TESPA

Product Description:

***Note: The final day for ordering the TESPA probe will be January 31st, 2015, after which point, it will become obsolete and replaced by the new model TESPA-V2.  Read the TESPA obsolescence notification letter here and contact your local Bruker representative if you have any questions or concerns.

Bruker's premier line of etched silicon probes are the industry standardfor imaging in TappingMode and non-contact mode in air.  Tightspecification control, unrivaled sensitivity, and dependably sharp tipsall contribute to producing consistently accurate, high-resolutionimages. 

This AFM probe is unmounted for use on any AFM and is also available without Aluminum reflex coating as model TESP. 

For a probe with similar specifications at a lower cost try the NCHV-A probe, part of Bruker's new VALUE line!
