Lub Lab Stopcock ua haujlwm li cas?
Lab stopcock yog ib qho cuab yeej siv los tswj cov pa roj lossis cov kua dej hauv chav kuaj. Nws muaj ib lub tog raj kheej tapered nrog ib tug threaded plug uas yuav tig mus qhib los yog kaw lub tog raj kheej. Lub stopcock ua hauj lwm ntawm lub hauv paus ntsiab lus ntawm ib tug threaded sib koom ua ke, uas tsim ib tug foob ntawm lub plug thiab lub tog raj kheej thaum nws tig. Plug thiab lub tog raj kheej. Lub plug yog ib tug tapered pas nrig nrog ib tug threaded nto uas haum rau lub tapered lub tog raj kheej. Thaum lub ntsaws yog tig, nws txav mus rau hauv lub tog raj kheej, hloov qhov loj ntawm qhov qhib ntawm lub ntsaws thiab lub tog raj kheej. Qhov no tso cai rau tus neeg siv los tswj cov roj lossis cov kua dej uas tuaj yeem dhau los ntawm qhov chaw nres tsheb. Lub stopcock feem ntau yog ua los ntawm iav lossis yas, cov ntaub ntawv uas tiv taus ntau yam tshuaj thiab tuaj yeem ntxuav tau yooj yim. Lub threaded sib koom ntawm lub ntsaws thiab lub tog raj kheej tsim ib lub kaw ntom ntom uas tiv thaiv kom tsis txhob ntws los yog nchuav. Lub ntsaws tuaj yeem tig tau siv lub ciaj ntswj lossis tus yuam sij, uas feem ntau ua rau hauv lub stopcock nws tus kheej. Ib qho ntawm qhov zoo ntawm lub lab stopcock yog nws qhov tseeb. Cov threaded sib koom ua ke tso cai rau kev tswj xyuas meej txog kev ntws ntawm cov pa roj lossis cov kua dej, uas yog qhov tseem ceeb hauv ntau daim ntawv thov kev sim. Lub stopcock tuaj yeem hloov kho kom tso cai rau cov kua dej kom dhau mus, uas yog tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev sim uas yuav tsum tau ceev faj ntsuas qhov ntim lossis cov nqi ntws. Zoo li txhua yam khoom siv hauv chaw kuaj mob, lub chaw soj nstcock yuav tsum tau siv nrog ceev faj kom tsis txhob muaj xwm txheej lossis raug mob. Lub stopcock yuav tsum tau ua tib zoo saib xyuas kom tsis txhob poob los yog tawg nws, thiab cov xov sib txuas yuav tsum tau kuaj xyuas cov dej xau ua ntej siv. Kev tu thiab tshuaj xyuas ntawm lub stopcock tsis tu ncua tuaj yeem pab xyuas kom meej tias nws tseem ua haujlwm thiab muaj kev nyab xeeb rau kev siv.
Lab Stopcocks puas tuaj yeem siv nrog cov tshuaj corrosive?
Lab stopcocks, tseem hu ua av iav stopcocks, yog cov cuab yeej siv hauv chav kuaj tseem ceeb siv los tswj cov dej ntws hauv cov hlab iav xws li cov raj mis, funnels, thiab condensers. Thaum lub chaw soj nstcocks feem ntau siv nrog cov tshuaj tsis muaj corrosive, lawv tuaj yeem siv nrog cov tshuaj corrosive nyob rau hauv qee yam mob. Thaum siv cov tshuaj tua kab mob nrog cov tshuaj corrosive, nws yog ib qho tseem ceeb uas yuav tau xaiv cov ntaub ntawv uas haum rau cov tshuaj siv. Borosilicate iav stopcocks feem ntau haum rau feem ntau cov tshuaj uas tsis yog-corrosive tab sis tej zaum yuav tsis haum rau cov tshuaj corrosive heev. Nyob rau hauv cov ntaub ntawv no, nws raug pom zoo kom siv stopcocks ua los ntawm chemically inert cov ntaub ntawv xws li PTFE (Teflon) los yog yas. PTFE stopcocks yog tshwj xeeb tshaj yog zoo-tsim rau corrosive tshuaj vim lawv kub tsis kam thiab tshuaj inertness. Kev tsim qauv ntawm lub chaw soj nstcocks tuaj yeem cuam tshuam rau lawv qhov tsim nyog rau kev siv tshuaj corrosive. Stopcocks nrog cov iav hauv av tej zaum yuav muaj kev cuam tshuam rau cov tshuaj tua kab mob ntau dua li cov stopcocks nrog cov npoo du, tsis ntxeem tau. PTFE stopcocks, piv txwv li, muaj ib tug du, tsis-porous nto uas yog resistant rau tshuaj tua kab mob thiab muaj peev xwm tiv taus kub thiab corrosive tshuaj. Cov tshuaj corrosive tuaj yeem ua rau muaj zog heev, thiab tswj qhov kub thiab txias yog qhov tseem ceeb rau kev nyab xeeb thiab raug kev sim. Nws yog ib qho tseem ceeb los saib xyuas qhov kub ntawm cov tshuaj corrosive thiab ib puag ncig ib puag ncig kom ntseeg tau tias qhov kub thiab txias nyob hauv qhov tsim nyog rau cov tshuaj siv. Thaum siv cov tshuaj tua kab mob nrog cov tshuaj corrosive, nws yog ib qho tseem ceeb kom ua raws li kev tiv thaiv kev nyab xeeb kom tsis txhob muaj kev phom sij. Ib txwm hnav cov cuab yeej tiv thaiv tus kheej tsim nyog, xws li hnab looj tes, tsom iav, thiab lub tsho tiv no, thiab ua haujlwm hauv qhov chaw muaj cua zoo. Tsis txhob kov cov tawv nqaij thiab qhov muag nrog cov tshuaj corrosive, thiab ua raws li cov txheej txheem pov tseg kom raug.
