FEI Tecnai Spirit Bio-Twin Transmission Electron Microscope


The Tecnai G2 Spirit BioTWIN, a 20-120 kV / LaB6 Transmission Electron Microscope, is a general-purpose instrument that is specifically suited for low contrast samples.  It enables the user to explore the native state of low-contrast, beam-sensitive biological specimens, or other soft materials like polymers.  Samples can be unstained or stained.  The lens design guarantees maximum contrast.  Our Tecnai Spirit is cryo-capable.
