A capillary made of plastics material that is suited for use in capillary electrophoresis. The capillary has its inner surface chemically modified for the generation of properties different from those of the original plastic capillary material. In the process of producing such capillaries, a premanufactured capillary is treated with a chemical reagent which generates functional groups directly on the capillary surface or generates attachment sites, on the capillary surface to which functional groups are later bonded.
