QUANTIFOIL® is a carbon film for electron microscopy or low-energy electron point source microscopy.
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. Alternatively, this holey film can directly support an object larger than the holes.
QUANTIFOIL® S 7/2 has a hole size of 7×7 µm. Space between holes is 2 µm. Center to center is 9 µm.
QUANTIFOIL S 35/5 hole size is 35 µm. Space between holes is 5 µm. Center to center is 40 µm.
QUANTIFOIL S 35/10 hole size is 35 µm. Space between holes is 10 µm. Center to center is 45 µm.
Ordering information: QUANTIFOIL® is delivered as a carbon foil; it can be reinforced with plastic film. The grids are packed with their coated side toward the center of the grid box.
