What to do if the objective touches the cover slip on my AmScope 120 Microscope?

  If the objective on your AmScope Microscope touches the cover slip, replace the cover slip with the appropriate 0.17mm thickness slip, as the cover slip may not be standard-sized. Also, be careful to avoid contact between the objective and the slide when the limit stop is up (unless using the 100x objective with oil). To reengage, focus the sample, then lock the limit stop into place at the stage height to set the max height at a safe but usable distance.

  If you're having trouble moving the slide smoothly on your AmScope Microscope, first, adjust the slide to use the stage clips and secure the sample correctly. If the issue persists, tighten the mechanical stage screws to better secure the stage.

  If you observe obstructions in the field of view of your AmScope Microscope, check the specimen slide for stains, dust, or dirt. Clean the slide, or use a new specimen if the sample is destroyed. Also, check the lens for stains, dust, or dirt and clean the lens.

  If one side of the field of view is dark, or the image moves while focusing on your AmScope Microscope, make sure the specimen slide is secured to the stage with clips. Additionally, ensure the nosepiece is correctly positioned by turning it until it clicks into place.

What to do if my AmScope 120 does not light up?

  If your AmScope Microscope does not light up, first, ensure that it is properly plugged into the wall socket. If it is plugged in, but still doesn't light up, the bulb may have burned out. However, the unit’s LED bulb should not burn out, so the bulb is likely not the issue. Please contact customer service for warranty repair information. Also, check the fuse; if it has burned out, replace it with the fuse on the bottom of the microscope.

  If one side of the field of view is darker on your AmScope Microscope, first, make sure the nosepiece is correctly aligned by turning it until it clicks into place.
