Quantifoils and other EM Supports

Specially developed for cryo electron microscopy, these ultra-stable gold supports consist of a 500Å thick layer of gold foil with a regular array of micrometer sized holes, suspended across square gold mesh. This reduces movement of frozen sections during imaging under the electron beam, resulting in improved image contrast and better 3D reconstructions from less data. Quantifoil & C-Flat Ultra-Flat Holey Carbon Films QUANTIFOIL® holey carbon films are produced by a semiconductor lithographic process. They are available with different hole sizes, shapes and arrangements. QUANTIFOIL® provide a high percentage of open area in addition to minimising total specimen thickness. The thickness of the foil is about 20nm, although only 10nm of carbon is evaporated onto the plastic. QUANTIFOIL® with circular holes is mainly used in Cryo-EM. The roundness of the holes is advantageous for the formation of an ice layer of constant thickness. The hole size that is chosen depends on the magnification used and on whether or not one wishes to include a support film in the image. C-Flat™ is an ultra-flat, holey, carbon-coated TEM support grid for transmission electron microscopy. Unlike some other holey carbon films, C-flat™ is manufactured without plastics, so it is clean and without residue and can be used straight from the box. Made with patent pending technology, C-flat™ provides an ultra-flat surface that results in better particle dispersion and more uniform ice thickness. Patterning is done using deep-UV projection lithography, ensuring the most accurate and consistent hole shapes and sizes down to sub-micron features.

These resilient, ultra-smooth, low stress inorganic SiN support films have been developed to enable specific nanotechnology and molecular biology research and are manufactured using the latest state-of-the-art semiconductor and MEMS fabrication techniques. These support films have the advantages of being chemically and mechanically robust and able to withstand temperatures to 1000°C. They are extremely stable and suitable to conduct a variety of nanotechnology experiments with particles or cells mounted directly on the support films. They provide a carbon-free, low background TEM specimen support. Benefits of SiN Windows • High resistance to temperature, acids, bases and solvents • Clean, ultra-flat, high planarity, low background, low scattering • Large viewing area without obstruction across the entire window • Carbon free and plasma cleanable See more via the following link: https://taab.co.uk/pdf-products.php?cat_id=3&sub_cat_id=237&pdf_id=385 Other Specimen Supports Formvar, Carbon, Graphene & Graphene Oxide Films
