摘要

Provided is a device for crystallizing a biopolymer by which biopolymer crystals can be efficiently formed by applying a low voltage to a minute amount of a solution of the biopolymer to be crystallized and the state of the formation of the crystals can be observed without interference by electrodes. As electrodes for applying an electric field to a biopolymer solution, transparent electrodes, which do not interfere the formation of crystals, are used. Between electrodes (2) comprising a transparent conductor, an electrical insulating member (4) is positioned and a minute amount of a solution (1) of a biopolymer to be crystallized is held between the electrodes. By applying a low voltage supplied from a voltage generator (5) to the transparent electrodes (2), the biopolymer is efficiently crystallized. The state of the formation of the biopolymer crystals can be optically observed from the electrode side of the transparent conductor. Due to the electrical field formed by the voltage application, the alignment of the biopolymer can be controlled.
