- Which of the follow are correct statements about microscope handling and care? 1. Always use TWO HANDS to carry the microscope. 2. Only use LENS PAPER to clean the lenses. Never wipe back and forth, but simply make a gentle swipe across the lens. 3. A soft cloth should be used to clean the lenses. 4. Start and finish the day’s work at the LOWEST MAGNIFICATION. 5. Start and finish the day’s work at the HIGHEST MAGNIFICATION 6. Always BEGIN examining a specimen with a LOW POWER objective. 7. Always BEGIN examining a specimen with a HIGHEST POWER objective 8. On the compound microscope, NEVER use the coarse adjustment knob with the high power or oil objective. 9. On the compound microscope, ALWAYS use the coarse adjustment knob with the high power or oil objective. 10. Unplug the microscope by pulling on the plug, not the cord.1. Name the part of the microscope that you use to control the cone of light coming through the condenser. 2. What is the total magnification of your specimen you are viewing using the 40X lens?1.
