Advantages are an extremely high separation efficiency factor with maximum plasma yield with pure plasma and more than 50% time savings based on the doubled design of the double-chambered double cup.

Abstract: The invention relates to a method and a device for producing a moulded body having microstructures from moulding material. The method for producing a moulded body having microstructures on a carrier out of moulding material is effected by inputting a moulding material into a container (10) comprising a mould cavity (14), wherein at least one micro-structured mould (12) is provided in the mould cavity. Furthermore, the centrifugation of a container (10) is carried out until the moulding material has completely entered into the structure of the mould (12). Thereafter, the curing of the moulding material is carried out to form a moulded body having microstructures, which is then removed from the mould (12) and the container (10).
