Problems solved by technology

[0005]With the increase in the number of analyzed samples, the manual chromosome disperser is increasingly unable to meet the needs of daily analysis work
Japan's Hanabin Company developed the Metaphase Auto-spreader, an automatic chromosome dripping instrument, which basically solved the high-throughput problem of chromosome preparation. However, the system is a vertical machine with large volume, complex structure, and high energy consumption. Production and use and high maintenance costs

Description

technical field [0001] The invention relates to a biological sample experimental device, which is suitable for the technical fields of automatic droplet operation and cytogenetic experiment in the biological sample preparation process. Background technique [0002] According to classical cytogenetics, chromosomes prepared from cells can be analyzed under a microscope to diagnose possible defects. Chromosome preparation requires the harvested cells to be treated with hypotonicity, fixation, drying, aging, enzyme digestion, and banding. After these treatments, the chromosomes of the cells can be analyzed under a microscope to determine whether there are chromosomal abnormalities. This classic method has been used since its inception. [0003] In the past few decades, major breakthroughs have been made in many aspects of cytogenetics technology, such as cell synchronization culture technology, high-resolution chromosome technology and in situ amniotic fluid cell chromosome ana...
