Silicon AFM probes, Tap 190

The Tap190 series silicon AFM probes with longer cantilever for tapping mode (Quesant AFM Systems). Made of monolithic silicon fitting most commercial AFM's, compatible with DI Nanoscope, PSI, JEOL, NT-MDT, Asylum, VEECO, WiTec and other commercial AFM's. 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.Technical Data: Tap190Rotated monolithic silicon probeSymmetric tip shapeAlignment groovesChip size 3.4 x 1.6 x 0.3mm
