Usage of microscope slide: It is mainly used to carry cells or tissue sections that need to be observed under a microscope. It is a thin slice of glass-like material used to generate phase difference in optics. Protect the objective lens from contamination. Adjusting the objective lens may inevitably cause the objective lens to be too close to the object to be observed so as to contact the objective lens, which will contaminate the objective lens. Continue to adjust the lens, the distance is suitable and can't see clearly, I have to re-clean the lens before it can be used. With the cover sheet, the lens will not be polluted, as long as you continue to adjust the objective lens away from the object, you can observe normally when you reach a suitable distance. It is best to first adjust the objective lens to the closest place to the object, and then observe the microscope, while adjusting the objective lens gradually away from the object to find the clearest image. This will neither contaminate the mirror nor damage the Microscope Cover. microscope slide have a constant positive charge, which always holds tissue sections or cells firmly on the slide surface. Microscope Slides have demonstrated excellent performance in acid-base antigen retrieval solutions. Throughout the entire process of immunohistochemical staining, there is a huge risk of tissue exfoliation or cell loss due to continuous immersion and frequent washing, especially antigen retrieval and immediate washout after heating. All microscope slides have a coloured writing surface at one end, and the coloured coated writing surface has a depth of 20 mm.
