The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.

Biological material extraction apparatus

An apparatus and a method of firing a unit cell for a solid oxide fuel cell performs pre-sintering and main sintering using a single apparatus by adjusting a height of a setter to apply pressure. The pressure prevents warping.

Apparatus and method for plasticizing solid oxide fuel cell

The present invention relates to a firing cartridge, and more particularly, to a firing cartridge in which multiple slit grooves are formed in lateral portions positioned between an upper end portion and a lower end portion, and solid fuel cell electrodes are inserted into the slit grooves, such that the number of cells, which may be fired at the same time, is increased, and thus productivity of a solid fuel cell may be improved.
