Quantifoils®, produced by semiconductor lithographic techniques, are 15 - 20nm thick perforated carbon films with precise, well defined hole sizes, shapes and arrays. Quantifoil support films provide a high percentage of open area in addition to minimising total specimen thickness. Object distortions arising from interactions with the support film are also reduced. They are particularly suited for cryo applications, tomography and low dose microscopy (LEEP).
Circular hole, size 2µm dia, separation 4µm
Quantifoil type: R2/4
Quantifoils are supplied as 10 grids or 100 grids in a grid box.
