TOXICITY EVALUATION DEVICE OF NANO MATERIAL HAVING ACTIVE FLOW CONTROLLER

摘要

The present invention relates to an apparatus for evaluating the toxicity of a nanomaterial, so as to accurately evaluate the toxicity of a nanomaterial in microconcentrations, and to significantly secure the uniformity of concentrations of the nanomaterial present inside the apparatus for evaluating the toxicity. The apparatus comprises: a nanomaterial generation device; transporting pipes for enabling the nanomaterial generated from the nanomaterial generation device to be connected to a plurality of mouse houses, wherein the transporting pipes of the nanomaterial generated from the nanomaterial generation device are individually connected to the mouse houses, respectively; a plurality of mouse chambers constituted with a dual wall, which are positioned inside the mouse houses; and a differential pressure-type flow controller positioned on the terminal ends of the mouse chambers.
