BioUnit 1: Room 103
The HT7800 RuliTEM is a 120 kV transmission electron microscope (TEM) with multiple lens configurations offering high contrast and high resolution. It has a dual-mode objective lens supporting easy observation under low magnification, wide-field high contrast, and high resolution. Operation under normal room light allows the user to effectively operate the instrument. Advanced stage navigation allows whole grid searching and efficient image acquisition.
Capabilities:
- Electron Gun: Tungsten or Lab6 Filaments
- Accelerating Voltage: 20-120kV
- Resolution(Lattice): .204nm
- Maximum Stage Tilt: ±70°
- TVIPS TemCam-F216 : 4 megapixel, 32 × 32 mm² with active pixel sensors
Applications:
- High-resolution biological imaging: ultrastructure of cells, tissues, organelles, viruses, and bacteria.
- Negative stain imaging: macromolecules, viruses, protein complexes, liposomes.
- Material science characterization: nanoparticles, polymers, thin films, catalysts, fibers, and metals.
- Low-dose imaging: suitable for beam-sensitive biological or polymer samples.
- Tilt-series for manual tomography: even without 3D recon software, users can acquire tilt datasets.
- Digital measurements & morphometrics: particle size, shape analysis, and population statistics.High-resolution automated image stitching for large-area TEM mapping.
