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.
Made from 0.004" tantalum foil. Replaceable tantalum apertures for some microscopes (Amray and Philips). They improve the performance of the electron gun.

These standards are supplied as 1/4" (33 mm) diameter pressed pellets or metal foils, and are prepared from selected high purity elements and compounds to ensure interference free-spectra. They are suitable for use by experienced spectroscopists as well as staff training. Each of the pressed pellets is supported by a thin-walled aluminum cup which is protected from damage during handling and minimizes the risk of touching the standard materials (some of which are harmful). X-Ray Fluorescence. Na, Mg, Al, Si, P, S, Cl, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Nb, Sn, Ba, W, and Pb.
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.
QUANTIFOIL with circular holes is used in cryo-electron tomographic reconstruction. The roundness of the holes is advantageous with respect to the formation of an ice layer of constant thickness. The whole size chosen depends on the magnification used, and on whether or not one wishes to include support film in the image. Assessment of the image quality is easier when foil is included in the picture, because the power spectrum of a foil is stronger than that of unsupported ice.

QUANTIFOIL Multi A is a holey film, in which a pattern of various 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 x 2 µm and 4 x 1 µm

QUANTIFOIL with square holes and relatively narrow bars can be used in EM to support a thin carbon film, which by itself is too fragile to span a grid square. Alternatively, this holey film can directly support an object that is larger than the holes.
