Glass slides are glass or quartz slides used to place samples when observing things with a microscope. When making samples, cells or tissue sections are placed on the glass slides, and the cover slides are placed on them for observation. A sheet of glass like material used to produce phase differences.
The cover glass is a thin and flat glass sheet of transparent material. Objects are usually placed between the cover glass and the thicker microscope slide. The microscope slide is placed on the platform or slider frame of the microscope and provides physical support for objects and sliding. The main function of the cover glass is to keep the solid sample flattened, and the liquid sample can form a uniform thickness, which is convenient for observation under the microscope.
2. Different shapes: the glass slide is rectangular, 76mm*26mm in size, relatively thick; The cover glass is square, with the size of 10mm*10mm or 20mm*20mm, which is relatively thin.
3. Different positions:
The slide below is the carrier of the observed substance;
The cover glass is usually placed on the glass slide with the observation sample material, mainly for the convenience of observation and to avoid the contact between the liquid and the objective lens, so as to avoid polluting the objective lens. It can also effectively prevent the substances in the air above from polluting the observed substances.
4. Different cleaning methods: cover glasses are generally disposable and do not need to be cleaned. Glass slides are usually cleaned with water or alcohol. If there are high sanitary requirements for utensils, ultrasonic washing machines can be used for cleaning.
Seeing this, it is not difficult for us to find that there is still a great difference between the slide and the cover glass. We must distinguish them when using them and try not to make mistakes
