Short description: The H-7650 is Hitachi high contrast and resolution transmission electron microscope used specifically for applications in research fields such as biology, medicine, polymers, and other advanced materials. Allowing high contrast low dose image observation, the H-7650 is optimized to reduce specimen damage associated with typical electron microscopy observation. A high sensitivity digital camera has been integrated with the microscope and images can be recorded, stored, filed, or transferred to anyone in the world efficiently and effortlessly.
Keywords: TEM, high contrast, high resolution, nanomaterials, material science, biology, medicine, polymers, carbon nanotube, graphene
Access policy and costs
Services provided: The TEM electron microscopy laboratory offers quality imaging services for both the academic and non-academic environment. The software program of the device offers a tool in the processing of data related to the shape, size, and distribution of the particles.
The expenses regarding the measurements are calculated according to the expenses necessary for the preparation of the samples. Access to the services offered is based on prior scheduling depending on the number of samples and their complexity.
