Ultra-smooth carbon foils, manufactured by ACF Metals, have been prepared in ultra-clean conditions to yield films that are effectively structureless when viewed at high magnifications in the EM. In addition they come free of any contaminant particles. They form ideal substrates for the examination of fine particle materials where the absence of confusing background information can be vital. The foils are supplied in packs of two, mounted on mica sheets and can be provided in any thickness specified by the user. The foils can be floated off onto a clean water surface and have sufficient area to cover about 100 grids.
Provided in packs of 2.
