A microscope allows you to observe objects which are too small to be seen with the naked eye. To maximize your laboratory experience in the study of cells and tissues you must master the use of a microscope.
Here are a few rules which will protect the microscopes from damage:
1. ALWAYS USE TWO HANDS TO CARRY THE MICROSCOPE. ONE HAND SHOULD BE ON THE BASE AND ONE HAND ON THE ARM (SEE "PARTS OF THE MICROSCOPE" BELOW).
2. NEVER TOUCH THE LENSES OF THE MICROSCOPE WITH ANYTHING EXCEPT THE LENS PAPER PROVIDED BY YOUR TEACHER.
3. TURN OFF THE LIGHT AND RETURN THE LENSES TO THE LOWEST POWER POSITION BEFORE RETURNING THE MICROSCOPE TO THE STORAGE AREA.
Observing these rules will protect the microscopes from damage and insure that they will be available for your use throughout the semester.