Lab stopcocks yog ib qho cuab yeej siv hauv chaw kuaj mob los tswj cov pa roj lossis kua dej. Lawv feem ntau yog siv ua ke nrog lwm yam khoom siv hauv chav kuaj, xws li cov raj mis, beakers, thiab kab. Thaum stopcocks tsis yog feem ntau siv rau kev xaiv hnyav hauv chromatography, lawv tuaj yeem ua lub luag haujlwm hauv tag nrho cov txheej txheem ntawm chromatography. Chromatography yog cov txheej txheem siv rau kev sib cais thiab txheeb xyuas qhov sib xyaw ntawm cov tebchaw. Nws tso siab rau lub hauv paus ntsiab lus uas sib txawv tebchaw muaj sib txawv affinities rau ib tug mobile theem thiab ib tug nyob twj ywm theem. Hauv cov kua chromatography, cov theem mobile yog cov kua hnyav uas nqa cov qauv los ntawm cov theem nyob ruaj khov, uas feem ntau yog cov khoom lossis cov kua uas txhawb nqa ntawm cov khoom. Kev xaiv hnyav yog ib feem tseem ceeb ntawm chromatography, vim nws tuaj yeem cuam tshuam rau kev sib cais ntawm cov tebchaw hauv cov qauv. Qhov kev xaiv ntawm cov kuab tshuaj yuav nyob ntawm seb qhov xwm txheej ntawm cov qauv thiab cov tebchaw yuav tsum tau sib cais. Feem ntau, cov kuab tshuaj yuav tsum muaj qhov tsim nyog polarity thiab boiling point rau txoj kev sib cais siv. Thaum stopcocks tsis yog feem ntau siv rau kev xaiv hnyav hauv chromatography, lawv tuaj yeem ua lub luag haujlwm hauv tag nrho cov txheej txheem. Piv txwv li, ib qho stopcock tuaj yeem siv los tswj cov dej ntws ntawm cov theem ntawm lub xov tooj ntawm tes los ntawm cov theem nyob ruaj khov hauv ib kem. Qhov no tso cai rau kev tswj xyuas meej ntawm cov txheej txheem sib cais, uas tuaj yeem yog qhov tseem ceeb rau kev ua kom pom kev sib cais ntawm cov tebchaw hauv cov qauv. Tsis tas li ntawd, stopcocks tuaj yeem siv los qhia cov qauv mus rau theem mobile. Piv txwv li, ib lub stopcock tuaj yeem siv los txuas lub hwj uas muaj cov qauv mus rau ib kem, tso cai rau cov qauv coj mus rau theem ntawm lub xov tooj ntawm tes thiab nqa mus rau theem nyob ruaj khov rau kev sib cais. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev xaiv ntawm cov kuab tshuaj rau chromatography yuav nyob ntawm ntau yam, nrog rau qhov xwm ntawm tus qauv, txoj kev sib cais siv, thiab qhov xav tau kev sib cais. Thaum stopcocks tuaj yeem ua lub luag haujlwm hauv tag nrho cov txheej txheem ntawm chromatography, lawv yuav tsum tsis txhob cia siab rau kev xaiv hnyav. Hloov chaw, kev xaiv cov kuab tshuaj yuav tsum tau ua raws li kev soj ntsuam kom zoo ntawm cov kev cai sib cais thiab cov khoom ntawm cov qauv.
