Microscopic sample preparation device and cell phenotype control device

Abstract

The invention provides a microscopic sample preparation device and a cell phenotype control device. The microscopic sample preparation device comprises: a forming plate which is provided with a plurality of forming holes penetrating through two opposite surfaces of the forming plate and is used for forming a plurality of solid culture media; a sample cell plate provided with a plurality of sample holes penetrating through two opposite surfaces of the sample cell plate, wherein the sample holes are used for accommodating a plurality of solid culture media; a cover glass placed on one surface of the sample cell plate; and a pressing plate provided with a plurality of pressing columns and used for pressing the plurality of solid culture media in the plurality of forming holes into the plurality of sample holes and pressing the plurality of solid culture media on the cover glass. The plurality of solid culture media can be prepared at a time, tabletting operation of a plurality of samples can be completed at a time, time is saved, the experiment efficiency is effectively improved, operation is easy, convenient and rapid, the situation of misoperation is not prone to occurring, and cover glass is not prone to being crushed.

Description

technical field [0001] The invention relates to the technical field of micro-experiments, in particular to a micro-sample preparation device and a cell phenotype control device. Background technique [0002] In the process of biological or medical experiments, in order to better observe individual bacteria or cells on the microscope, the following sample preparation process is often used: drop the bacteria / cell suspension on the cut solid medium (such as agar block); etc. After the agar surface is slightly dry, press the side of the agar block dripping the suspension onto a glass coverslip; then place it on an inverted microscope to observe bacteria or cells. The process described above may be referred to as the tableting process. [0003] The above experimental process requires manual operations such as cutting the agar block, dropping the bacteria / cell suspension on the agar block, pressing the agar block dripped with the suspension on the glass cover slip, etc. The exper...

AI Technical Summary

Problems solved by technology

[0003] The above experimental process requires manual operations such as cutting the agar block, dropping the bacteria / cell suspension on the agar block, and pressing the agar block dripped with the suspension on the glass cover slip. The experimenter must operate carefully to get better results. For example, the glass coverslip may be crushed. In addition, when a large number of experimental samples are pressed, it needs to be operated one by one. The whole experimental process is time-consuming, inefficient, and consumes a lot of time and energy of the experimenter. Operational errors occur that seriously affect the progress of scientific research or medical diagnosis
