Electron Microscopy Sciences Quantifoil® R 1.2/20, 300 Mesh, Cu, 10/PK

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. Hole size is 1.2 µm. Space between holes is 20 µm. Center to center is 21.2 µm. Smaller holes are designed for magnifications of 50,000x or higher. - EMS
