Slicing device for laboratory biological research

Abstract

The invention discloses a slicing device for laboratory biological research, and relates to the field of laboratory biological slicing. The slicing device comprises a base, a sample fixing frame movably connected to the middle of the upper portion of the base, a cold air generating device arranged on one side of the upper portion of the base, a cold air conveying device arranged in the base and on the sample fixing frame, and a flattening device movably arranged on the side, away from the cold air generating device, of the base. The cold air conveying device comprises an air guide ring fixedly installed on the outer side face of the open end of the sample fixing frame and an air guide pipe communicating the air guide ring and the cold air generating device, one end of the air guide pipe is fixedly connected to the side face of the air guide ring, and the other end of the air guide pipe is fixedly connected to the air outlet end above the cold air generating device; an annular groove is formed in the inner side of the opening of the sample fixing frame; According to the slicing device, cold air is utilized more sufficiently, the sample cooling effect is better, sample slices cannot form rolled slices, meanwhile, wrinkles cannot occur, and the good flattening effect on the sample slices is achieved.

Description

technical field [0001] The invention belongs to the field of laboratory biological slicing, in particular to a slicing device for laboratory biological research. Background technique [0002] In the process of biological research in the laboratory, biological samples will be sliced ​​and then observed with a microscope. Since the hardness of the biological sample itself is low, and the hardness of each part of itself is not the same, which affects the quality of the slice, it is necessary to increase the hardness of the sample before slicing. Process, and make the internal hardness of the tissue uniform. [0003] The commonly used ways to increase the hardness of samples are freezing method and paraffin method, and then use the slicing device to slice the frozen samples or paraffin-wrapped samples. During the slicing process, the sample slices will have the problem of rolling. Usually the existing solution is Manually use a hand-painted pen to flatten the sample slices. Dur...
