Carbon support films with a removable Formvar on the opposite side of the grid. When the Formvar is removed, by dipping in solvent, a pure carbon film remains. (Note: The Ultrathin Carbon Film on a Lacey Carbon Support Film, Prod. No. 01824, has no Formvar backing.) These films are stable under all EM operating conditions and are for use where the presence of a Formvar layer cannot be tolerated. Pure carbon films tend to be more delicate than those with a Formvar backing and require more delicate handling during specimen preparation than most other support films.
Carbon Type-A: Carbon support film of 15 to 25nm thickness.

Ultrathin Carbon Film on a Lacey Carbon Support Film
Pure carbon support films with no Formvar backing. This new product has an even thinner carbon film which is mounted on a Lacey carbon film. The carbon support layer lying over the holes is less than 3nm in thickness and is the thinnest support film available. It is particularly useful for high resolution microscopy of low contrast particles and is also ideal for use with the Energy Filtering TEM.
