BSC Class II Type A2 Biological Safety Txee

Chav Kawm II Hom A2/B2 Biological Safety Txee

chav kuaj kev nyab xeeb txee / chav kawm ii lom kev nyab xeeb txee yog tsim nyog nyob rau hauv animalcule lab, tshwj xeeb tshaj yog nyob rau hauv tus mob

Thaum koj taug kev mus rau hauv chav kuaj kev tshawb fawb, muaj ib qho khoom siv uas feem ntau raug xa mus los ntawm ntau lub npe: cell culture hood, tissue culture hood, laminar flow hood, PCR hood, clean bench, or biosafety txee.Ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, yog tias tsis yog tag nrho cov "hoods" no yog tsim sib npaug;Qhov tseeb, lawv muaj peev xwm tiv thaiv sib txawv heev.Cov xov zoo sib xws yog tias cov cuab yeej muab laminar cua ntws rau thaj chaw ua haujlwm "huv", tab sis nws yog ib qho tseem ceeb kom paub tias tsis yog txhua yam cuab yeej muab cov neeg ua haujlwm ntxiv lossis kev tiv thaiv ib puag ncig.Biosafety txee (BSCs) yog ib hom khoom siv biocontainment siv hauv cov khoom siv roj ntsha. Laboratories los muab cov neeg ua haujlwm, ib puag ncig, thiab kev tiv thaiv cov khoom.Feem ntau BSCs (piv txwv li, Chav Kawm II thiab Chav Kawm III) siv cov khoom siv hluav taws xob ua haujlwm siab (HEPA) cov lim dej hauv ob qho tib si cov pa thiab cov khoom siv los tiv thaiv kev cuam tshuam rau biohazards.

Lub Txiaj Ntsig Kev Nyab Xeeb Kev Nyab Xeeb (BSC), tseem hu ua Biosafety Txee feem ntau yog siv los tuav cov kab mob lom kab mob lossis rau cov ntawv thov uas xav tau thaj chaw ua haujlwm tsis muaj menyuam.Lub txee kev nyab xeeb lom neeg tsim cov cua nkag thiab qis qis uas muab kev tiv thaiv tus neeg teb xov tooj.

Lub txee kev nyab xeeb lom neeg (BSC) yog thawj qhov kev tswj xyuas engineering siv los tiv thaiv cov neeg ua haujlwm tiv thaiv biohazardous los yog kis kab mob thiab pab tswj kev tswj cov khoom siv tau ua haujlwm nrog thaum nws lim cov cua nkag thiab tso pa tawm.Nws yog qee zaum hu ua laminar ntws los yog cov ntaub so ntswg kab lis kev cai hood.xav tau kev tiv thaiv kev ntsuas, xws li tshuaj, khw muag tshuaj, kev tshawb fawb tshawb fawb thiab lwm yam.

Biosafety txee (BSC), tseem hu ua biosafety txee, yog lub hood lossis hnab looj tes lub thawv tsim nyog rau kev nyab xeeb thiab siv cov qauv tshuaj lom neeg, cov kab mob, cov kab mob sib kis, xws li COVID-19, thiab qee yam tshuaj paub ua rau mob qog noj ntshav ( carcinogens) los yog yug tsis xws luag (teratogens).Cov txheej txheem kev nyab xeeb ntawm cov khoom siv roj ntsha yog txhais los ntawm Cov Qib Kev Nyab Xeeb Kev Nyab Xeeb (BSL), uas sib txawv kev noj qab haus huv thiab kev nyab xeeb ntawm Chav Kawm 1, Chav Kawm 2, thiab Chav Kawm 3, thiab Chav Kawm 4 ib puag ncig.

Chav Kawm II Biological Safety Txee systems muab ob qho tib si HEPA lim cua thiab HEPA lim cua tawm.Chav kawm-2 biosafety txee yuav tsum muaj nyob rau hauv muaj cov kab mob me me, xws li Staphylococcus aureus.Class-2 biosafety sub-types muaj xws li A1, A2, B1, B2, thiab C1 configuration.Chav Kawm II A2 biosafety txee recirculate 70% ntawm cov huab cua rov qab mus rau hauv qhov chaw ua hauj lwm thaum tso tawm qhov seem 30%.Chav Kawm II B2 biosafety txee tam sim ntawd tso tawm 100% ntawm huab cua tawm hauv thaj chaw ua haujlwm.Chav Kawm II C1 biosafety txee yog NSF / ANSI 49 pom zoo thiab muaj peev xwm toggling ntawm A2 thiab B2 teeb tsa.

Biosafety Cabinets (BSC), tseem hu ua Biological Safety Cabinets, muab cov neeg ua haujlwm, cov khoom, thiab kev tiv thaiv ib puag ncig los ntawm laminar airflow thiab HEPA pom rau biomedical / microbiological lab.

Chav Kawm II A2 biological kev nyab xeeb txee / lom kev nyab xeeb txee chaw tsim khoom lub ntsiab lus:

1. Cov ntaub thaiv kab hlau rhuav tshem tawm tiv thaiv kev sib kis sab hauv thiab sab nraud, 30% ntawm cov huab cua ntws tawm tawm sab nraud thiab 70% ntawm kev ncig sab hauv, tsis zoo siab ntsug laminar ntws, tsis tas yuav nruab cov kav dej.

2. Lub qhov rooj iav tuaj yeem txav tau nce thiab nqis, tuaj yeem ua haujlwm tsis txaus ntseeg, yooj yim rau kev khiav lag luam, thiab tuaj yeem raug kaw kom tsis muaj menyuam, thiab qhov chaw qhov siab txwv lub tswb nrov.

3. Lub qhov hluav taws xob tso zis hluav taws xob hauv qhov chaw ua haujlwm yog nruab nrog lub qhov (socket) tsis muaj dej thiab cov dej phwj tuaj cuam tshuam los muab kev yooj yim rau tus neeg teb xov tooj.

4. Ib lub lim dej tshwj xeeb raug ntsia ntawm cov pa tawm kom tswj tau cov pa phem.

5. Qhov chaw ua haujlwm yog ua los ntawm cov khoom zoo 304 stainless hlau, uas yog du, seamless, thiab tsis muaj qhov kawg.Nws tuaj yeem yooj yim thiab huv si ntxuav thiab tuaj yeem tiv thaiv kev yaig ntawm cov neeg ua haujlwm corrosive thiab tshuaj tua kab mob.

6. Nws txais yuav LED LCD vaj huam sib luag tswj thiab built-in UV teeb tiv thaiv ntaus ntawv, uas tsuas yog qhib tau thaum lub qhov rooj ruaj ntseg kaw.

7. Nrog DOP nrhiav chaw nres nkoj, built-in sib txawv siab ntsuas.

8, 10 ° qaij lub kaum sab xis, nyob rau hauv txoj kab nrog tib neeg lub cev tsim lub tswv yim
