The FEI Tecnai TF-30 300KV TEM is configured for analysis of both hard and soft materials. The system is capable of cryotomography of biological specimens as well as TEM and tomography of hard materials. The system is equipped with high angle tomography, double-tilt and cryo holders and has the ability to perform energy filtered TEM (EFTEM) and high angle annular dark field (HAADF) analysis. Additionally, the TF-30 is equipped with the Gatan K2 direct electron detector which significantly improves both contrast and resolution for large and small molecules for cryo-electron microscopy.
The TF-30 is also equipped with the NanoMEGAS ASTAR TEM precession orientation imaging system enabling orientation-phase imaging with 1nm resolution. Additionally, the TF-30 has a Gatan K2 direct electron detector.
