Correct operation of biological slides is particularly important

Biological slides should be cleaned before use. After rinsing with clean water, gently wipe with gauze or other soft cloth. When making the temporary slide, the correct operation of the cover slide is to gently clamp the cover slide with tweezers and cover it slowly at a 45 ° angle, so that one side of it contacts the liquid drops on the slide first, and then it is leveled slowly. In fact, the purpose of this is to prevent bubbles under the cover glass. Remember not to let air flow between the observation object and the cover glass. This will affect the observation effect.

Then, after we use biological slides, we should also clean and dry them in time for next use. In fact, slides can be reused. Although they are cheap, they are not disposable. If we usually use them, we can wash them with the detergent we always have at home.

If you are a friend with high requirements, you can use an ultrasonic washing machine for cleaning. If you don't have an ultrasonic washing machine, you need to be very clean. After cleaning with ordinary cleaning procedures, soak it in chromic acid detergent for one night, and then clean it with distilled water. This is also a very practical, convenient and effective method.

Although the body size is small, the effect is not small. The main function of covering Bioglass is to make the observed objects form a film, which is easy to transmit light, easy to observe, and make the thickness of liquid samples uniform. The purpose is to make the high-resolution microscope focus better, easy to use capillarity, and make various reagents (dyes, acids, salt solutions, etc.) form a gradient. At the same time, the glass cover can also keep the observation specimen fixed and flat, so as to protect the specimen from dust and accidental contact. At the same time, it also avoids polluting the objective lens when it accidentally touches the specimen when the objective lens descends. In an oil or water immersion microscope, the cover slides to prevent the immersion solution from contacting the sample.

The biological slide can be pasted on the slider to seal the sample and delay the dehydration and oxidation of the sample. Microbial and cell cultures can be grown directly on cover slides, and samples can be mounted on slides for a long time instead of loading slides.

It is very important for high resolution microscope to cover the thickness of biological slide. No. 1.5 cover glass (0.17mm thick) adopts a typical biological microscope design, and the mounting seat is used to fix the glass cover on the sliding cover. Using cover glasses that deviate from the expected thickness will reduce spherical aberration, resolution and image intensity. Professional targets can be used to image specimens without cover glass, and can also be used to allow the user to adapt to changing the thickness of the cover glass.
