These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on copper grids. The composite films have extra resilience and strength compared with carbon films. They are recommended for use where the grid has to undergo several processing steps during specimen preparation.
Supplied either in packs of 25 or 50 grids in a grid box depending on each particular product.
Formvar carbon support films can be applied to other grid sizes, material or type. Further details available on request.
