Punte per noncontatto della serie NSG11 con rivestimento conduttivo in Pt, ogni chip ha due cantilever, frequenza di risonanza 190-325kHz, 115-190kHz; costante di forza 5,5-22,5N/m, 2,5-10N/m.

 

NSG11/Pt series specification 

  • Standard chip size: 1.6x3.6x0.4 mm.
  • Compatible with the most commercial SPM devices.
  • High reflective Au coating (reflective property is 3 times better in comparison with uncoated cantilevers).
  • Tip side of the chip is coated by Pt conductive coating.
  • Thickness of Pt film is 20-30nm.
  • Typical curvature radius of a tip: 35 nm.
  • Tip height: 10 - 15 µm.
  • Each chip has two RECTANGULAR springs.
  • Recommended for noncontact/semicontact modes.
  • Packaged in GelPak® boxes.

GelPak® is a registered trade mark of Vichem Corporation.
