Description
Technical Field
The invention relates to the technical field of experimental equipment, in particular to a glue-free cover glass and a pasting method thereof.
Background
A coverslip is a thin, flat piece of glass of transparent material, typically square or rectangular, approximately 20 mm (4/5 inches) wide and a fraction of a mm thick, that is placed on an object to be viewed with a microscope. The object is typically placed between a cover slip and a slightly thicker microscope slide, which rests on the stage or slide holder of the microscope and provides physical support for the object and slide. The existing method for covering a glass slide with a cover glass is that an operator firstly sprays glue on the cover glass and then covers the glass slide, but less glue is sprayed, bubbles can be generated when the cover glass and the glass slide are closed, or more glue is sprayed, the glue can overflow, and the experiment staff is difficult to observe and study.
Disclosure of Invention
In view of the current situation of the prior art, the present invention provides a glue-free cover glass and a pasting method thereof, so as to solve the above technical problems.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a glue-free cover glass is characterized in that: the glass cover glass comprises a cover glass body, wherein a coating which is soluble in an organic solvent is arranged on one side surface of the cover glass body, and the refractive index and the light transmittance of the coating are the same as those of glass.
By adopting the technical scheme, the coating is directly arranged on the cover glass body in advance, when the glass slide is closed, one surface of the cover glass body with the coating faces the glass slide to be covered, the glue spraying process is reduced, bubbles are not easy to generate, the storage is easy, and the observation is easy because the refractive index and the light transmittance of the coating are close to those of the glass.
It is further provided that an area of the coating is equal to a side area of the cover glass body.
Through adopting above-mentioned technical scheme, the coating area equals with the cover glass area, can reduce the bubble, can make more firm that cover glass body and slide glue again.
A method for sticking a glue-free cover glass comprises the following steps:
step 1, cleaning: cleaning the cover glass body;
step 2, spraying a coating: uniformly spraying coating liquid on one side surface of the cover glass body;
and 3, drying or airing: drying or airing the cover glass body sprayed with the coating liquid;
and 4, spraying an organic solvent: soaking the glass slide in an organic solvent and taking out the glass slide, or spraying a layer of organic solvent on the surface of the glass slide;
step 5, pasting: covering one side of the dried cover glass body, which faces the glass slide and is provided with the organic solvent, with the coating
The coating liquid further comprises resin, and the organic solvent is xylene or other solvent capable of dissolving the resin.
By adopting the technical scheme, the resin is dissolved in the organic solvent, has viscosity, can enable the cover glass body to be directly pasted on the glass slide, does not need to spray glue on the cover glass body, has simple manufacturing process and method, effectively prevents bubbles and is easy to store and observe.
Compared with the prior art, the invention has the advantages that:
the invention provides a glue-free cover glass and a pasting method thereof, the glue-free cover glass is obtained by spraying a coating on a cover glass body, and resin is dissolved in an organic solvent and has viscosity, so that the glue-free cover glass and a glass slide sprayed with the organic solvent are combined together.
Drawings
FIG. 1 is a schematic view of the overall structure of the glue-free cover glass of the present invention;
FIG. 2 is a flow chart of the glue-free coverslip application method of the present invention.
In the figure: 1. a cover glass body; 2. and (4) coating.
