SPARK 70 Pt - Conductive AFM probe

£350.00

Enjoy reliable imaging every time using our pack of 10 conductive AFM probes with platinum coating on both sides, suitable for electrical characterisation in both contact mode and AC modes (non-contact/soft-tapping).

40 nm platinum coating with a 5nm titanium adhesion layer on both sides of the probe and a tip radius of less than 30 nm.

We also offer SEM images of each individual tip.

Spring constant: 2 N/m

Resonant frequency: 70 kHz

High quality imaging every time…

The probes themselves have been impeccable; they were affordable, high quality and the data they have produced have convinced us to make NuNano our regular supplier.” — Steve Gibney, University of Nottingham

“The tips do a much better job than our current provider. Feedback on the rather rough surfaces is much more responsive, presumably due to the higher resonance frequency. We are, in fact, quite satisfied with your tips.” - Pascal Schweizer, Justus Liebig University Giessen
