Quantifoil R2/1 Holey Carbon Films - Circularn

Product Description

Quantifoil R2/1 Holey Carbon Films - Circularn 

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.

Precision-Engineered for Cryo-EM and TEM

Quantifoil R2/1 Holey Carbon Films are meticulously crafted to offer uniform hole sizes and spacing, essential for high-resolution imaging in cryogenic and traditional electron microscopy. The regular pattern supports even sample distribution and minimizes background noise, contributing to enhanced data quality and reproducibility in research.


Reliable Support with High Purity Materials

Constructed using high purity carbon on a robust copper grid, these films ensure optimal mechanical stability and electron transparency. The approximately 12 nm thick carbon film supports sensitive specimens without interfering with image clarity, making it suitable for demanding laboratory workflows.


Convenient and Ready-to-Use Packaging

Each Quantifoil grid is individually boxed for protection against contamination and physical damage. Delivered pre-cleaned, they are immediately ready for sample preparation, saving users valuable time in busy lab settings. Proper storage at room temperature in a dry environment can extend shelf life beyond two years.
