortar and high-throughput tissue grinder to grind samples, but these two grinding methods cannot completely grind hard or flexible tissues during the grinding process, resulting in The extraction effect or yield of nucleic acid, protein and other molecules in the sample is not good. During the grinding process of the porcelain mortar, it is easy to cause insufficient grinding of the sample due to the temperature rise of the mortar during the continuous grinding process; the grinding friction of the porcel...
