General information

NTEGRA Academia is a multifunctional device for teaching high school children and university students the basics of scanning probe microscopy, including the participation in research projects in the field of nanotechnology, physics, chemistry, biology, medicine etc. The device is capable of performing more than 40 measuring methods, what allows analyzing physical and chemical properties of the surface with high precision and resolution. It is possible to carry out experiments not only by conventional silicon cantilevers but also by tungsten wire which is chiper and easy to use in educational proposes.


Special device for the tangsten probes creation by the method of electrochemical etching which allows to sharpen tangten probes by students themselves.


Exchangeable scanner with capacitive sensors with a scan range in high voltage mode (X × Y × Z); 100х100х10 microns, in the low voltage mode (X × Y × Z); 3x3x2 microns Minimum scanning step: 2 nm.


Nova SPM software for high efficiency SPM control and image processing.


The new generation electronics provides operations in high-frequency (up to 5MHz) modes. This feature appears to be principal for the work with high-frequency AFM modes and using high-frequency cantilevers.*
