IiKhabhinethi zoKhuseleko lweBhayoloji kwiKhabhinethi yeLebhu yeBiochemistry

Udidi lwe-II lweKhabhinethi yoKhuseleko lweBhayoloji ye-A2/B2

Ikhabhathi yokhuseleko lwebhubhoratri / iklasi iikhabhathi yokhuseleko lwebhayoloji iyimfuneko kwilebhu yezilwanyana, ngakumbi kwimeko

Ikhabhinethi ye-biosafety (BSC) ayiyiyo i-chemical fume hood.

Imigaqo yokukhetha iikhabhathi zokhuseleko lwebhayoloji kwiilabhoratri zokhuseleko lwendalo:

Xa inqanaba lebhubhoratri lilinye, akuyomfuneko ngokubanzi ukusebenzisa ikhabhathi yokhuseleko lwebhayoloji, okanye usebenzise ikhabhathi yokhuseleko lwebhayoloji yeklasi I.Xa inqanaba lebhubhoratri liNqanaba lesi-2, xa i-aerosols ye-microbial okanye imisebenzi yokutshiza ingenzeka, iKhabhinethi yoKhuseleko lwe-biological ye-Biological ingasetyenziswa;xa ujongene nezinto ezithathelwanayo, iKhabhinethi ye-Biological ye-biological ye-biological ene-party okanye i-ventilation epheleleyo kufuneka isetyenziswe;Ukuba ujongene neekhemikhali ze-carcinogens, izinto ze-radioactive kunye ne-solvents eziguquguqukayo, kuphela i-Class II-B i-exhaust epheleleyo (Uhlobo lwe-B2) iikhabhinethi zokhuseleko lwe-biological zingasetyenziswa.Xa inqanaba lebhubhoratri likwiNqanaba lesi-3, kufuneka kusetyenziswe iKhabhinethi yoKhuseleko lwebhayoloji yeKlasi II okanye iClass III;yonke imisebenzi ebandakanya izinto ezosulelayo kufuneka isebenzise iKlasi II-B egqitywe ngokupheleleyo (uHlobo lwe-B2) okanye iKhabhinethi yoKhuseleko lwebhayoloji yoDidi III.Xa inqanaba lebhubhoratri likwinqanaba lesine, kufuneka kusetyenziswe inqanaba le-III lekhabhinethi yokhuseleko lwebhayoloji.Udidi II-B iikhabhathi zokhuseleko lwebhayoloji zinokusetyenziswa xa abasebenzi benxibe iimpahla ezikhuselayo zoxinzelelo.

IiKhabhinethi zoKhuseleko lweBhayoloji (BSC), ezikwabizwa ngokuba ziiKhabhinethi zoKhuseleko lweBhayoloji, zibonelela ngabasebenzi, imveliso, kunye nokhuseleko lokusingqongileyo ngokuqhutywa kwe-laminar airflow kunye ne-HEPA yokucoca ilebhu yebhayomedical/microbiological.

Iikhabhathi zokhuseleko lwebhayoloji zibandakanya iinxalenye ezimbini: umzimba webhokisi kunye nesibiyeli.Umzimba webhokisi ubandakanya ikakhulu ezi zinto zilandelayo:

1. Inkqubo yoHluzo loMoya

Inkqubo yokucoca umoya yeyona nkqubo ibalulekileyo yokuqinisekisa ukusebenza kwesi sixhobo.Iqukethe i-fan yokuqhuba, i-air duct, i-air filter ejikelezayo kunye ne-exhaust air filter yangaphandle.Umsebenzi walo oyintloko kukwenza ngokuqhubekayo umoya ococekileyo ungene kwi-studio, ukwenzela ukuba i-downdraft (i-airflow vertical) isantya sokuhamba kwindawo yokusebenza ayikho ngaphantsi kwe-0.3m / s, kwaye ukucoceka kwindawo yokusebenza kuqinisekisiwe ukufikelela kumabakala angama-100.Ngelo xesha, ukuhamba kwangaphandle kwangaphandle kuhlanjululwe ukukhusela ukungcoliseka kwendalo.

