Ultra-thin carbon support film, 3nm

Ultra-thin support films are carbon films with a removable Formvar® backing on the opposite side of the grid. The Formvar is then removed by dipping in solvent and the pure carbon film remains. These films are stable under all EM operating conditions and can be used where the presence of a Formvar layer is not acceptable. As thin pure carbon films alone have the tendency to be more delicate than those with a Formvar backing support they require more delicate handling during specimen preparation. Leaving the Formvar in place until sample preparation is complete ensures the carbon film remains intact.

These carbon films are available on 3.05mm dia copper grids.
