QUANTIFOIL® TEM Substrates

Support Grids or Substrates for Transmission Electron Microscopy

QUANTIFOIL® Holey Carbon Film is a perforated support foil with a pre-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 or 300 mesh. They have advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) microscopy when compared with conventional holey film.

Four reasons to use Quantifoil:
  1. With the known size of the pore of the Quantifoil, one can estimate the size of a particle observed directly.
  2. With the defined size and pitch of the holes in the Quantifoil one can use automated electron microscopy for the first time.
  3. The Quantifoil 7/2 gives a good portion of "free" area.
  4. Hole size and hole distribution uniform over a wide range.
