Quantifoil S7/2 holey carbon films

Product Description

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).

Square hole, size 7 x 7µm, bar width 2µm, pitch 9µm.

Quantifoil type: S7/2

Quantifoils are supplied as 10 grids in a grid box.

Consistent Performance across Applications

The Quantifoil S7/2 holey carbon films provide uniform and reproducible sample support, ensuring high-quality results in TEM imaging. Their regular hexagonal arrangement of holes allows for optimal particle distribution, minimizing background noise and enhancing image clarity. Researchers working in both academic and industrial laboratories can trust these grids for consistent results across a wide range of biological and materials science applications.


High Electron Transparency

With a film thickness of approximately 12 nm and well-defined holes, Quantifoil S7/2 grids offer exceptional electron transparency. This quality is crucial for cryo-electron microscopy and low dose techniques by allowing superior imaging of delicate samples without excess scatter. Such transparency helps maximize data quality and facilitates high-resolution structural analysis at a molecular level.
