Description Tech Data

Product Description

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 3.5µm dia, separation 1µm, pitch 4.5µm.

Quantifoil type: R3.5/1

Quantifoils are supplied as 10 grids in a grid box.

Characteristics of QUANTIFOIL®

The QUANTIFOIL Holey Carbon Film is about 10 to 12nm thick. Due to residuals from the production process the overall thickness of the support foil is about 20nm. In case those residuals have a negative impact on your results we recommend to wash the grids with chloroform, ethylacetat and aceton or to plasma clean them before use. They can be made more hydrophilic using standard glow discharge and plasma systems.
