BioLever

The "B" cantilever on the Biolever is one of the softest cantilevers commercially available today.  These probes have a visible, V-shaped tip that is stable and unique to only this product.  Geometrically, the tip is a hollow pyramid sliced in half vertically with a sharpened apex.  Very small and very soft cantilevers like these are excellent for force curve measurements.  This silicon nitride probe has two different rectangular cantilevers with unique resonant frequencies and force constants.
