BSC Class II Type A2 Biological Safety Cabinet

Kalasi II Mtundu A2/B2 Biological Safety Cabinet

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

Mukalowa mu labotale yofufuzira, pali zida zomwe nthawi zambiri zimatchulidwa ndi mayina osiyanasiyana: cell culture hood, tissue culture hood, laminar flow hood, PCR hood, benchi yoyera, kapena biosafety cabinet.Chinthu chofunika kukumbukira, komabe, si onse a "hood" omwe amapangidwa mofanana;kwenikweni, ali ndi mphamvu zosiyana kwambiri zotetezera.Ulusi wamba ndi wakuti zipangizo zimapereka mpweya wa laminar kwa malo ogwirira ntchito "oyera", koma nkofunika kudziwa kuti si zipangizo zonse zomwe zimapereka antchito owonjezera kapena chitetezo cha chilengedwe.Makabati a Biosafety (BSCs) ndi mtundu umodzi wa zida za biocontainment zomwe zimagwiritsidwa ntchito muzinthu zamoyo. ma laboratories kuti apereke chitetezo kwa ogwira ntchito, chilengedwe, ndi zinthu.Ma BSC ambiri (mwachitsanzo, Class II ndi Class III) amagwiritsa ntchito zosefera zapamwamba za mpweya (HEPA) mu utsi ndi makina operekera kuti apewe kukhudzana ndi zoopsa zamoyo.

Biological Safety Cabinet (BSC), yomwe imadziwikanso kuti Biosafety Cabinet imagwiritsidwa ntchito kwambiri pogwira zitsanzo za tizilombo toyambitsa matenda kapena ntchito zomwe zimafuna malo ogwirira ntchito.Kabati yachitetezo chachilengedwe imapanga kulowa ndi kutsika kwa mpweya komwe kumapereka chitetezo cha oyendetsa.

Biological Safety cabinet (BSC) ndi njira yoyamba yoyendetsera uinjiniya yomwe imagwiritsidwa ntchito kuteteza ogwira ntchito ku biohazardous kapena tizilombo toyambitsa matenda ndikuthandizira kuwongolera bwino kwa zinthu zomwe zikugwiritsidwa ntchito pomwe zimasefa zonse zomwe zimalowa komanso mpweya wotulutsa.Nthawi zina amatchedwa laminar flow or tissue culture hood.needing protection measurement, monga mankhwala, pharmacy, kafukufuku wa sayansi ndi zina zotero.

Biological Safety cabinet (BSC), yomwe imatchedwanso biosafety cabinet, ndi hood kapena bokosi la glove lomwe limayenera kugwiridwa bwino ndikuwongolera zitsanzo zamoyo, mabakiteriya, tizilombo toyambitsa matenda, monga COVID-19, ndi zinthu zina zomwe zimadziwika kuti zimayambitsa khansa. carcinogens) kapena zilema zobadwa (teratogens).Zofunikira za kabati yachitetezo chachilengedwe zimafotokozedwa ndi Biological Safety Levels (BSL), yomwe imasiyanitsa ziwopsezo zaumoyo ndi chitetezo pakati pa Class 1, Class 2, Class 3, ndi Class 4.

Makina a Class II Biological Security Cabinet amapereka mpweya wosefedwa wa HEPA komanso mpweya wotulutsa wa HEPA.Makabati a Class-2 biosafety amafunikira pamaso pa tizilombo toyambitsa matenda, monga Staphylococcus aureus.Mitundu yaying'ono ya Class-2 biosafety imaphatikizapo masinthidwe a A1, A2, B1, B2, ndi C1.Makabati a Class II A2 oteteza zachilengedwe amazunguliranso 70% ya mpweya kubwerera kumalo ogwirira ntchito kwinaku akutopetsa 30% yotsalayo.Makabati a Class II B2 biosafety nthawi yomweyo amatulutsa mpweya 100% kuchoka pamalo ogwirira ntchito.Makabati a Class II C1 biosafety ndi NSF/ANSI 49 ovomerezeka ndipo amatha kusinthana pakati pa A2 ndi B2 masinthidwe.

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.

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 lagalasi likhoza kusunthidwa mmwamba ndi pansi, likhoza kuikidwa mosasamala, ndilosavuta kugwira ntchito, ndipo likhoza kutsekedwa kwathunthu kuti likhale lotseketsa, ndipo alamu yochepetsera 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 ntchito.

4. Fyuluta yapadera imayikidwa pa mpweya wotulutsa mpweya kuti athetse kuipitsidwa kwa mpweya.

5. Malo ogwirira ntchito amapangidwa ndi chitsulo chosapanga dzimbiri cha 304, chomwe chili chosalala, chosasunthika, komanso chopanda mapeto.Itha kutetezedwa mosavuta komanso moyenera ndipo imatha kuletsa kukokoloka kwa zowononga ndi mankhwala ophera tizilombo.

6. Imatengera kulamulira kwa gulu la LCD la LED ndi chipangizo chotetezera nyali cha UV, chomwe chingatsegulidwe kokha pamene chitseko cha chitetezo chatsekedwa.

7. Ndi doko lodziwikiratu la DOP, geji yokhazikika yosiyana.

8, 10 ° angle yopendekera, mogwirizana ndi lingaliro la kapangidwe ka thupi la munthu
