Sistema fluídico compuesto por lo menos de un elemento sensor como componente fluídico y por lo menos otro componente fluídico adyacente al primero, caracterizado porque, tanto sobre las superficies internas de las zonas conductoras de líquido del elemento sensor como también del componente fluídico adyacente al mismo, existe una película del mismo polímero hidrófilo. Sample-contacting surfaces, particularly of plastics components, which: (a) are physically/chemically prepared e.g. by electric discharge gas-plasma treatment; (b) are contacted with a solution of hydrophilic polymer e.g. polyether polyurethane in organic solvent; (c) allow gas displacement of liquid to leave a wet surface; (d) allow removal of solvent by natural or vacuum drying, leaving a 0.01-50, preferably 0.01-5 micron thick film. An independent claim is included for analytical apparatus having sample-wetted surfaces coated with hydrophilic polymer.
