About this item
QUANTIFOIL® is a carbon film for electron microscopy or low-energy electron point source microscopy.
- Mounted on copper, nickel or gold grids
- Foil is 12 nm thick
- Thicknesses between 10 and 25 nm upon request
QUANTIFOIL® is a perforated support foil with pre-defined hole size, shape and arrangement. It has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) microscopy when compared with conventional holey film.
In the Multi A foil the pattern of hole sizes, shapes and arrangements is repeated. In addition to circular holes, the pattern includes oval-shaped ones which appear round at high tilt angles (~70°). The diameters of the round holes are about 1, 1.4, and 2 µm, and the bar widths range from 0.5 to 4 µm. The oval holes in the foil have a dimension of 8×2 µm and 4×1 µm.
The surface properties of QUANTIFOIL holey carbon support film, especially the wetting properties, may have to be adapted according to one's particular requirements. Untreated aging QUANTIFOIL® tends to be hydrophobic. Hydrophillicity of the foil can be achieved by glow discharging in residual air or by metal coating.
