Product Description:

PFTUNA probes combine the low spring constant and high sensitivity of a nitride cantilever with a sharp, electrically conductive tip.  When used with Brukers exclusive PeakForce TUNA mode, they enable an unprecedented level of high resolution electrical characterization on fragile samples.
