Contact Mode AFM/LFM, Tapping Mode AFM, MFM and STM (Routine operation) Other options like operations with Fluid Cell, C-AFM, Nano Indentation etc., may be possible on special cases with limited access.
For SPM samples with highly polished surfaces, single crystals, thin films can be accommodated.
Sample Size: Typical 5mmx5mm.
Thickness: Typical 1-2mm.
Both sides should be as flat as possible.
For STM, samples should be conducting to a nominal extent. So also for Conductive AFM
