Electron Microscopy Sciences Quantifoil® S 7/2, 200 Mesh, Ni

Electron Microscopy Sciences Quantifoil® with square holes and relatively narrow bars can be used in electron microscopy to support a thin carbon film, which by itself is too fragile to span a grid square. The quantifoil® types with square holes constitute an optimum between a maximum of open area on the one hand, and mechanical stability on the other hand. Quantifoil® r 35/5 has a hole size of 35 µm. Space between holes is 5 µm. Center to center is 40 µm. Constitutes an optimum between a maximum of open area on the one hand, and mechanical stability on the other hand. Hole size is 7x7 µm. Center to center is 9 µm. - EMS
