QUANTIFOIL ® Holey Carbon supports are a flat film of carbon, 10-12 nm thick, on a cryo-electron microscopy (cryo-EM) grid. They provide a low-background sample support ideal for high-resolution cryo-EM data collection.

The growing product portfolio encompasses UltrAuFoil ® Holey Gold supports for high-throughput, high-resolution SPA, robust supports with larger open viewing areas for FIB-milling and tomography, and finder grids for CLEM and other integrative methods.

An ultra-flat, holey carbon-coated support grid for TEM. Manufactured without plastics, it is clean and without residue. Ultra-flat for better particle dispersion and more uniform ice thickness.

Holey carbon films have holes of various sizes. In addition to providing support, the increased image contrast in the regions of the holes compared to regions of film is also of benefit. Typical applications include biological and materials science and cryo-TEM. Supplied as 25 or 50 grids in a …

Quantifoil is a perforated support foil with a precisely pre-defined hole size, shape, and arrangement.

C-flat™ is an ultra-flat, holey carbon-coated TEM support grid for transmission electron microscopy (TEM). Unlike competing holey carbon films, C-flat™ is manufactured without plastics, so it is clean upon arrival and the user has no residue to contend with.

Support Grids or Substrates for Transmission Electron Microscopy. Quantifoil ® Holey Carbon Film is a perforated support foil with a p re-defined hole size, shape and arrangement. They are offered with circular and square, orthogonally arranged holes. The film is mounted on a standard Ø3mm Cu, Au, or Ni TEM grid with 200, 300 or 400 mesh.
