JEOL JEM 1200EX Transmission Electron Microscope
Transmission electron microscopy allows high resolution imaging of thin sections of biological material and negatively stained small particles. Electron diffraction of crystalline samples can give information about the spacing of the atoms in the sample's crystalline lattice. Images from this instrument are captured with a high resolution digital camera.
The purchase of high resolution camera was funded by a Major Instrumentation Grant from the National Science Foundation (NSF).
JEOL JSM 6610LV Scanning Electron Microscope
SEM allows the observation of the surface details of a sample. This gives a magnification range of 5x to 300,000x . This microscope is equipped with four detectors that provide images of the surface topography of a sample and its elemental composition.
The design includes a low vacuum setting for samples that have excessive water content or a non-conductive surface and cannot be viewed at high vacuum. This microscope is equipped with a cold stage, which further extends its ability to look at hydrated (wet) samples.
Zeiss Axiovert 25 inverted Fluorescence Microscope with a Retiga CCD camera
The newest addition to the central facility is a Zeiss Axiovert 25 inverted fluorescence light microscope with a cooled CCD digital camera and computer for image analysis. This is a very flexible system that allows users to examine a wide range of samples including live cells. The system also allows users to make time lapse movies.
