Silicon Monoxide: Silicon monoxide produces a highly resilient support film which can withstand vigorous specimen preparation techniques. It has low background contrast, is stable under the electron beam and is less hydrophobic than carbon. We offer two types of silicon monoxide support films
(a) Formvar Stabilized with Silicon Monoxide: A Formvar film coated with a “light” layer of silicon monoxide.
(b) Silicon Monoxide Type-A: Silicon monoxide with a removable Formvar backing on the opposite side of the grid. When the Formvar is removed, by dipping in solvent, a pure Silicon Monoxide film remains. These films are stable under all EM operating conditions and for use where the presence of Formvar cannot be tolerated. Pure Silicon Monoxide is more delicate than those with Formvar backing and require more careful handling during specimen preparation.
