  • Method and equipment for producing biopolymer crystal
    Patent number: 7402208
    Abstract: The invention provides a crystallizing method and an apparatus for producing a biopolymer capable of simplifying operations for taking out a produced crystal and mounting the crystal onto a crystal structure analyzer, thereby improving efficiency in the operations as well as reducing a labor burden. A crystallizing apparatus for producing a biopolymer crystal from a solution containing a biopolymer includes a crystal-growing chip 10 made of a material allowing electromagnetic waves to permeate through the chip, and in which a circular frame 16 is formed to retain a droplet 20 of a solution containing a biopolymer and a biopolymer crystal 28 produced in the droplet.

  • Biopolymer crystal mounting device and manufacturing method thereof
    Patent number: 7311773
    Abstract: The invention provides a biopolymer crystal mounting device with which a biopolymer crystal having been grown in a solution containing a biopolymer can be taken out of the solution. The device can be manufactured efficiently without requiring labors and can be mass-produced with high yield. A biopolymer crystal mounting device comprises: a film member 12, which is made of a material possessing permeability to an electromagnetic wave, and which is integrally formed of a loop portion 16 holding a drop of solution containing a biopolymer crystal, a neck portion 18 and a body portion 20; and a tubular member 14 including a bearing hole 22 in which the body portion of the film member is inserted and supported. Further, the film member is inserted into and secured to the tubular member.
