Electron Microscopy Sciences Quantifoil® R 1.2/1.3, Ut, 200 Mesh, Cu

Electron Microscopy Sciences Quantifoil® is a perforated support foil with pre-defined hole size, shape and arrangement that has advantages in electron microscopy (em) or low-energy electron point source (leeps) 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. A foil with ~1.2 µm circular holes and a spacing of ~1.3 µm between the holes. Smaller holes are designed for magnifications of 50,000x or higher. - EMS
