Background

The slide glass is a glass or quartz plate for holding things when observing them with a microscope, and when a specimen is produced, a cell or tissue section is placed on the slide glass, and a cover glass is placed thereon for observation. In modern medicine, glass slides are widely used in the optical detection of biological specimens.

The glass slide is a glass slide for placing a biological specimen in an experiment, is rectangular, has the size of 76 x 26mm and the thickness of about 1.5mm, and has the characteristic of good light transmittance. Slides are typically used with coverslips. The cover glass is covered on the glass slide added with the biological specimen, so that the liquid is prevented from contacting with the objective lens of the microscope, and the objective lens of the microscope is prevented from being polluted. The cover slip is generally square, 10 x 10 mm or 20 x 20mm in size, about 0.5mm in thickness, and preferably transparent.

The usage of the slide is as follows.

1. The smear method is a slide making method in which a material is uniformly coated on a glass slide.

The smear material includes unicellular organism, microalgae, blood, bacteria culture solution, loose tissues of animals and plants, spermary, anther, etc.

Care should be taken when smearing (1) the slide must be cleaned. (2) The slide is held flat. (3) The coating must be uniform. The smearing liquid drops are smeared evenly by a dissecting knife or a toothpick and the like on the right side of the middle of the glass slide. (4) The coating is thin. The other glass slide is used as a push piece, and the surface of the glass slide on which the smearing liquid is dripped (the included angle of the two glass slides is 30-45 degrees) is slightly pushed from right to left to be smeared into a uniform thin layer. (5) And (4) fixing. If necessary, the solid can be fixed by chemical fixative or drying method (bacteria). (6) And (6) dyeing. The bacteria are treated with methylene blue, the blood is treated with a morningella stain, and iodine is sometimes used. The dyeing liquid is used for covering the whole coating surface. (7) And (5) flushing. Sucking with absorbent paper or oven drying. (8) And (6) sealing the sheet. Canada gum seals were used for long term storage.

2. The tabletting method is a tabletting method for placing biological materials between a glass slide and a cover glass and applying certain pressure to scatter tissue cells.

3. The mounting method is a method for integrally sealing and fixing biological materials to prepare a glass slide specimen, and temporary or permanent mounting can be prepared by the method.

The sheet material comprises tiny organisms such as Chlamydomonas, spirogyra, amoeba, and nematode, Hydra, plant leaf epidermis, insect wing, foot, and mouth organ, and human oral epithelial cell.

The slide glass is held by hand, and (1) the slide glass is held flat or placed on a platform. The water amount is proper when the water is dripped, and the water is just covered by a cover glass. (2) The material should be spread out with a dissecting needle or forceps so that it does not overlap, lying flat on the same plane. (3) When putting the cover glass, the cover glass is slowly covered on the water drop from one side to prevent air bubbles. (4) During staining, a drop of stain was dropped on one side of the cover glass, and the other side was aspirated with absorbent paper to uniformly stain the specimen under the cover glass. After coloring, a drop of clear water was added in the same manner, and the staining solution was aspirated and observed under a microscope.

4. The section is a method of preparing a slide specimen from a slice cut from a living body.

Depending on the requirements, the tissue blocks may be sliced by hand with a razor blade or by embedding the tissue blocks in paraffin or collodion or by freezing at low temperatures and slicing with a microtome. And cutting into 5-10 micron slices for observation by an optical microscope. The ultrathin section cut by embedding the tissue block with epoxy resin or methacrylic acid is 20-50 nanometers thick and is specially used for observation under an electron microscope. The general teaching section of root tip and stem is commonly called paraffin section.

The glass slide can be recycled for multiple times, so that after each use, the glass slide needs to be cleaned by adding clear water or alcohol with a cleaning agent, and then is dried by hot air and stored on the glass slide rack uniformly so as to be reused next time.

In some laboratory slide treatments, slides are inserted vertically into slide holders (shown in fig. 1), the entire slide holder is placed in a bath with dye for staining, and the slide holder is removed after staining, which when the stained slide is removed from the slide holder, can contaminate gloves by direct manual manipulation and bring color into the next slide, affecting the accuracy of subsequent slide manipulation and experimental values.

Therefore, in the prior art, when the slide glass is stored or taken, a special tool for clamping the slide glass is not used, and the slide glass is directly taken by fingers. When a finger touches the slide, the finger easily leaves a fingerprint on the slide or contaminates the slide, which affects the next observation and use of the slide. Therefore, the utility model designs a special clamping tool for glass slides, which solves the technical problem.
