QUANTIFOIL® with square holes

S 7/2

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.

The table below gives an overview of the available QUANTIFOIL® types with square holes.
