Device for the thermal field flow fractionation of particles and polymers has a separating channel made from a tube

摘要

Device for fractionating particles and polymers has a separating channel made from a tube (B). Preferred Features: The tube is made from a fluorinated plastic tube and is wound around a temperature-controlled cylinder (A). The tube wound around the cylinder is placed in a temperature-controlled pipe (C). The tube is squeezed between the cylinder and the pipe.
