Tube for collecting a liquid containing at least one hydrophobic component which is prevented from adhering to the internal wall of the tube

摘要

The tube according to the invention is intended for collecting two or more different components with different densities, at least one of these components being hydrophobic. The tube 1 is open at one of its ends 2a and is closed at its other end 2b, and a sealing element 4 closes the open end. A hydrophobic material 3, which becomes fluid when a centrifugal force of 500 to 1500 g is applied to it, is fixed in the form of a membrane to the inner surface of the tube. The surface and the hydrophobic component, once it has been fixed to the surfaces, flows along the flow surface or is absorbed on it. Application: collection of blood. <IMAGE>
