Hi there,

We would like to use our Dimension Edge for investigating the mechanical properties of films in membranes.

Could you please tell me what is the maximum force that can be safely applied through the scan head?

(this is needed to calculate the most convenient geometry of the membranes)


Thank you very much for your help.

Hi Zagari,


The stiffest probes we manufacture are around 200N/m and on the Edge AFM detector arrangement these have a deflection sensitivity of around 70nm/V. I have in the past used these kind of probes with up to 10V deflection for indentation experiments. This puts you into the 150uN range. I would suggest that is a good maximum force limit.
