Precautions For Using A Microscope

1. Microscopes are precision instruments that must be used in accordance with operating procedures, with care and patience. Do not act too hastily or forcefully to prevent damage to components due to operational errors
2. Do not touch the optical glass part with your hands, and prevent violent collisions from damaging the components.
3. When observing, it is necessary to add a cover glass to prevent water from flowing onto the moving table, and to prevent acid, alkali, and other chemicals from coming into contact with the microscope. The microscope should not be exposed to sunlight.
When using the fine focus knob, if it cannot continue to rotate in the same direction and reaches the limit, it should not be twisted forcefully. Instead, it should be turned back in the opposite direction and the coarse focus knob should be turned, and then the fine focus knob should be used for fine adjustment.
5. If the eyepiece or objective lens is dirty, use specialized lens paper to wipe in a straight direction, and do not use fingers, handkerchiefs, or cotton cloth to wipe. If the eyepiece or objective lens is stained with oil, it can be wiped clean with a small amount of specialized lens paper dipped in xylene (or anhydrous ethanol and ether 1:1:1), and then wiped again with a clean lens paper.
