Electron microscopes can excite electrons to form images that magnify micron and nanostructures up to 10 million times, providing amazing levels of fine magnification and allowing researchers to observe even individual atoms. CD BioSciences can provide innovative solutions for electron microscopy and microanalysis. We offer Philips CM200 Transmission Electron Microscope instruments that allow customers to combine high-resolution imaging with physical, elemental, chemical and electrical analysis to obtain usable data from the widest range of samples.
A transmission electron microscope (TEM) is comparable in design to an inverted light microscope. An electron gun at the top of the column produces a beam of electrons, which are accelerated down the column, and focused into a coherent beam by electromagnetic lenses onto the sample. The specimen, mounted on a small copper grid, must be thin enough to allow the beam to pass through it. The objective lens forms an image of the sample, which is further magnified by the imaging lenses below. The image is projected onto the fluorescent screen at the bottom of the column. In various positions in the column are a series of apertures, which serve to eliminate any stray electrons from the image forming process.
RECOMMENDED SAMPLE SIZE: Grid size is 3 mm diameter, samples should be < 100 nm thick. Initial sample fixation for biological samples should not exceed 1 mm³ (prior to sample dehydration & embedding).
The Philips CM200 TEM is a high resolution Transmission Electron Microscope capable of operating up to 200kV.
Attachments include a full cryo setup with an EDAX EDS system and Gatan 678 Image Filter and P/EELS, and Gatan 832 SC1000 CCD camera, allowing for full imaging and analytical capability. This makes it ideal for high resolution imaging and analysis of nanotechnology samples includingnanoparticles and nanotubes. It is also used routinely for imaging of biological and mineralogical samples.
