Taug kev mus rau hauv feem ntau cov organic chemistry labs - seb nws puas yog lub tsev kawm ntawv qhia chaw, ib qho chaw tsim khoom hauv tsev, lossis chaw kuaj xyuas zoo ntawm cov nroj tsuag tshuaj - thiab feem ntau koj yuav pom qhov teeb meem tib yam li ntawm tsib feeb. Nws tsis yog cov reagent. Nws tsis yog SOPs ntawm phab ntsa. Nws yog cov rooj tog tuav txhua yam ua ke. Los yog ntau dua, cov rooj tog uas maj mam poob rau hauv cov xwm txheej nws yeej tsis tau tsim los daws.
Yog li ua ntej kev soj ntsuam tom ntej, tom ntej nyob ze - nco, lossis tom ntej corrosion- cov cuab yeej hais txog sau- tawm, nws tsim nyog nug: Puas yog koj lub chaw kuaj sim tsim ua rau cov organic chemistry ua haujlwm?
Qhov Tiag Pain Points Tsis muaj leej twg them nyiaj rau
Organic chemistry nyuaj rau txhua yam nws kov. Koj tab tom cuam tshuam nrog cov kuab tshuaj tsis haum xws li acetone, ethanol, thiab dichloromethane txhua hnub. Koj tab tom khiav cov tshuaj tiv thaiv uas tsim cov kua qaub vapors, cov pa taws ua pa, thiab qee zaus, cua sov ntau. Cov tshuaj ib puag ncig hauv ib qho chaw kuaj organic yog qhov ua phem tiag tiag - thiab cov rooj tog zaum hauv chav kuaj feem ntau tsuas yog tsis ntsuas rau nws.
Corrosion yog tus tua qeeb
Hlau- cov rooj zaumyam tsis muaj tshuaj lom neeg tsim nyog -cov tshuaj tiv thaiv kab mob pib oxidizing lub sij hawm hnyav hnyav ua ntu zus. Laminate ua hauj lwm nto npuas thiab delaminate los ntawm kev sib cuag ntev nrog cov kuab tshuaj organic. Thaum lub rooj zaum saum npoo degrades, nws dhau los ua qhov kev pheej hmoo kis kab mob, tsis yog qhov muag pom xwb. Cov thawj coj hauv chav kuaj feem ntau tsis pom qhov kev puas tsuaj mus txog thaum nws tau muab tso rau hauv lawv cov peev nyiaj.
Fume exposure yog underestimated
Muaj ntau lub labs tso siab rau ib leegfume hoodtso rau ntawm ib phab ntsa, tom qab ntawd cia siab tias cov neeg ua haujlwm nqa cov reagents qhib thoob plaws hauv chav los siv nws. Qhov tshwm sim tiag tiag tshwm sim hauv kev thauj mus los - thiab hauv cov chaw sim uas qhov cua tsis tau tsim rau hauv cov rooj tog zaum ntawm qhov pib. Lub qhov dej - kev sib xyaw fume hood tsis yog ib lub thawv nrog lub sash; nws xav tau kev tshem tawm cov cua kom zoo, cov tshuaj tiv thaiv kab mob sab hauv, thiab kev tso kawm uas phim cov haujlwm tiag tiag, tsis yog qhov chaw muaj phab ntsa xwb.
Reagent cia yog qhov tsis sib xws
Organic labs khaws cov nplaim taws, oxidizers, thiab corrosives nyob rau hauv lub rooj ntev zaum, ntawm cov txee qhib, thiab sab hauv -cov khoom siv lub hom phiaj uas muab xoom cais. Qhov no tsis yog kev tsis saib xyuas - feem ntau nws yog qhov chaw cia khoom uas tsis muaj lub hom phiaj - ua rau kev cais tshuaj lom neeg hauv thawj qhov chaw. Thaum flammables zaum ntawm oxidizers vim tias tsis muaj lwm qhov los muab lawv, qhov ntawd yog teeb meem rooj tog, tsis yog teeb meem ntawm cov neeg ua haujlwm.
Lub Hom Phiaj Dab Tsi -Ua Lab Furniture Hloov tiag tiag
Qhov kev kho tsis nyuaj, tab sis nws yuav tsum tau kho cov rooj tog hauv chav kuaj raws li kev ua haujlwm ruaj ntseg tsis yog qhov chaw ua haujlwm ntawm lub cev xwb.
Lab lub rooj zaumrau organic chemistry yuav tsum muaj epoxy resin los yog phenolic resin ua hauj lwm qhov chaw - ob leeg tiv thaiv tshuaj tua kab mob, tshav kub, thiab noo noo zoo dua li cov txheej txheem laminate. Cov ncej yuav tsum tau hmoov-coated los yog stainless siv, thiab hauv qab - lub rooj zaum qhov chaw yuav tsum tau tsim nrog cua nyob rau hauv lub siab, tsis retrofitted li cia.
Fume hoodsyuav tsum tau ua kom haum rau qhov ntim thiab hom chemistry tau ua. Ib lub chaw kuaj mob uas siv cov kuab tshuaj rho tawm txhua hnub muaj qhov xav tau sib txawv ntawm huab cua ntau dua li ib qho ua qee zaus acid digestions. Hood interiors lined nrog polypropylene lossis epoxy-coated steel kov cov tshuaj lom neeg tsis muaj degrading - uas tseem ceeb rau kev ua neej ntev thiab kev tswj kom huv si, tsis muaj paug huab cua.
Dedicated chemical cia txee- tsis yog tsuas yog lub thawv xauv khoom nkaus xwb - nrog cov khoom sib cais rau cov nplaim hluav taws, cov khoom corrosives, thiab oxidizers hloov pauv qhov kev pheej hmoo ntawm lub chaw kuaj mob loj heev. Tus kheej-kaw hinges, qhov cua qhov chaw nres nkoj, thiab spill- puag ncig tsis zoo-rau-muaj; lawv yog dab tsi cais cov khoom raws li kev lav phib xaub.
Kab hauv qab
Organic chemistry labs tsis ua tsis tiav kev kuaj xyuas kev nyab xeeb vim tias tsis zoo chemistry. Lawv ua tsis tiav vim lub cev ib puag ncig tsis tau teev tseg los txhawb cov chemistry ua tiav. Tau txais txoj cai ntawd pib ua ntej thawj reagent puas tau xaj - nws pib nrog cov rooj tog spec. Thiab qhov ntawd yog kev sib tham tsim nyog muaj thaum ntxov.
