Stage clip is a spring piece mounted on the microscope stage for fixing the slide or the object to be observed.
What is the purpose of stage clips?
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. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope.
What is the stage plate used for microscope?
A stage plate is used with stereo microscopes. It uses a circular hole in the scope’s base to hold either a frosted glass plate for transmitted light from below or a dual-sided (black and white) plastic disk for improved contrast lighting with top (reflected) lighting of specimens.
How would you use stage clip when studying a specimen under the microscope?
Place the microscope slide on the stage (6) and fasten it with the stage clips. Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.

How do you observe a specimen under a microscope?
How to use a microscope
- Move the stage (the flat ledge the slide sits on) down to its lowest position.
- Place the glass slide onto the stage.
- Select the lowest power objective lens.
- Turn the coarse focus knob slowly until you are able to see the cells.
How should the microscope be set when placing a specimen on the stage?
Place the microscope slide with the specimen within the stage clips on the fixed stage. Move the slide to center the specimen over the opening in the stage directly over the light source.
How do you position the objectives and stage when storing a microscope?
Always place the 4X objective over the stage and be sure the stage is at its lowest position before putting the microscope away.
How should the microscope slide be placed on the stage?
Your microscope slide should be prepared by placing a coverslip or cover glass over the specimen. This will help protect the objective lenses if they touch the slide. Place the microscope slide on the stage and fasten it with the stage clips. You can push down on the back end of the stage clip to open it.
When observing a specimen in the microscope put the slide on the stage true or false?
Viewing Prepared Slides
Place a slide on the stage, label side up, with the coverslip centered. On LOW POWER ONLY, use the coarse focus knob to get the object into focus. If you cannot see anything, move the slide slightly while viewing and focusing. If nothing appears, reduce the light and repeat step 4.
When you put a slide on the stage where should you make sure the specimen is placed?
Place a slide on the stage. Center the specimen over the opening on the stage. Use the stage clips to hold the slide in place. 7.
When you first put a slide on the stage what magnification should you start with?
Start Low! Since the 4x objective lens has the least magnification, but a larger field of view, it allows for more of the specimen to be seen, as well as locating the part of the sample you wish to view. This in turn makes it easier to focus on the sample.
How do you prevent air bubbles in a microscope slide?
Preventing bubbles in slides
When ready to stain, take the sections out and put them in a vacuum again during the staining procedure (the BSA blocking step) for another 45 minutes. If there are still problems, move the vacuum step to the last wash before mounting, or add additional vacuum steps.
What is the difference between glass slide and coverslip?
The coverslip is placed over an object so it can be viewed with a microscope and placed on top of a glass slide that rests on the microscope itself, providing the physical support for the object. The glass coverslip holds the specimen in position using the weight of the slip or a wet mount created by surface tension.
When would you not use coverslip?
Coverslip thickness is less important when using objective lenses that have a numerical aperture (NA) of 0.4 or lower, which on most microscopes would only be lenses between 1x-10x. As magnification (2x or higher) and NA increases, the loss from having an incorrect thickness coverslip can become significant.
Can you use a microscope without slides?
In order for a compound microscope to work, light must be able to pass through the object you’re viewing. The best way to ensure this is by making a slide.
What is a depression slide used for?

What are concave slides used for?
Concave slides are suitable for specimens which would be too thick to be observed with regular slides. Water fleas, for example, are relatively thick and are easily crushed when sandwitched between slide and cover glass. Concave slides give them significantly more freedom for movement.
