How to Properly Maintain a Microscope

Microscopes require proper care in order to ensure many years of use. The following tips will help keep your microscope in great working condition. Please also refer to your microscope's user manual for more detailed instructions tailored for your specific microscope model.


  • Consistently use any dust covers and/or cases when the microscope is not in use. These accessories will prevent unwanted dust from settling on the microscope, making it easier to clean in the long run.

  • Store the microscope in a cool, dry environment to keep mold and other organisms at bay. It may even be helpful to place a packet of silica gel within the case/cover during storage to absorb any infiltrating moisture.


  • When transporting the microscope, always use one hand to hold the arm and the other to support the base.

  • The microscope should always be placed on a firm, flat surface. While microscopes appear sturdy, any sudden movements (e.g., toppling over) may cause parts to break or come loose.


  • Apply lens cleaning fluid with lens paper only to remove oil from the objectives (and anywhere else) after each use. Remember to use minimal pressure to avoid creating scratches on the lenses. Do NOT use anything other than lens paper for cleaning the lenses as coarser materials may cause damage.

  • If you notice that the immersion oil was not properly cleaned off the objective previously, use lens paper with distilled water and hold it against the objective for a few seconds to help dissolve the oil. If the oil still remains on the surface, wipe it off using lens paper with isopropyl alcohol (at least 90% purity).

  • Use an air blower to remove any dust on the microscope. The air blower is helpful in hard-to-reach places as well, such as inside the eyepieces.

Replacing Bulbs:

  • NEVER use bulbs that are of a higher wattage than recommended.

  • Allow the bulb to cool before replacing it.

  • Avoid touching the glass portion of the bulb with your fingers, and wipe off any dust prior to installation as oil and dust can reduce the life and quality of the bulb.
