Electron Microscopy Sciences Quantifoil® R 2/1, 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 2 µm. Space between holes is 3 µm. Center to center is 3 µm. Types with 2 µm holes are recommended for magnifications between 30.000x and 40.000x. - EMS
