Laboratory Biosaftety Cabinet Class II Type A2 Ndi Class II Type B2

Kalasi II Mtundu A2/B2 Biological Safety Cabinet

Biological Safety cabinet (BSC) ndi zida zotetezera zoyeretsera mpweya zooneka ngati bokosi zomwe zimatha kuletsa tinthu tating'onoting'ono toyambitsa matenda kuti tifufutike poyesa.M'madera a microbiology, biomedicine, genetic engineering, ndi kupanga zinthu zamoyo, amagwiritsidwa ntchito kwambiri pa maphunziro a sayansi, malangizo, kufufuza zachipatala, ndi kupanga.Ndilo gawo lofunikira kwambiri la zida zodzitchinjiriza pachitetezo cha labotale ya biosafety pamlingo woyamba.

Ntchito ya Biological Security Cabinet:

Fyuluta ya air-effective particulate air (HEPA) yomwe ili kunja kwa mpweya imasefa mpweya wakunja, momwemo kabati yotetezera zachilengedwe imagwirira ntchito.Imasunga kupanikizika koyipa mkati mwa nduna ndipo imagwiritsa ntchito mpweya woyima kuti iteteze ogwira ntchito.Kuphatikiza apo, mpweya wa nduna uyenera kusefedwa ndi fyuluta ya HEPA kenako ndikutulutsidwa mumlengalenga kuti muteteze chilengedwe.

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

Nthawi zambiri sikofunikira kugwiritsa ntchito kabati yachitetezo chachilengedwe kapena kabati yachitetezo chachilengedwe ya kalasi I pomwe mulingo wa labotale uli 1. Pogwira ntchito ndi zida zopatsirana, kabati yachitetezo chachilengedwe ya Gulu II yokhala ndi mpweya wocheperako kapena wokwanira iyenera kugwiritsidwa ntchito;pamene mulingo wa labotale uli Level 2, kabati yachitetezo chachilengedwe ya Class I itha kugwiritsidwa ntchito ngati ma aerosols ang'onoang'ono kapena splashing zitha kuchitika;Makabati a chitetezo chachilengedwe a Gulu II-B okha (Mtundu wa B2) ndi omwe ayenera kugwiritsidwa ntchito pogwira ntchito ndi ma carcinogens, zida zotulutsa ma radiation, ndi zosungunulira zosakhazikika.Kabati ya Gulu la II-B (Mtundu wa B2) wotheratu kwathunthu kapena kalasi yachitatu yachitetezo chachilengedwe iyenera kugwiritsidwa ntchito pamachitidwe aliwonse okhudzana ndi tizilombo toyambitsa matenda pomwe mulingo wa labotale uli mu Level 3. Khabati lachitatu lathunthu lachitetezo chachilengedwe liyenera kugwiritsidwa ntchito ngati mulingo wa labotale uli mlingo 4. Ogwira ntchito akavala zida zotetezera kupanikizika, makabati achitetezo achilengedwe a Gulu II-B atha kugwiritsidwa ntchito.

Bungwe la Biosafety Cabinets (BSC), yomwe imadziwikanso kuti Biological Safety Cabinets, imapereka chitetezo kwa ogwira ntchito, malonda, ndi chilengedwe kudzera mu mpweya wa laminar ndi kusefera kwa HEPA kwa labotale ya biomedical/microbiological.

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

1. Air Sefa System

Njira yofunika kwambiri yowonetsetsa kuti chipangizochi chikugwira ntchito ndi makina osefera a mpweya.Amapangidwa ndi fyuluta yakunja yotulutsa mpweya, chowotcha, cholumikizira mpweya, ndi zosefera zinayi zonse.Cholinga chake chachikulu ndikubweretsa mpweya wabwino mosalekeza, kuwonetsetsa kuti kutsika kwa malo ogwirira ntchito (kutuluka kwa mpweya) sikuchepera 0.3 m / s komanso kuti ukhondo ndi wotsimikizika kukhala magiredi 100.Pofuna kupewa kuipitsidwa kwa chilengedwe, kutuluka kwa kunja kwa kunja kumayeretsedwanso panthawi imodzi.

Fyuluta ya HEPA ndiye gawo lalikulu la machitidwe.Chimango chake chimapangidwa ndi chinthu chapadera chomwe sichingayaka moto, ndipo mapepala a malata amagawanika kukhala ma gridi.Ma gridi awa amadzazidwa ndi ma emulsified glass fiber sub-particles, ndipo mphamvu ya fyuluta imatha kufika 99.99% mpaka 100%.Kusefa ndi kuyeretsa mpweya usanalowe mu fyuluta ya HEPA kumatheka ndi chivundikiro chosefera kapena kusefa pa mpweya, zomwe zingawonjezere moyo wa HEPA fyuluta.

2. Kunja mpweya bokosi dongosolo

Dongosolo la bokosi lotulutsa mpweya wakunja limapangidwa ndi njira yotulutsa mpweya, fan, ndi chipolopolo cha bokosi lakunja.Kuti muteteze zitsanzo ndi zinthu zoyesera mu kabati, chowotcha chakunja chimatulutsa mpweya wonyansa kuchokera kumalo ogwirira ntchito mothandizidwa ndi fyuluta yakunja.Kuteteza wogwiritsa ntchito, mpweya womwe uli pamalo ogwirira ntchito umaloledwa kuchoka.

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. Chitseko cha galasi chikhoza kutsegulidwa ndi kutsekedwa kwathunthu kuti asatseke, ndi zizindikiro zoletsa kutalika kwa malo.Ikhozanso kusinthidwa mmwamba ndi pansi ndikuyika paliponse.3.Kuti wogwiritsa ntchitoyo asamavutike, socket yotulutsa mphamvu m'malo ogwirira ntchito imakhala ndi socket yopanda madzi komanso mawonekedwe a zimbudzi.4.Kuchepetsa kuipitsidwa kwa mpweya, fyuluta yeniyeni imayikidwa pa mpweya wotulutsa mpweya.5.Malo ogwirira ntchito amapangidwa ndi chitsulo chosapanga dzimbiri cha 304 chopanda msoko, chowoneka bwino komanso chopanda nsonga.Zitha kuletsa zokokoloka ndi mankhwala ophera tizilombo kuti zisakokoloke ndipo ndizosavuta kupha 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 lozindikira la DOP, geji yosiyana yosiyana siyana.8, ngodya yopendekera ya 10°, mogwirizana ndi lingaliro la kapangidwe ka thupi la munthu.
