SCOUT 70 HAR - Silicon AFM probe
SCOUT 70 HAR - Silicon AFM probe
Get high quality images every time with our pack of 10 general purpose AC mode silicon AFM probes with a high aspect ratio tip. Ideal for deep trench imaging with non-contact/soft tapping and force modulation modes in air, on softer samples. Available uncoated or with an aluminium or gold reflective backside coating. We also offer SEM images of each individual tip.
Spring constant: 2 N/m
Resonant frequency: 70 kHz
High aspect ratio: Cone angle of < 15 ° over the final 1 μm of the tip

Reliable probes that save you time…
“The SCOUT probes give more reliable high resolution than other suppliers, which often have a dud or two from every box, hence why I recommend them.” - Dr James Thomas, University of Oxford, UK
“It was much easier to set up “good” imaging parameters with these tips compared to tips from other suppliers. I will definitely recommend these.” - Fouzia Bano, University of Leeds
