Qhov sib txawv tseem ceeb ntawm Erlenmeyer flask thiab Florence flask yog tias Erlenmeyer flask muaj cov duab conical, whereas Florence flask muaj ib puag ncig.
Flaks yog cov khoom siv iav tseem ceeb hauv cov chaw sim los ntsuas cov kua dej ntau. Ob qho tib si Erlenmeyer flasks thiab Florence flasks yog ob lub khob iav uas peb siv los ua kua. Erlenmeyer lub raj mis yog lub raj mis kuaj uas muaj cov duab conical thiab lub hauv qab tiaj tus, thaum lub khob Florence yog ib lub raj mis kuaj nrog lub cev puag ncig thiab lub caj dab ntev, muaj npe tom qab lub nroog Florence.
Erlenmeyer Flask yog dab tsi?
Erlenmeyer flask yog lub raj mis kuaj uas muaj cov duab conical thiab lub tiaj tiaj. Nws yog hom titration flask uas tseem ceeb hauv kev ua titration. Hauv titrations, lub hwj yog muab tso rau hauv qab burette. Erlenmeyer flask feem ntau muaj cov tshuaj ntsuam xyuas ntawm titration. Tsis tas li ntawd, lub khob dej no tau raug hu ua tus kws tshawb fawb Emil Erlenmeyer tom qab nws tsim xyoo 1860.
Daim duab 01: Erlenmeyer Flask
Cov duab ntawm lub hwj Erlenmeyer sib txawv hauv nws lub hauv paus thiab hauv nws cov phab ntsa. Erlenmeyer flasks txawv ntawm beakers nyob rau hauv lawv lub cev tapered thiab nqaim caj dab. Peb tuaj yeem tsim cov raj mis no nyob ntawm daim ntawv thov, piv txwv li, siv iav lossis yas. Tsis tas li, tuaj yeem muaj ntau qhov ntim hauv cov khob no.
Qee zaum, lub qhov ncauj ntawm Erlenmeyer lub hwj muaj ib daim di ncauj, uas yog qhov tseem ceeb hauv kev npog. Peb kuj tseem tuaj yeem npog lub qhov ncauj tau yooj yim siv lub khob hauv av lossis lwm qhov txuas.
Buchner flask yog qhov muab los ntawm Erlenmeyer lub hwj thiab tseem ceeb hauv lub tshuab nqus tsev. Sab nraub qaum thiab lub caj dab nqaim ntawm Erlenmeyer lub raj mis yog qhov tseem ceeb hauv kev sib xyaw thiab swirling khoom hauv lub khob yam tsis muaj kev puas tsuaj loj. Tsis tas li ntawd, lub raj mis no yog tsim rau boiling kua. Thaum lub sij hawm boiling, qhov kub vapor condenses nyob rau sab sauv ntawm lub hwj, uas yuav pab kom txo tau qhov hnyav poob. Ntxiv mus, lub caj dab nqaim ntawm lub raj mis no tso cai rau lub funnel tso rau saum nws.
Florence Flask yog dab tsi?
Florence flask yog ib hom kev sim lub raj mis nrog lub cev puag ncig, lub caj dab ntev, thiab lub tiaj tiaj, muaj npe tom qab lub nroog Florence. Lub thawv no muaj txiaj ntsig zoo los tuav cov kua dej. Cov iav tshwj xeeb no yog tsim los rau cua sov, boiling, thiab distillation, nrog rau yooj yim swirling. Muaj ntau lub thicknesses rau iav kom tiv taus kev siv sib txawv. Txawm li cas los xij, nws feem ntau yog tsim los ntawm borosilicate iav rau lub hom phiaj ntawm cua sov thiab tshuaj tiv thaiv.
Daim duab 02: Florence Flask
Ib tsoos Florence flask tsis muaj iav hauv av sib koom ua ke ntawm caj dab ntev. Tab sis nws yuav muaj me ntsis di ncauj los yog flange nyob ib ncig ntawm lub caj dab. Tsis tas li ntawd, qhov ntim ib txwm peb tuaj yeem ntsuas siv cov iav no yog 1 liter.
Qhov txawv ntawm Erlenmeyer Flask thiab Florence Flask yog dab tsi?
Peb feem ntau siv lub hwj Erlenmeyer thiab Florence hwj thaum tuav cov kev sim nrog cov kua. Qhov sib txawv tseem ceeb ntawm Erlenmeyer flask thiab Florence flask yog tias Erlenmeyer flask muaj cov duab conical, whereas Florence flask muaj ib puag ncig. Erlenmeyer flasks tuaj ntau qhov sib txawv thiab ntim thaum Florence flasks feem ntau tuaj yeem tuav txog 1 liter. Ntxiv mus, Erlenmeyer flasks yog siv rau titrations, whereas Florence flasks yog pab tau rau cua sov, boiling, distillation, mixing, thiab lwm yam.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Erlenmeyer flask thiab Florence flask nyob rau hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Erlenmeyer Flask vs Florence Flask
Qhov sib txawv tseem ceeb ntawm Erlenmeyer flask thiab Florence flask yog lawv cov duab; Erlenmeyer flask muaj ib tug conical zoo thiab ib tug ca hauv qab, thaum Florence flask muaj ib puag ncig zoo thiab ib tug ntev caj dab nrog ib tug ca hauv qab. Ob qho tib si Erlenmeyer flasks thiab Florence flasks yog ib qho tseem ceeb heev nyob rau hauv titrations thiab lwm yam kua-koom nrog tshuaj thwmsim nyob rau hauv lub laboratory.
