Abstract
A process for the preparation of a single crystal of a biopolymer by growth from a solution, which 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 means for fractionating the solution and independently crystallizing the resultant fractions.
