Electron Microscopy Sciences Quantifoil® R 5/20, 200 Mesh, Au

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 5 µm. Space between holes is 20 µm. Center to center is 25 µm. Larger holes (e.g. 3.5 Μm, 5 µm) are suitable at magnification around 20.000x. - EMS
