Our SEM is delivered with a starter kit that includes most of the basic supplies you will need.  However, each application has its own specific requirements to achieve the most optimal sample preparation and presentation of the sample with the SEM.  That said, we are happy to recommend supplies to you that would be useful for your application based on our extensive background in sample prep.  We feel like the best range for SEM supplies is available from Rave Scientific.  We have listed a number of Electron Microscopy supply providers on our LINKS page.
