Description

Improved chromosome preparation platform Technical Field The utility model relates to the field of chromosome preparation, in particular to an improved chromosome preparation platform. Background Currently, the edge of the substrate (hereinafter referred to as a "slide substrate") is about 1cm higher than the inside of the recess, so that the slide glass forms an inclination angle of 10 ° -15 ° with the horizontal plane. After the liquid sample is dripped on the high end of the glass slide, the liquid sample can flow along the inclined plane to realize even distribution of chromosomes. The method comprises the following four defects that 1, chromosome dispersion quality is unstable, the volatilization speed of a fixing solution (mixed solution of methanol and acetic acid in a volume ratio of 3:1) directly influences chromosome dispersion effect, airflow in an ultra-clean workbench is accelerated to volatilize, so that dispersion quality is reduced, 2, sample dripping precision is low, samples are required to be dripped to a glass slide from a height of about 15 cm, accurate positioning of a target area is difficult, 3, potential safety hazards exist in open design, volatile toxic gas is easy to be inhaled by operators, 4, the glass slide is inconvenient to fix, a standardized clamping groove is lacked, time-consuming to install and easy to deviate, and an improved chromosome preparation platform is provided for the problems. Disclosure of utility model The utility model aims to solve the technical problems that the existing device comprises the following four defects in use 1. The chromosome dispersion quality is unstable, the volatilization speed of a fixing solution (a mixed solution of methanol and acetic acid in a volume ratio of 3:1) directly influences the chromosome dispersion effect, the dispersion quality is reduced due to the fact that air flow in an ultra-clean workbench is accelerated to volatilize, 2. The sample dripping precision is low, samples are required to be dripped from about 15 cm to a glass slide in a height mode, a target area is difficult to accurately position, 3. The open design has potential safety hazards that volatile toxic gas is easy to inhale by operators, 4. The glass slide is inconvenient to fix, and the problems of time consumption and easy deviation in installation due to lack of standardized clamping grooves are solved.
