Bio-Medical 120kV TEM HT7700

The revolutionary new-style HT7700 120 kV bio-medical TEM from Hitachi is set to make life much easier for microscopists. HT7700 features 100% integration of all functions into the graphical user interface. The HT7700 is the latest in Hitachi’s popular H-7000 series of TEMs optimized for high contrast imaging at low electron doses, of which over 800 units have been shipped world-wide.

Besides the established slow-scan image acquisition camera, the HT7700 features a unique, high sensitivity real-time digital CCD camera which enables all microscope operations to be performed through the graphical user interface - including setup, alignment, image adjustment and sample search with a sensitivity higher than that of a human eye observing a fluorescence screen. Practical operation is performed on a console separate from the electron column, similar to SEM – reducing the installation space required and making the instrument easier and more intuitive to use by ensuring that all functions are available in one location.

Typical bio-medial or pathological work deals with large-area yet low-contrast samples, in which the small feature of interest is not easy to find. Traditional site-of-interest search has been performed by viewing a fluoresence screen with a binocular in a dark room. Besides operator fatigue, sensitive samples tend to suffer beam radiation damage as higher probe currents have been required in order to generate sufficient contrast on the fluoresence screen for the operator's eyes.

HT7700 changes that completely!
