The device which can do the virus non- life conversion of the liquid nutrient medium (100), the barrel (120) and the flame tube (130), the liquid nutrient medium entrance (140), at least the emitter of one ultraviolet ray C (145), and the liquid nutrient medium exit (150) from one which is formed coaxial cylinder (110) it includes at least. The flame tube, in order the gap (160) to form in major diameter of the flame tube and between inside diameter of the barrel, has the major diameter which conforms. The nutrient medium flows to cyclones style substantially according to the gap. The emitter of one ultraviolet ray C is placed inside the flame tube at least. The exit, in the end of the barrel, or is connected to that proximal barrel on opposite side of the entrance.< Selective figure > Figure 1A液体培地のウイルス不活化ができる装置(100)は、外筒(120)及び内筒(130)、液体培地入口(140)、少なくとも1つの紫外線Cのエミッタ(145)、及び液体培地出口(150)から構成される少なくとも1つの同軸円筒(110)を含む。内筒は、内筒の外径及び外筒の内径間にギャップ(160)を形成するように適合される外径を有する。培地はギャップに沿って実質的にサイクロン流に流れる。少なくとも1つの紫外線Cのエミッタは内筒の内部に置かれる。出口は、入口の反対側で外筒の端部で、又はその近位の外筒に連結される。【選択図】 図1A
