How we will help you

At MSL we will maximize your chances of success by:

  • Consulting with you about your project
  • Preparing your samples for electron microscopy
  • Taking high quality images of your samples using our transmission and/or scanning electron microscopes

Please contact us as early as possible in your project. We support projects that require transmission electron microscopy (TEM) and scanning electron microscopy (SEM).


Sample preparation services

Consult our flowchart below for what to expect:
