Quantifoil R2/4 Holey Carbon Films - Circular

Product Description

Quantifoil R2/4 Holey Carbon Films - Circular 

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.

Precision Support for Electron Microscopy

The Quantifoil R2/4 Holey Carbon Films provide consistent specimen support for TEM, cryo-EM, and SEM systems. Each film delivers uniform hole size and array, facilitating even sample distribution and high imaging quality. Their optimal thickness and molecular purity support critical research in structural biology and material sciences, meeting strict laboratory standards.


Exceptional Chemical and Thermal Stability

Manufactured from high-purity carbon, these films withstand electron beam exposure, short autoclave cycles, most common solvents, and heat within application limits. The robust structure ensures reliable performance in demanding microscopy workflows, contributing to reproducible and clear imaging results.


Convenience and Compatibility

Packaged individually in secure grid boxes, the Quantifoil R2/4 films are easy to handle and implement in most laboratories. They are compatible with numerous microscopy platforms, supporting contemporary research needs and diverse sample types. Optional gold or nickel grids are available to match specific experiment requirements.
