SENSE 20 - Silicon nitride AFM probe
SENSE 20 - Silicon nitride AFM probe
Benefit from high quality imaging with our pack of 10 general purpose silicon nitride AFM probes, suitable for imaging soft samples using contact or AC mode in either air or liquid. They feature a sharp silicon tip integrated onto a silicon nitride cantilever with a gold reflective backside coating.
Spring constant: 0.07 N/m
Resonant frequency: 20 kHz
