What organelles may be viewed with an electron and a light microscope?
1. You must master and strictly implement the operating procedures, and operate the microscope in accordance with strict procedures and instructions.
2. When picking up and delivering the microscope, be sure to hold the curved arm with one hand and the base with the other hand. The microscope cannot be tilted to prevent the eyepieces from slipping out of the upper end of the lens barrel. Handle with care when picking up and delivering the microscope.
3. When observing, the position of the microscope cannot be moved casually.
4. The optical part of the microscope can only be wiped with special lens-cleaning paper, and cannot be wiped with other objects, let alone touch the lens with fingers, so as not to stain the lens with sweat.
5. Keep the microscope dry and clean to avoid contamination by dust, water and chemical reagents.
6. When converting the objective lens, do not move the objective lens, only turn the converter.
7. Do not turn the focusing handwheel at will. When using the fine focus knob, use light force and slow rotation, and do not turn it hard when it cannot be turned.
8. Do not arbitrarily disassemble the parts on the microscope, and it is strictly forbidden to disassemble the objective lens at will, so as not to damage the converter screw, or the loose screw will make the low and high magnification objective lens out of focus when switching.
9. When using a high-magnification objective lens, do not use the coarse focus adjustment handwheel to adjust the focal length, so as not to move too far and damage the objective lens and glass slides.
10. Before returning after use, you must check whether the objective lens is stained with water or reagents. If there is, wipe it clean, and wipe the stage. Then put the microscope in the box and pay attention to lock the box.
