Scout 70 Silicon AFM Probes, Pk 10
Scout Silicon AFM Probes
Reliable imaging every time. Rigorous inspection of every probe means each one performs as you expect. Pack of 10 general purpose AC mode silicon AFM probes, suitable for non-contact/soft tapping and force modulation modes in air, on softer samples.
Available:
Uncoated.
Aluminum backside coating.
Gold reflective backside coating.
Nominal 5 nm tip radius. Minimal variation in spring constant and resonant frequency.
