High Efficiency Direct Drive TappingMode Fluid Probe Holder

Dimension microscopes can be equipped with an optional probe holder, the High-Efficiency Dimension Direct Drive Fluid Cantilever Holder (DTFML-DD-HE) that permits Fluid Imaging:

The fluid probe holder interchanges with the standard probe holder quickly and easily.

The fluid probe holder consists of a small Kel-F® assembly with a Pt-Ir wire clip for holding an AFM cantilever substrate and a glass window for the AFM laser. The glass provides a flat, beveled interface so that the AFM laser beam may pass into the fluid without being distorted by an unstable fluid surface. The DTFML-DD-HE includes a small piezo to directly drive the cantilever for improved ease of use in TappingMode. The four sockets located on the top of the fluid probe holder are used to attach the probe holder to the four pins at the end of the scanner tube.

Use the fluid probe holder in an open environment where the holder is dipped into a user-supplied fluid container (or into a drop of liquid on larger samples). See Sample Mounting for Fluid Applications for more information.

Viton Splash Shield

A Viton® splash shield is also provided with the fluid probe holder:

This splash shield is used to protect the Dimension scanner from coming into contact with the liquid. It is recommended that the splash shield be used with all wet samples. Splash shields wear over time and may need to be replaced.
