The Tap190 series silicon AFM probes with longer cantilever for tapping mode (Quesant AFM Systems). Made of monolithic silicon fitting most commercial AFMs, compatible with DI Nanoscope, PSI, JEOL, NT-MDT, Asylum, VEECO, WiTec and other commercial AFMs. The AFM cantilever and tip are micromachined with excellent uniformity and a sharp tip radius for high quality imaging. They feature alignment grooves for correct holding and calibration of probes (alignment grooves do not affect the AFM probe in systems that do not require this feature).

See images for AFM probes coatings and application information.
