Which of the following statements is not true regarding the use of a microscope?

• A. Carry with two hands
• B. Store on the low power objective
• C. Clean all lenses with lens paper
• D. Focus on the high power

Answer: (D)

Focusing on high power without proper technique can lead to damaging the slide or the objective lens of the microscope. When using a microscope, it is essential to start focusing with the lowest power objective first. This allows for easier location of the specimen and provides a clear view before switching to higher power objectives. Once the specimen is in focus on low power, only then should one move to a higher power to view more detail.

Proper usage includes carrying the microscope with two hands for stability and safety, storing it with the low power objective in place to protect the lenses, and cleaning lenses carefully with lens paper to avoid scratches and damage. These practices help ensure the longevity and functionality of the microscope.
