Abstract

There is provided an apparatus for molding a thermoplastic material into a homogenous sample body having a predetermined shape, the apparatus comprising: (a) a main body () comprising a first opening (), a second opening and a hollow bore () connecting the first opening () with the second opening, the hollow bore () being adapted to receive a separation foil shaped to cover at least a part of the hollow bore surface; (b) a piston () adapted to fit moveably into the hollow bore () containing the separation foil; (c) a base plate () comprising a protrusion, wherein the base plate () is adapted to be inserted into the first opening () in such a manner that the protrusion extends into a part of the hollow bore () containing the separation foil, and wherein the base plate () is adapted to transfer heat from a heating unit to a thermoplastic material () resting on the protrusion (); (d) a vacuum connector () adapted to be connected to a vacuum source; (e) a lid () adapted to fit moveably into the second opening and adapted to apply a force to the piston () when the vacuum connector () is connected to the vacuum source such that the piston () applies a compressing force to the thermoplastic material () resting on the protrusion. There are further provided a method and a system for molding a thermoplastic material into a homogenous sample body having a predetermined shape.
