SABRE 300 - Silicon AFM probe
SABRE 300 - Silicon AFM probe
High quality silicon AFM probes for non-contact/tapping modes in air with the tip positioned at the very end of the cantilever. Available uncoated or with an aluminium or gold reflective backside coating. We also offer SEM images of each individual tip.
Spring constant: 32 N/m
Resonant frequency: 300 kHz
