Device and method for counter-diffusion crystal growth

摘要

The invention relates to a device which enables crystallisation (e.g. of biological macromolecules) by means of counter-diffusion. The inventive device consists of a one-dimensional space, for example a capillary tube, comprising three differently-shaped parts. The invention also relates to a block which comprises several of the aforementioned devices and which can be used to perform crystallisation experiments simultaneously under different conditions. The invention further related to a method of growing crystals by means of counter-diffusion in one-dimensional devices either under terrestrial gravity conditions or under reduced gravity conditions, preferably with the use of the block comprising several of said devices in the latter case.
