Quantifoil S7/2 Holey Carbon Films

Product Description

Quantifoil S7/2 Holey Carbon Films 

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.

Optimized for TEM Applications

Quantifoil S7/2 Holey Carbon Films set the standard for consistency in TEM applications. With precision hole patterns and a thin, electron-transparent carbon layer, they deliver exceptional imaging quality. Their robust mechanical stability ensures minimal drift and damage during imaging, making them ideal for ultrathin section analysis, whether at room temperature or under cryogenic conditions.


Superior Material and Grid Construction

Manufactured from pure carbon deposited on high-quality copper grids, these films combine chemical purity with mechanical reliability. The 3.05 mm diameter grid is compatible with most TEM holders, while the S7 mesh design provides a consistent 7 m pitch for accurate sample positioning. Uniformity and surface quality enable reproducible results across multiple imaging sessions.
