Material taking device for plant cell paraffin section

Abstract

The invention belongs to the technical field of biological sectioning, and particularly relates to a plant cell paraffin sectioning sampling device which comprises a mounting base frame, guide sliding rails are fixedly mounted on the upper surfaces of the left end and the right end of the mounting base frame, notches are formed in the surfaces of the sides, away from each other, of the two guide sliding rails, and electric push rods are fixedly mounted at the rear ends of the guide sliding rails; a sliding push plate is arranged over the two guide sliding rails. The plant sample is subjected to subsequent treatment such as fixation, washing and dehydration according to the observed plant cell morphology, the plant sample is subjected to equal-interval sectioning treatment, so that an operator can conveniently perform paraffin sectioning treatment on cells at different positions of the plant sample, and the sectioned plant port is subjected to sectioning treatment; by means of the device, an operator can conveniently and preliminarily observe cells in different areas of a plant, the success rate of sample plant paraffin section is greatly increased, the tedious operation of material taking in the existing plant paraffin section manufacturing process is effectively solved, and the plant paraffin section efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of biological tablets, and in particular relates to a material sampling device for paraffin sections of plant cells. Background technique [0002] Paraffin section is the most widely used method in the routine preparation technology of histology. Paraffin section is not only used to observe the morphological structure of normal cell tissue, but also the main method used by pathology and forensic science to study, observe and judge the morphological changes of cell tissue. , and has also been widely used in research in many other disciplines, the most widely used method in the routine preparation technique of paraffin section histology. [0003] After leaving the body, the tissue will soon die and cause tissue corruption, losing its original normal structure. Therefore, the tissue must be fixed, paraffin-embedded, sectioned, and stained to avoid cell death, and its morphological structure can be clearly ident...

AI Technical Summary

Problems solved by technology

[0003] Tissues will soon die and decay after leaving the body, and lose their original normal structure. Therefore, the tissue must be fixed, paraffin-embedded, sectioned, and stained to avoid cell death and to clearly identify its morphological structure. When performing paraffin sectioning of plant tissues, it is necessary to take samples from different regions of the plant samples. Traditionally, operators need to hold cutting tools to cut into sections. Due to the need to sample different positions of plant samples, the workload is large and the sampling specifications are difficult. To be uniform, to bring inconvenience to plant paraffin sections
