Hollow-fiber membrane filter is a kind of semi-membrane which is made of highly molecule Material adopting special technology. It appears hollow thin pipe shape,the wall of the pipe micro hollow,Under the action of the pressure,the original liquid flow in and out of the membrane, the liquid or small molecule,may pass through the membrane,after collecting and become filter liquid,the high molecule goods protein, nucleic acid, alymose and glue particle are prevented in the membrane surface,The original liquid which is circularly flowed will be taken away and become shrink liquid so that the goal of goods separating, shrinking and extracting is reached.
