Dunk and Scan Probe Holder

 

Model: DS-TTAFM

The TT-AFM Dunk and Scan Probe Holder is an open liquid cell for scanning samples submerged in liquids.  The Dunk and Scan can directly replace the TT-AFM probe holder or the NP/SA/or LS-AFM probe holder.

Diagram of dunk and scan

In this design, the laser passes through a glass window and a small amount of liquid, and is then reflected off the cantilever. After reflecting off the cantilever, the light passes through the liquid and then through the glass window. For scanning in liquids, the Dunk and Scan Probe Holder is typically much simpler to use than an environmental cell.

A major advantage to this design is that air bubbles cannot easily form on the glass window's surface. Additionally, the Dunk and Scan Probe Holder is a direct replacement for the standard probe holder used in the TT-AFM.
