Coated Grids and Custom Coating Service from SPI

1.0 mm Aperture Grids

The filmed coatings will be as described, but note that what we have described as "Silicon Dioxide (SiO₂)/Monoxide (SiO)" is the result of an evaporation of SiO (silicon monoxide) at high vacuum and the end result is generally thought to be a combination of SiO₂ and SiO. In any case, for nearly all users of this product, what seems to be important is not knowing the precise composition, but knowing that in a plasma etcher, oxygen will not etch or otherwise harm the film.

The case for molybdenum grids:
These grids are used primarily for those doing high temperature studies, which would mean that any polymer, such as Formvar^®, would be degraded during the heating. Actually, SPI Supplies features the world's largest and most diverse selection of different molybednum TEM grids, so if you would prefer some other pattern, it too probably could be coated, and either for the same price or just slightly more. Just tell us what you want and we will return with a confirmation of pricing! However, for those contemplating in situ studies, do not over look the advantages of the SPI Supplies silicon nitride membrane window grids.
