Quantifoil Holey Carbon Grids

The supporting mesh (copper, gold or nickel) is available with distinct numbers. Higher mesh numbers (400) indicate closely spaced bars and provide higher stability, whereas lower numbers (200) provide larger free faces.

The Quantifoil® carbon film has circular holes of defined size and interspace, e.g. R 2/1 (pictured) has holes of 2 µm diameter with an interspace of 1 µm in both dimensions. Higher magnifications usually require smaller holes and vice versa.
