Used level sensors

Consider the type of microscope (optical, electron, digital), its magnification power, resolution, and the specific needs of your application. Also, check for the condition of lenses and the overall build quality.

Use a trusted shipping service that specializes in delicate instruments. Ensure the microscope is well-packaged with adequate padding and secured to prevent movement during transit.

Regularly clean the lenses and eyepieces with appropriate cleaning solutions. Check and calibrate the focus and alignment. Store the microscope in a dust-free environment when not in use. Refer to the manufacturer's manual for specific maintenance guidelines.
