ETALON is a new series of excellent composite AFM probes.
In terms of quality-to-price ratio, it has no analogues in the world market.
 
High Accuracy High Resonance frequency noncontact AFM probes HA_NC series with stable and wear-resistant long lifetime W2C conductive coating.
 
The main advantages of W2C coated probes are:
  • 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.

 

Our investigations in december 2015 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.
