Kalasi II Laboratory Biosafety Cabinet

Kabati ya Biosafety imakhala ndi casing yakunja, fyuluta ya HEPA, gawo la mpweya wosiyanasiyana, tebulo logwirira ntchito, gulu lowongolera, damper yotulutsa mpweya. Chophimba chakunja chimapangidwa ndi chitsulo chopyapyala chokhala ndi ufa. Malo ogwirira ntchito ndi chitsulo chosapanga dzimbiri chokhala ndi tebulo losavuta komanso losavuta kuyeretsa. Mpweya wapamwamba wopopera mpweya ukhoza kulumikizidwa ndi njira yotulutsa mpweya ndi mwiniwake ndikuwunikira komanso kutulutsa mpweya mu kabati kumalo akunja. Dongosolo lamagetsi lowongolera lili ndi ma alarm osagwira bwino ntchito, alamu ya HEPA fyuluta ndi chitseko chagalasi chotsetsereka ndikutsegula ma alarm aatali. Chogulitsacho chimagwiritsa ntchito njira yosinthira mpweya, yomwe imatha kusunga kuthamanga kwa mpweya pamalo abwino ogwirira ntchito pamalo omwe adavotera komanso kukulitsa moyo wazinthu zazikuluzikulu monga fyuluta ya HEPA. Mpweya womwe uli pamalo ogwirira ntchito umakanikizidwa mubokosi la static pressure kudzera kutsogolo ndi kumbuyo kutulutsa mpweya. Mpweya wina watopa pambuyo pa kutha kwa fyuluta ya HEPA pogwiritsa ntchito chotsitsa chapamwamba cha mpweya. Mpweya wina umaperekedwa kuchokera kumalo olowera mpweya kudzera pa fyuluta ya HEPA kuti ikhale mpweya wabwino. Malo ogwiritsira ntchito mpweya woyera ndi gawo lokhazikika la liwiro la mpweya ndiyeno amakhala malo ogwirira ntchito aukhondo. Mpweya wotopa ukhoza kulipidwa kuchokera ku mpweya wabwino womwe uli kutsogolo kwa mpweya wolowera. Malo ogwirira ntchito ali ozunguliridwa ndi kukakamizidwa koyipa, komwe kumatha kusindikiza bwino aerosol yosayera mkati mwa malo ogwira ntchito kuti atsimikizire chitetezo chaogwiritsa ntchito.
