Makabati a Biosafety Cabinet Biological Safety Cabinet Biochemistry Laboratory

Kalasi II Mtundu A2/B2 Biological Safety Cabinet

Kabati yachitetezo cha labotale / kalasi ii nduna yachitetezo chachilengedwe ndiyofunikira mu labu yanyama, makamaka momwe zilili

Bilosafety cabinet (BSC) si fume hood.

Mfundo zakusankha makabati otetezedwa kwachilengedwe m'ma laboratories achitetezo chachilengedwe:

Mulingo wa labotale ukakhala m'modzi, sikofunikira kugwiritsa ntchito kabati yachitetezo chachilengedwe, kapena kugwiritsa ntchito kabati yachitetezo chachilengedwe cha kalasi yoyamba.Pamene mulingo wa labotale uli mu Level 2, pamene ma aerosols ang'onoang'ono kapena ntchito zowaza zitha kuchitika, kabati yachitetezo chachilengedwe ya Gulu I ingagwiritsidwe ntchito;pochita ndi zida zopatsirana, kabati yachitetezo chachilengedwe ya Gulu II yokhala ndi mpweya wocheperako kapena wokwanira iyenera kugwiritsidwa ntchito;Ngati mukulimbana ndi ma carcinogens, zinthu zotulutsa ma radio ndi zosungunulira zosasunthika, makabati oteteza zachilengedwe a Gulu II-B okha (Mtundu wa B2) angagwiritsidwe ntchito.Mulingo wa labotale ukakhala mu Level 3, kabati yachitetezo chachilengedwe ya Gulu II kapena Class III iyenera kugwiritsidwa ntchito;maopareshoni onse okhudzana ndi tizilombo toyambitsa matenda akuyenera kugwiritsa ntchito kabati yachitetezo chachilengedwe ya Gulu II-B (Mtundu wa B2) kapena Class III.Mulingo wa labotale ukakhala mulingo wachinai, kabati yachitetezo chachilengedwe ya mulingo wa III iyenera kugwiritsidwa ntchito.Makabati achitetezo achilengedwe a Gulu II-B atha kugwiritsidwa ntchito ngati ogwira ntchito avala zovala zodzitetezera.

Makabati a Biosafety Cabinets (BSC), omwe amadziwikanso kuti Biological Safety Cabinets, amapereka ogwira ntchito, zogulitsa, ndi chitetezo cha chilengedwe kudzera mu laminar airflow ndi kusefera kwa HEPA kwa labotale ya biomedical/microbiological.

Makabati oteteza zachilengedwe amakhala ndi magawo awiri: bokosi la bokosi ndi bulaketi.Bokosilo limakhala ndi zinthu zotsatirazi:

1. Air Sefa System

Dongosolo losefera mpweya ndilofunika kwambiri kuti zitsimikizire kuti zida izi zikugwira ntchito.Zimapangidwa ndi fan fan, duct ya mpweya, fyuluta yozungulira mpweya ndi fyuluta yakunja yotulutsa mpweya.Ntchito yake yaikulu ndikupitirizabe kupanga mpweya woyera kulowa mu studio, kotero kuti kutsika kwapansi (kuthamanga kwa mpweya) kumayenda m'dera la ntchito sikuchepera 0.3m / s, ndipo ukhondo m'dera la ntchito umatsimikiziridwa kuti ufikire masukulu a 100.Panthawi imodzimodziyo, kutuluka kwa kunja kwa kunja kumayeretsedwanso kuti ateteze kuipitsidwa kwa chilengedwe.

Pachimake chigawo chimodzi cha dongosolo HEPA fyuluta, amene amagwiritsa ntchito zinthu zapadera fireproof monga chimango, ndi chimango anawagawa magalasi ndi malata mapepala aluminiyamu, odzazidwa ndi emulsified galasi CHIKWANGWANI sub-particles, ndi kusefera Mwachangu akhoza kufika. 99.99% ~ 100%.Chophimba cha pre-sefa kapena chosefera panjira yolowera mpweya chimalola mpweya kusefedwa ndi kuyeretsedwa musanalowe mu fyuluta ya HEPA, yomwe imatha kutalikitsa moyo wautumiki wa fyuluta ya HEPA.

2. Kunja mpweya bokosi dongosolo

Dongosolo la bokosi lotayirira lakunja limapangidwa ndi chipolopolo cha bokosi lakunja, fan and duct exhaust.Chotsitsa chakunja chakunja chimapereka mphamvu yotulutsa mpweya wodetsedwa m'chipinda chogwirira ntchito, ndipo chimatsukidwa ndi fyuluta yotulutsa kunja kuti iteteze zitsanzo ndi zinthu zoyesera mu nduna.Mpweya m'dera la ntchito umathawa kuti uteteze wogwiritsa ntchito.

3. Kutsetsereka kutsogolo zenera pagalimoto dongosolo

Dongosolo lakutsogolo lazenera lakutsogolo limapangidwa ndi khomo lagalasi lakutsogolo, mota yapakhomo, makina oyendetsa, shaft yotumizira ndi switch switch.

4. Gwero lounikira ndi gwero la kuwala kwa UV lili mkati mwa chitseko cha galasi kuti zitsimikizire kuwala kwina m'chipinda chogwirira ntchito ndikuchotsa tebulo ndi mpweya m'chipinda chogwirira ntchito.

5. Gulu lolamulira liri ndi zipangizo monga magetsi, nyali ya ultraviolet, nyali yowunikira, kusintha kwa fan, ndi kuyendetsa kayendedwe ka khomo la galasi lakutsogolo.Ntchito yayikulu ndikukhazikitsa ndikuwonetsa mawonekedwe adongosolo.

Kalasi II A2 kabati yachitetezo chachilengedwe/omwe ali mgulu laopanga opanga:1. Air nsalu yotchinga kupanga kudzipatula kumalepheretsa kuipitsidwa kwamkati ndi kunja, 30% ya mpweya umatuluka kunja ndi 70% ya kayendedwe ka mkati, kuthamanga koyipa kofanana ndi laminar, osafunikira kukhazikitsa mapaipi.

2. Khomo la galasi likhoza kusunthidwa mmwamba ndi pansi, likhoza kuikidwa mosasamala, ndilosavuta kugwira ntchito, ndipo likhoza kutsekedwa kwathunthu kuti likhale lotseketsa, ndipo alamu ya malire a kutalika kwa malo imayambitsa.3.Soketi yotulutsa mphamvu m'malo ogwirira ntchito imakhala ndi socket yopanda madzi komanso mawonekedwe a zimbudzi kuti apereke mwayi waukulu kwa wogwiritsa ntchito4.Fyuluta yapadera imayikidwa pa mpweya wotulutsa mpweya kuti uthetse kuipitsidwa kwa mpweya.5.Malo ogwirira ntchito amapangidwa ndi chitsulo chosapanga dzimbiri cha 304, chomwe ndi chosalala, chosasunthika, komanso chopanda mapeto.Itha kutetezedwa mosavuta komanso moyenera komanso imatha kuletsa kukokoloka kwa zowononga ndi mankhwala ophera tizilombo.6.Imatengera kuwongolera gulu la LCD la LED ndi chipangizo choteteza nyale cha UV chomangidwira, chomwe chimatha kutsegulidwa pokhapokha chitseko chachitetezo chatsekedwa.7.Ndi doko lodziwira la DOP, geji yosiyana yosiyana siyana.8, ngodya yopendekeka ya 10°, mogwirizana ndi lingaliro la kapangidwe ka thupi la munthu.
