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.
