What should you use if you accidentally touch the lenses on a microscope?

Apply a small amount of lens cleaner (70% isopropyl alcohol) to one end of a piece of lens paper or clean swab. Holding the dry end, gently drag the moist end of the lens paper or swab across the front of the objective/ocular several times using a fresh section of moist lens paper each time.

What is one golden rule of using the microscope?

1. Always start off with the lowest magnification objective and work up to higher power one objective at a time. 2. Always observe the objective as it is rotated into place to ensure it doesn’t crash into the slide.

What part of a microscope makes the image clearer?

Condenser – These are lenses that are used to collect and focus light from the illuminator into the specimen. They are found under the stage next to the diaphragm of the microscope. They play a major role in ensuring clear sharp images are produced with a high magnification of 400X and above.

What should you never do with a microscope?

Always make sure the stage and lenses are clean before putting the microscope away. NEVER use anything but good quality lens tissue on any optical surface, with appropriate lens cleaner or distilled water; organic solvents may separate or damage the lens elements or coatings.

What objective is used for scanning the slides?

Scanning Objective Lens (4x) The name “scanning” objective lens comes from the fact that they provide observers with about enough magnification for a good overview of the slide, essentially a “scan” of the slide.

What 3 things do you do when you are finished using your microscope?

What liquids should you avoid using a microscope?

Disinfecting the frame: We recommend applying 70% ethanol since it effectively disinfects the microscope without damaging the frame. Remember avoid using organic solvents except ethanol that may damage plastic parts.

What is the first thing you should do once you have finished using your microscope? Switch to a lower magnification.

How do you keep the microscope in good condition?

How To Care for Your Microscope

1. Handle with care. If the microscope must be moved, carry it from the base and support arm, if picked up by stage or eyepiece holder it can become misaligned.
2. Keep covered. Every time you use or clean the microscope be sure to cover the kit to prevent dust and other contaminants from reaching the apparatus.
3. Store safely.

What is the proper way to carry a compound microscope and clean it?

Important general rules:

1. Always carry the microscope with 2 hands—place one hand on the microscope arm and the other hand under the microscope base.
2. Do not touch the objective lenses (i.e. the tips of the objectives).
3. Keep the objectives in the scan position and keep the stage low when adding or removing slides.

What objective should you set first when you want to focus the specimen?

Answer: When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power.
