Quantifoil with square holes, or which is in the form of a square mesh, with relatively thin "bars" can be used in conjunction with TEM work, where the carbon film being used is too thin to span the distance between grid bars or to support sections from which EDS is being done. The square hole film is also useful for particles that are larger than one of the 7x7 µm holes. Quantifoil S7/2 represents the optimum geometry when ones requires not only good mechanical stability on the one hand, but also maximum open area.

Other square mesh parameters:
Square hole size: ~ 7 µm
Bar width: ~ 2 µm
Repeat Distance: 9 µm

The Quantifoil holey films are available on "standard, stock" grid mesh, namely 200, 300, 400, and 100x400 mesh, in Cu, Ni, Au and Rh plated Cu. Other grid meshes and other grid constructions are possible, of course, but on special order and for a higher price.

Special note:
For the SPI Multi-Slot TEM grid only, the Quantifoil S 7/2 pattern is supported with a Formvar® film in order to make the entire sample more stable.

All Quantifoil grids come 100 grids per pack, nicely packaged in an SPI Slide-A-Grid™ Storage Box.
