A method for providing a casing () for a prefabricated column () of chromatography column material in order to manufacture a chromatography column, wherein the casing () is generated by additive manufacturing, includes the steps of rotating the column () of chromatography column material with respect to a casing material feed in a manner to successively cover a casing surface () of the chromatography column material along a contact area path (), and of arranging an amount of flowable casing material () at a current contact area () along the contact area path () at the casing surface () of the column () of chromatography column material in order to generate the casing () for the chromatography column by successively adding the solidified amount of casing material () at the contact area ().

A purification device (), for the purification of a liquid-crystal mixture, has a flow chamber () which has an inlet opening () and an outlet opening (), arranged opposite the inlet opening, in order to be able to introduce the liquid-crystal mixture into the flow chamber () and discharge it from the latter, and at least one flow distribution element () which is arranged in the flow chamber () in the region of the inlet opening (), and at least one filter element () which is arranged in the region of the outlet opening (), where a length of the flow chamber () measured in the flow direction is at least a factor of 2 greater than a greatest internal dimension of the flow chamber () transverse to the flow direction.

Purification device for a liquid-crystal mixture

The invention relates to a filling device () for dispensing a fluid into at least one container, where the filling device () has a weighing system () and a filling-needle system (). The weighing system () has a positioning device () which can be adapted to a container diameter and which may have an annular design. The weighing system () is arranged on an accommodation platform () which can be moved vertically by means of a linear unit. The filling-needle system () is arranged on a displacement unit in a position at a distance in the axial direction above the positioning device ().

Filling device and use thereof for dispensing a fluid

The invention relates to a method of preparing a birefringent marking by printing a polymerisable liquid crystal material onto at least one side of a substrate and polymerising the liquid crystal material, to a birefringent marking obtained by this method, and to the use of the birefringent marking for decorative, security, authentification and identification applications.
