VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG VON BIOPOLYMER-EINKRISTALL.

摘要

A process for the preparation of a single crystal of a biopolymer by growth from a solution comprises continuously changing one factor having an influence on the conditions for crystallization of a solution of a biopolymer, fractionating the solution, and independently crystallizing the resultant fractions. The process may be carried out by an apparatus comprising a means for feeding a crystallizing agent solution, a means for feeding a biopolymer solution, a means for producing a series of changes of predetermined crystallization conditions, said means continuously changing at least one factor having an influence on the conditions for crystallization of the biopolymer solution, and a means for fractionating the solution and independently crystallizing the resultant fractions.
