Bruker's Sharp Nitride Lever (SNL) probes are the industry standard for high-performance imaging with TappingMode in fluid. These probes marry the sharpness of a Silicon tip with the low spring constant and high sensitivity of a Silicon Nitride cantilever, for an unprecedented level of resolution and force control on just about any sample, in any medium. The unique design of each SNL probe includes four cantilevers with varying degrees of force constants and resonant frequencies, providing enough versatility to cover a large majority of sample types.
The SNL cantilever layout is identical to that of the other NP products, with "A" and "B" cantilevers on one side of the probe, and "C" and "D" cantilevers on the other side of the probe. See the cantilever orientation diagram here.
All cantilevers on the SNL probes have <2 degrees of cantilever bend, making them ideal for use on all Bruker and non-Bruker AFMs.
