Quantifoil R2/1 Holey Carbon Films - Circular

Product Description

Quantifoil R2/1 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 1µm, pitch 3µm.

Quantifoil type: R 2/1

Quantifoils are supplied as 10 grids or 100 grids in a grid box.

Designed for Precision in EM Imaging

Quantifoil R2/1 grids offer a meticulously patterned, holey carbon film supported on copper for superior image consistency in both cryo-EM and TEM. Their regular R2/1 array aids in quantifiable sample placement, while the grids ultrathin carbon enhances contrast and resolution, facilitating structural biology workflows.


Optimized Surface for Sample Adherence

After glow-discharge treatment, the hydrophilic nature of Quantifoils carbon film enables optimal wetting and sample spread. This process ensures even distribution of biological specimens, reducing aggregation and improving imaging reliability in delicate cryo-EM preparations.


Customizable Mesh Sizes for Versatile Use

Available in 200 mesh, 300 mesh, or by specification, Quantifoil R2/1 Holey Carbon Films can be tailored to different experimental demands. Whether for routine TEM or advanced Cryo-EM, researchers can select grids matching their protocol requirements to maximize imaging quality.
