Abstract: Disclosed is a method for unpacking a component 16 manufactured by means of a generative manufacturing process, from a particulate material fill 18. In the method, an auxiliary frame 20 having a vertical circumferential wall structure 22, open downward, is arranged above a vertical circumferential wall structure 12 of a construction box 10. In addition, a construction platform 14 of the construction box 10 is displaced upward, so that the particulate material fill 18 containing the component 16 is transferred from the construction box 10 to the auxiliary frame 20. In addition, the auxiliary frame 20 with the particulate material fill 18 containing the component, and the construction box 10 are moved away from each other, and the component 16 is unpacked from the particulate material fill 18 at least in part and is removed from the auxiliary frame 20.

Abstract: A clamping device for clamping a plurality of columns for sample preparation provides a plurality of clamping blocks and a displacement mechanism for displacing at least one clamping block relative to an opposing clamping block between an open position and a clamping position. At least three clamping blocks are retained in a row one behind the other on a guiding rail so that at least two columns can be clamped in an axial direction one behind the other between the clamping blocks. First and second slidingly displaceable clamping blocks of the least three clamping blocks are retained on the guiding rail and connected to the displacement mechanism by coupling means so that an actuation of the displacement mechanism from the clamping position into the open position brings about a displacement of all the slidingly displaceable clamping blocks and the columns are released.

Abstract: According to the invention, this object is achieved by a clamping device for clamping a plurality of columns for sample preparation which provides for a plurality of clamping blocks and a displacement mechanism for displacing at least one clamping block relative to an opposing clamping block between an open position and a clamping position. In this instance, in the open position, a column can be inserted between two opposing clamping blocks and, in the clamping position, the inserted column is clamped between the opposing clamping blocks in order to produce a fluid connection between the column and at least one of the opposing clamping blocks. In this instance, at least three clamping blocks are retained in a row one behind the other on a guiding rail so that at least two columns can be clamped in an axial direction one behind the other between the clamping blocks.
