Quantifoil R2/2 Holey Carbon Films - Circular

Product Description

Quantifoil R2/2 Holey Carbon Films - Circular 

Quantifoil^®, produced by semiconductor lithographic techniques, are 15 - 20nm thick perforated carbon films with precise, well defined holesizes, 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 2µm
Quantifoils are supplied as 10 grids or 100 grids in a grid box.

Optimal Support for TEM and Cryo-EM

Quantifoil R2/2 Holey Carbon Films are purpose-built for state-of-the-art imaging in TEM and cryo-electron microscopy, enabling superior resolution for single-particle analysis, tomography, and structural biology. The precisely patterned holes and ultra-flat surface reduce background signal, delivering crisp, clear data for biological and materials science studies.


Reliable Construction and Compatibility

Crafted from ultra-high purity amorphous carbon on a standard 3.05 mm copper grid, these films maintain structural integrity under stringent imaging conditions. Non-conductive and non-poisonous, the films are insoluble, vacuum compatible, and suitable for cryogenic processes, meeting strict EM grade standards for laboratories and research institutions.


Simple Handling and Storage

Each Quantifoil R2/2 grid is supplied in a contamination-resistant grid box, with handling advice emphasizing the use of fine tweezers and gloves to ensure sample purity. Grids should be stored at ambient temperature in dry, dust-free areas, maintaining shelf life and optimal surface quality for your experiments.
