TEM Window Grids
Exclusively available at TEMwindows.com
With UltraSM® TEM Windows, you can freely suspend nanoscale materials for background-free imaging. Every porous UltraSM® TEM Window contains millions-to-billions of 10-50 nm diameter pores, perfect for suspending proteins, viruses, carbon nanotubes or other nanomaterials. Combined with their nanometer thickness, UltraSM TEM Windows are ideal sample preparation supports for imaging and analyzing current-generation nanotechnology.
Features and Benefits:
Nanometer Thinness: UltraSM TEM Windows feature imaging windows with 5 to 15 nm thickness? significantly thinner than silicon nitride grids?reducing background contribution and interference for higher contrast imaging.
Uniformity: Non-Porous UltraSM TEM Windows are more consistently thin than carbon grids, reducing field-to-field variability. (Note: Porous UltraSM windows do have inherent crystalline features, but have beautiful background-free nanometer-scale pores).
Nanometer-Scale Pores: UltraSM TEM Windows are available as porous films with pores ranging from 10 to 50 nm in diameter. The pores allow simple and stable suspension of nanoscale materials for imaging without intervening background.
Silicon Composition: The elemental silicon composition of UltraSM TEM Windows remarkably increases stability at high beam currents and at high annealing temperatures. The pure silicon composition also introduces a minimal background signal, making elemental analyses of samples containing nitrogen and/or carbon possible by EDX and EELS.
Plasma Cleanable: Unlike traditional carbon grids, samples prepared on UltraSM? TEM Windows can be vigorously plasma cleaned to remove organic contamination and to improve image quality.
Isolated Poly-Crystallinity: The poly-crystalline nature of porous UltraSM? TEM Windows offers an internal calibration standard for x-ray diffraction studies. The isolated crystalline features also provide a convenient and reliable scale for high-resolution size measurements, well-characterized crystal lattice of silicon.
