Colloidal probe, AFM cantilever with round tip like a ball.

The new sQube® colloidal probe combines the well-known features of the proven Pyrex-Nitride probes series such as high application versatility and compatibility with most commercial SPMs with a reproducible sphere radius instead of a sharp tip. The excellent  radius and the minimized variation of diameter provide reproducible signals.

Pyrex-Nitride probes are designed for various imaging applications in contact or dynamic mode.

The so called "Colloidal Probe Technique", where single colloids are attached to AFM cantilevers for force measurements, opens the chance for a better understanding of fundamental interactions in a variety of fields.
Examples are adhesion phenomena, particle-surface-interactions, mechanical
properties, suspensions, hydrodynamics and boundary slip - to name just some out of an
increasing number of applications.

The Pyrex-Nitride probes have silicon nitride cantilevers with very low force constants.  The probe series features a support chip that is made of Pyrex. The cantilevers are stress compensated and have a 65 nm chromium / gold backside coating for high laser reflectivity.

    The probe offers unique features:

        - sphere material: polystyrol
        - excellent ball diameter A = 1,98 µm, B = 3,6 µm, or C = 6,1 µm (all +/- 5%)
          (Due to different masses the resonance frequency can differ.)
          Please choose A, B, or C by ordering!

Only one cantilever with sphere, please choose long or short!
