Thaum nws tuaj Laboratory iav, peb feem ntau tau nug cov lus nug los ntawm cov neeg siv khoom xws li: chav kuaj iav yog dab tsi? Yuav ua li cas pov tseg cov iav hauv chav kuaj? Dab tsi yog qhov chaw kuaj iav iav siv rau?
Yog li, peb yuav sim teb qee yam ntawm cov lus nug saum toj no thiab muab cov ncauj lus kom ntxaws, tab sis cov lus qhia yooj yim los pab koj nkag siab txhua yam koj xav paub txog chav kuaj iav.
Laboratory glassware yog dab tsi?
Laboratory glassware yog hais txog ntau yam khoom siv hauv kev tshawb fawb, thiab ib txwm ua los ntawm iav. Cov iav tuaj yeem raug tshuab, khoov, txiav, molded, thiab tsim rau ntau qhov ntau thiab tsawg, thiab yog li ntawd muaj nyob rau hauv chemistry, biology, thiab analytical laboratory. Ntau lub chaw soj nstuam muaj cov kev cob qhia los qhia seb cov iav siv li cas thiab ceeb toom thawj zaug rau cov neeg siv txog kev nyab xeeb kev nyab xeeb cuam tshuam nrog kev siv iav.
Laboratory glassware siv rau dab tsi?
Glassware tau ntev ua ib feem tseem ceeb ntawm cov chaw kuaj chemistry. Iav lub koob meej ntev tau tseem siab vim tias nws yog qhov tsis muaj zog, ruaj khov, yooj yim customizable, thiab pheej yig. Vim yog cov yam ntxwv zoo li no, iav tau siv los tsim ntau yam khoom siv. Kev tsis paub txog cov cuab yeej no tuaj yeem ua rau tsis meej pem, siv tsis raug thiab kev puas tsuaj. Yog li ntawd, kev nkag siab zoo ntawm glassware yog tsim nyog los xyuas kom meej kev nyab xeeb thiab ua tiav hauv chav kuaj.
Yog xav paub ntxiv txog kev siv cov iav iav, thov nyeem kab lus: Ntau tshaj 20 lub chaw kuaj mob uas lawv siv
yog vim li cas iav siv nyob rau hauv lub lab
Ib qho ntawm cov laj thawj tseem ceeb ntawm cov iav iav siv hauv cov chaw sim yog vim nws qhov ua haujlwm ntev thiab muaj peev xwm tiv taus cua sov, txias thiab lwm yam kev ua haujlwm nruj thaum sim. Qee hom iav muaj kev tiv thaiv ntau dua rau kev sim kev tshawb fawb ntau dua li lwm tus, xws li Pyrex®, hom iav tiv thaiv tshav kub uas tau siv los ntawm cov kws tshuaj. Lwm hom yog quartz iav, uas paub txog nws purity thiab qib siab ntawm visibility uas tshwm sim los ntawm nws. Iav kuj yog pob tshab, uas tuaj yeem ua rau nws yooj yim los soj ntsuam txhua yam uas tau kawm, thiab nws kuj tseem muaj zog, yog li nws muaj qhov tsis tshua muaj tshwm sim ntawm cov tshuaj.
Cov kua qaub twg yog siv los ntxuav cov iav hauv chav kuaj?
Cov kua qaub suav nrog aqua regia (ib qho sib xyaw ntawm nitric acid thiab hydrochloric acid), diluted sulfuric acid, chromic acid tov, piranha kua thiab fuming sulfuric acid yog siv los ntxuav cov chav kuaj iav, raws li University of Wisconsin Office of Chemical Safety.
Cov no yog cov khoom muaj txiaj ntsig thiab yuav tsum tau siv los ntawm cov tib neeg uas tau kawm txog lawv txoj kev siv kom raug thiab muaj cov khoom siv tiv thaiv tus kheej tsim nyog (PPE). WUBO pom zoo kom muaj lub luag haujlwm hnyav ua rau cov hnab looj tes tiv taus thiab tshuaj tiv thaiv kab mob, tiv thaiv qhov muag, cov tsho hauv qab thiab cov ntaub npog, thiab hais tias cov haujlwm yuav tsum tau ua hauv lub fume hood thaum tsim nyog.
Yuav ua li cas pov tseg cov iav hauv chav kuaj?
Cov iav iav yuav tsum tsis txhob muab pov tseg nrog cov thoob khib nyiab. Cov neeg ua haujlwm hauv tsev thiab lwm tus tau raug mob thaum nqa cov hnab khib nyiab nrog cov iav tawg hauv lawv.
Ntau qhov kev txiav los yog lacerations vim kev pov tseg tsis raug ntawm chav kuaj iav tsis ntev los no tau tshaj tawm hauv tsev kawm ntawv. Hauv kev sib zog los tshem tawm lossis txo qis cov kev raug mob no, qee cov txheej txheem yuav raug ua raws thaum muab cov iav tawg lossis tsis siv tau.
Cov iav tawg yuav tsum tau muab ntxuav tam sim ntawd. Lub chaw soj nstuam yuav tsum muaj ib qho txhuam me me thiab lub lauj kaub plua plav kom huv si tom qab muaj xwm txheej me me. Forceps lossis duct daim kab xev tuaj yeem siv los khaws cov khoom me me ntawm cov iav tawg.
Dab tsi koj yuav tsum paub:
Cov iav uas muab pov tseg yuav tsum muab tso rau hauv cov ntaub ntawv pov thawj me me, ob-kab kab los yog lub thawv tshwj xeeb tsim los pov tseg cov iav.
Lub thawv yuav tsum ruaj ntseg kaw nrog daim kab xev.
Txhua lub thawv ntawv tuaj yeem siv tau, yog tias nws ruaj khov thiab qhov loj me uas yuav tsis hnyav tshaj 40 phaus thaum puv.
Lub thawv yuav tsum tau sau npe raws li cov khoom.
- CAUTION LABORATORY GLASSWARE nkaus xwb!
- TSIS TXAUS SIAB ZOO, Tshuaj Kho Mob, PATHOLOGICAL WASTES lossis RADIOLOGICAL WASTES
- Koj yuav tsum tso lub thawv ncaj qha rau hauv lub DUMPSTER.
Tsis txhob cia Cov Kev Pab Cuam Tshuam los tswj cov iav tawg.
Tsis txhob siv lub thawv kuaj iav rau kev pov tseg
- Ntse
- Cov khoom siv biohazardous
- Cov dej khib nyiab
- Chemically contaminated laboratory glassware/plastics los yog yas-ware
- Cov thawv ntim tshuaj uas tsis tuaj yeem muab pov tseg raws li cov khoom pov tseg tsis tu ncua
