Electron Microscopy Sciences Quantifoil Holey Carbon Film R 1.2/1.3 on Copper 200 mesh Grid
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.

Electron Microscopy Sciences Fischione Copper Tomography Grid 300 mesh
This 1.5mm square, 300 mesh grid is made from copper and is for use with Fischione tomography specimen holders. The size allows for further tilt in TEMs with small pole piece holes. An identification mark and the square shape give easy reference when rotated past 90 deg.
Electron Microscopy Sciences SEM High Resolution Au on Carbon Test Specimen, 12.5mm Pin Stub
The gold on carbon specimen is for resolution test of SE and BSE imaging and also for chemical mapping in high-resolution systems such as an Auger scanning instrument. Each test specimen has a square grid pattern with large crystals in the center of each square, and very fine crystals at the edges of each grid somedium and high resolution gap tests are performed on the same specimen. The larger crystals facets are used to assess the gray level reproduction at high resolution. Gold particles range from approximately 5nm to 150 nm.