Inxalenye ephambili yenkqubo yi-HEPA filter, esebenzisa izinto ezikhethekileyo zomlilo njengesakhelo, kwaye isakhelo sahlulwe sibe yigridi ngamaphepha e-aluminium e-corrugated, azaliswe ngamasuntswana e-emulsified glass fiber, kunye nokusebenza kakuhle kokucoca kunokufikelela. 99.99%~100%.Isigqubuthelo sokucoca kwangaphambili okanye isihluzi sangaphambili kwindawo yokungenisa umoya sivumela umoya ukuba uhlanjululwe kwangaphambili kwaye uhlanjululwe ngaphambi kokungena kwisihluzo se-HEPA, esinokwandisa ubomi benkonzo yesihluzo se-HEPA.

2. Inkqubo yebhokisi yomoya yokukhupha yangaphandle

Inkqubo yebhokisi yokukhupha yangaphandle ineqokobhe lebhokisi yokukhupha yangaphandle, ifeni kunye nombhobho wokukhupha.I-fan yokukhupha yangaphandle inika amandla okuphelisa umoya ongcolileyo kwigumbi lokusebenza, kwaye ihlanjululwe ngesihluzo sokukhupha sangaphandle ukukhusela iisampuli kunye nezinto zokulinga kwikhabhinethi.Umoya kwindawo yomsebenzi ubalekela ukukhusela umqhubi.

3. Inkqubo yokuqhuba ifestile yangaphambili

Inkqubo yefestile yokutyibilika yangaphambili yenziwe ngumnyango weglasi wangaphambili, ucango lwemoto, indlela yokutsala, ishaft yokuhambisa kunye nokutshintsha umda.

4. Umthombo wokukhanyisa kunye nomthombo wokukhanya we-UV ubekwe ngaphakathi komnyango weglasi ukuqinisekisa ukukhanya okuthile kwigumbi lokusebenza kunye nokucoca itafile kunye nomoya kwigumbi lokusebenza.

5. Iphaneli yokulawula inezixhobo ezifana nokunikezelwa kwamandla, isibane se-ultraviolet, isibane sokukhanyisa, i-fan switch, kunye nokulawula ukuhamba komnyango weglasi wangaphambili.Umsebenzi ophambili kukuseta nokubonisa ubume benkqubo.

Udidi II A2 ikhabhathi yokhuseleko lwebhayoloji/abalinganiswa abaphambili bekhabhathi yokhuseleko lwebhayoloji:1. Uyilo lokuhlukaniswa kwekhethini lomoya luthintela ukungcoliseka kwangaphakathi nangaphandle, i-30% yokuhamba komoya ikhutshwe ngaphandle kunye ne-70% yomjikelezo wangaphakathi, uxinzelelo olubi lokuhamba kwe-laminar, akukho mfuneko yokufaka imibhobho.

2. Ucango lweglasi lunokuthi luhanjiswe phezulu naphantsi, lunokubekwa ngokungqongqo, lusebenza lula, kwaye lunokuvalwa ngokupheleleyo ukwenzela inzala, kunye ne-alarm yobude bokuphakama obumiselweyo.3.I-socket yokuphuma kwamandla kwindawo yokusebenza ixhotyiswe nge-socket engenamanzi kunye ne-interface ye-sewage ukubonelela ngokulula kakhulu kumqhubi4.Isihluzo esikhethekileyo sifakwe kwi-exhaust air ukulawula ungcoliseko oluphumayo.5.Indawo yokusebenza yenziwe ngentsimbi ye-304 ekumgangatho ophezulu, egudileyo, engenamthungo, kwaye ayinaziphelo ezifileyo.Inokukhutshwa ngokulula nangokucokisekileyo iintsholongwane kwaye inokuthintela ukukhukuliseka kwezinto ezitshabalalisayo nezibulala iintsholongwane.6.Yamkela ulawulo lwepaneli ye-LCD ye-LED kunye nesixhobo sokukhusela isibane se-UV esakhelwe ngaphakathi, esinokuvulwa kuphela xa umnyango wokhuseleko uvaliwe.7.Ngezibuko lokubona i-DOP, igeyiji yoxinzelelo olwakhelwe ngaphakathi olwakhelwe ngaphakathi.
