Electron Microscopes
JEOL JEM-1400 120 keV and JEOL JEM-2000 EXII Transmission Electron Microscopes
The core (transmission) electron microscopy laboratory at Colorado State University is a research and service facility, serving the biological and materials research communities at CSU. It is open to state, university, and outside users.
We provide imaging and preparation for transmission electron microscopy. Instrument use and technician services are available on a recharge fee basis. Clients can be trained in specimen preparation and to use the instruments themselves or can request assistance from the staff.
The Electron Microscopy Laboratory has equipment for imaging and analyzing specimens by routine methods. The laboratory also houses equipment for embedding and sectioning specimens.
Equipment
JEOL JEM-1400 120kV Transmission Electron Microscope is equipped with several different specimen holders (a single specimen holder, ±26°; a high tilt specimen holder, ±70°; a Fischione dual axis Tomography holder, ±70°; and a Gatan liquid nitrogen-cooled specimen holder, ±70°), an Orius fastscan digital camera, and a Gatan Ultrascan high-resolution digital camera. Direct magnification range on this TEM is between 50x and 1,200,000x.
JEOL JEM-2000EXII Transmission Electron Microscope is equipped with a ±60° tilting (goniometer) stage, operates at accelerating voltages from 80kV to 200kV, and has a magnification range from 50x to 500,000x. This TEM is capable of selected area diffraction from 100 to 2,500mm. Two specimens can be loaded simultaneously. Images are currently captured on film, which is processed daily.
Preparatory equipment:
- Ultramicrotomes: Riechert Ultracut E, and PorterBlum MT2B
- Glass knife breaker
