Detailed explanation-1: -Using a pipette, place a drop of water on the specimen. Then place on edge of the cover slip over the sample and carefully lower the cover slip into place using a toothpick or equivalent.
Detailed explanation-2: -A mounted needle can be used to hold the specimen in place as the coverslip is lowered. It is important that no air bubbles are trapped underneath. Most cells are colourless. Stains are used to add contrast.
Detailed explanation-3: -It protects the microscope and prevents the slide from drying out when it’s being examined. The coverslip is lowered gently onto the specimen using a mounted needle . It is important that no air bubbles are trapped underneath.
Detailed explanation-4: -The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus.
Detailed explanation-5: -Stage clips hold the slides in place. Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power.
