It colors red for blood cells, cytoplasm and cell membranes. A vaginal wet mount (sometimes called a vaginal smear) is a test to find the cause of vaginitis, or inflammation of the vagina and the area around the vagina (vulva). Place a drop or two of suspension on a clean slide, and turn the coverslip Some organisms (like Paramecium) need more space than what forms between a coverslip and a flat slide. For a compound microscope, the sample needs to be very thin and as flat as possible. Microscope slides and slide covers are small and delicate. You will be using two main types of slides, 1) the common flat glass slide, and 2) the depression or well slides.

Less frequent characteristics include rectangular shapes, alternative materials such as quartz and certain types of plastic, etched lines or grids and additional thicknesses. Your coverslip is now sealed with nail polish. To prepare a wet mount you need a few materials. Obtain a clean microscope slide and cover slip. Secure the coverslip with tape, clips, or a slide holder. Edit the footage using the computer and software. Without the cover in place, surface tension would cause the droplet to bunch up in a dome. 5 Why do you need to prepare a wet mount?

Microscopes are designed to use these slides, and won't work if the slide isn't prepared properly. Section mounts are suitable for useful for a wide variety of samples such as fruit, vegetables and other solids that can be cut into small slices. This will reduce the risk of air bubble formation when you position the cover slip. The liquid used depends on the type of cell being viewed.

Eosin's most important medical uses are in blood and bone-marrow testing, including the PAP smear. Examine the specimen using the microscope, adjusting the focus and magnification as needed. Emulsify the specimen in a drop of 20% KOH on a glass slide with the help of inoculating loop. The cover breaks this tension, flattening the sample and allowing very close inspection with minimal focusing. If viewing a sample not already in the liquid, use tweezers to position the specimen within the drop.
