areas of interest and mark them Respect other’s time in the lab Respect my time in the lab

Not all SEM images are sharp and clear. If you just need basic information you can usually obtain that from a blurred image.

Publication images need more care and might require improper sample prep for best results (i.e. over coating)

Optical microscopes are available on a first come first serve basis

If you need instruction please let lab personnel know before you use them so as not to interrupt SEM sessions

Request Sheet

To be filled out only by those that have lab personnel operate the S4700

The more information available the better the analysis.

Include previous work, operators do not remember each request.

Lab Etiquette

No food or drink on the SEM console. Please do not interrupt a person while

operating the scope. Be aware of how long it will take you to

examine your samples. Clean up your sample prep.
