Сканирующий туннельный микроскоп

Описание товара

The Nanosurf Easyscan 2 is a modular scanning probe microscopy system that offers flexibility at a great price: one controller, several scan head types, and various upgrade possibilities! Meant to resolve atomic structures at the surface of electrically conductive materials, this easy-to-use and compact, scanning tunnelling microscope is particularly suitable for training purposes. The complete system includes a probe for row-by-row scanning of sample surfaces with the measuring tip, vibration-absorbing pad, controller with computer interface, as well as graphite and gold samples.
