Qhov sib txawv tseem ceeb ntawm burette thiab pipette yog nyob rau hauv lawv cov txheej txheem tso tawm. Burettes muaj lub stopcock nyob rau hauv qab thaum lub pipette muaj ib tug dropper zoo li lub kaw lus uas tso kua rau hauv qhov xav tau los ntawm kev txo lub nqus tsev vacuum.
Burette thiab pipette yog ntsuas cov cuab yeej uas peb siv hauv chemistry labs, kom faib cov kua hauv qhov ntsuas. Cov no yog cov cuab yeej zoo tshaj plaws uas peb tuaj yeem siv los ntxiv cov kua tshuaj kua qaub rau cov txheej txheem titration.
Burette yog dab tsi?
Lub burette yog lub iav lub tog raj kheej uas ntev thiab qhib rau sab saum toj nrog lub nres nres rau hauv qab kom tsis txhob muaj cov kua ntim hauv nws tawm ntawm lub burette. Lub raj muaj cov cim ntim kom tso cai rau tus neeg siv tsuas yog siv cov kua ntau npaum li qhov xav tau hauv cov txheej txheem tshuaj lom neeg tshwj xeeb.
Daim duab 01: Daim duab ntawm ib tug Burette
Ntxiv mus, muaj cov burettes sib txawv uas tso cai rau peb siv cov kua sib txawv. Yog tias koj siv 5 ml burette thiab tso kua hauv cov tee los ntawm kev tso cov stopcock, tus nqi siv yog txiav txim siab los ntawm kev rho tawm qhov kawg nyeem ntawm burette ntawm 5 ml.
Pipette yog dab tsi?
Ib lub pipette yog lub cuab yeej kuaj; peb feem ntau siv nws hauv chemistry, biology thiab tshuaj thauj cov kua ntsuas ntsuas, feem ntau yog cov khoom siv xov xwm. Hauv qee ceg ntawm kev kawm xws li molecular biology thiab analytical chemistry, peb yuav tsum tau muab cov kua dej tsawg tsawg. Hauv qhov kev sim siab no, muaj cov khoom siv uas pab kom faib cov kua ntau npaum li peb xav tau. Ib qho khoom siv zoo li no uas muab kev tswj hwm tag nrho yog pipette. Nws zoo li siv lub koob txhaj tshuaj hauv chav kuaj; yog li no, peb kuj hu nws ua ib tug tshuaj dropper.
Daim duab 02: Plastic Pipette
Yog li ntawd, pipettes yog ib qho tseem ceeb kom muaj qhov tseeb thiab ua haujlwm zoo hauv kev cuam tshuam nrog cov kua me me. Peb siv ob qho tib si micropipettes thiab macro pipettes hauv chav kuaj. Ntxiv mus, peb tuaj yeem siv micropipettes rau cov kua me me (1- 1000 micro liters). Pipettes ua haujlwm los ntawm kev tsim lub tshuab nqus tsev saum cov kua dej. Nws mam li tso cai rau tus neeg siv los nias kom xoob lub tshuab nqus tsev thiab faib cov kua dej uas xav tau.
Qhov txawv ntawm Burette thiab Pipette yog dab tsi?
A burette yog lub khob iav tiav nrog tus kais ntawm ib kawg, rau kev xa cov kua dej paub, tshwj xeeb tshaj yog nyob rau hauv titrations. Ntawm qhov tod tes, lub pipette yog ib qho cuab yeej kuaj uas siv hauv chemistry, biology, thiab tshuaj thauj cov kua ntsuas ntsuas, feem ntau ua cov khoom siv xov xwm. Yog li, qhov sib txawv tseem ceeb ntawm burette thiab pipette yog nyob rau hauv lawv cov txheej txheem tso tawm. Burettes muaj lub stopcock nyob rau hauv qab thaum lub pipette muaj ib tug dropper zoo li lub kaw lus uas tso kua rau hauv qhov xav tau los ntawm kev txo lub nqus tsev vacuum.
Tsis tas li ntawd, lub pipette yog me dua burette. Raws li lwm qhov sib txawv tseem ceeb ntawm burette thiab pipette, pipettes yog qhov tseeb dua hauv kev tso kua hauv cov khoom me dua burettes.
Cov duab hauv qab no ntawm qhov sib txawv ntawm burette thiab pipette qhia tag nrho cov kev sib txawv no hauv daim ntawv teev npe.
Summary – Burette vs Pipette
Ob lub burettes thiab pipettes yog cov cuab yeej tshuaj ntsuam xyuas. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm burette thiab pipette yog nyob rau hauv cov txheej txheem tso tawm. Yog li ntawd, burettes muaj lub stopcock nyob rau hauv qab thaum lub pipette muaj ib tug dropper zoo li ib tug system uas tso kua rau hauv qhov xav tau npaum li cas los ntawm txo lub nqus tsev vacuum.
