A method for plasma-assisted treatment of internal surfaces of a hollow body, the fluid separator and the use thereof

The present invention relates to the treatment of internal surfaces of a hollow body, on whose inner surfaces of regions with different surface properties such. B. be generated with hydrophilic and hydrophobic properties. The invention further fluid separators, based on these hollow bodies and exhibit areas with different surface properties concerned. find use such fluid separators in medical technology and analysis, in particular biochemical analysis.
