Hard coating which stays stable at applied high voltages and flowing currents at the contact point ‘tip-sample’ which cannot be received with standard metal coated probes (Fig.1-3);
High conductivity (close to metal conductivity);
Typical curvature radius less than 35nm;
W2C+ was modified by volume doping with anticorrosion elements thus providing long-term performance in high humidity conditions.
Experiments, carried out in december 2015 by engineers of NT-MDT Spectrum Instruments, approved great stability of W2C+ coated probes under high voltage, current and tip-sample pressure. AFM cantilevers showed to be able measure current of several mkA during the whole scan without any degradation. The same excellent performance continued after 100 I-V curves by the range +/- 10V.

How to get amount discount:
1. Add a box with 50 probes* to the Shopping Cart.
2. Change in the Shopping Cart the box quantity to the one you need.
3. Click the button 'Reculculate!' and get your discount.
* You can choose boxes with 50 probes of different ETALON series.
For example - for the order:
HA_FM/50 - 1 box
HA_NC/50 - 2 boxes
HA_HR/Pt/50 - 1 box
amount discount will be 25%, since 4 boxes with 50 chips are ordered.
** - for USA market there is another discount system. Please, contact us for further information.
