These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on nickel 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 as 25 or 50 grids in a grid box.
Formvar carbon support films can be applied to other grid sizes, material or type. Further details available on request.
