Lub raj mis Erlenmeyer, muaj npe tom qab nws tus neeg tsim khoom, German chemist Richard Lub Yim Hli Carl Emil Erlenmeyer, yog ib qho khoom siv hauv chaw soj ntsuam. Nws qhov txawv conical zoo thiab lub caj dab nqaim tau ua rau nws tseem ceeb rau ntau yam kev sim tshuaj lom neeg thiab kev sim tshuaj lom neeg. Txawm li cas los xij, kev taw qhia ntawm lub vented Erlenmeyer flask tau ntxiv txhim kho nws cov kev siv ntau yam thiab kev siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj tiv thaiv uas yuav tsum tau tswj los yog tso pa tawm ntawm cov pa roj.
Richard Erlenmeyer, tus xibfwb ntawm chemistry ntawm University of Heidelberg, tau tsim lub raj mis Erlenmeyer thaum xyoo pua 19th. Nws lub hom phiaj tseem ceeb yog los pab txhawb kev sib xyaw thiab cua sov ntawm cov tshuaj tiv thaiv, tshwj xeeb tshaj yog cov uas muaj cov tshuaj tsis haum. Lub raj mis conical zoo tso cai rau kom zoo dua nplawm thiab sib tov, thaum lub caj dab nqaim tiv thaiv splashing thiab evaporation. Tau ntau xyoo, tus qauv tsim tau hloov kho me me, tab sis cov yam ntxwv tseem ceeb tseem tsis tau hloov pauv.
Kev taw qhia txog cov yam ntxwv ntawm qhov cua hauv Erlenmeyer flasks yog ib qho kev hloov tshiab tsis ntev los no. Qhov xav tau rau qhov cua tshwm sim hauv kev sim qhov twg cov pa roj tau tsim los yog siv, xws li hauv cov txheej txheem fermentation lossis cov tshuaj tiv thaiv nrog cov roj. Ib txwm Erlenmeyer flasks, tsis muaj qhov cua, tuaj yeem ua rau lub siab lossis lub tshuab nqus tsev, uas tuaj yeem ua rau muaj kev tawg lossis tawg. Yog li ntawd, cov kws tshawb fawb thiab cov kws tsim qauv tsim cov vented Erlenmeyer flasks kom muaj kev nyab xeeb tswj lub siab tsim thiab tso cov pa roj thaum muaj kev cuam tshuam.
Tsim thiab Qauv

Tus tsim ntawm lub vented Erlenmeyer flask combines cov tsoos nta ntawm Erlenmeyer hwj nrog ntxiv venting mechanisms. Lub raj mis khaws nws cov yam ntxwv conical zoo thiab lub caj dab nqaim, uas muab qhov chaw sib xyaw kom txaus thiab tiv thaiv evaporation.
Lub venting feature feem ntau yog nyob rau sab saum toj ntawm lub caj dab, tso cai rau cov pa roj kom dim thaum tiv thaiv cov kua los ntawm spilling. Vented Erlenmeyer flasks muaj nyob rau hauv ntau qhov ntau thiab tsawg, xws li me me, 50-milliliter flasks siv nyob rau hauv kev kawm ntawv mus rau loj, 5-liter flasks siv nyob rau hauv industrial-scale cov tshuaj tiv thaiv. Lawv kuj yog tsim los ntawm ntau yam ntaub ntawv, xws li iav, yas, thiab stainless hlau.
Cov iav iav yog nyiam rau ntau daim ntawv thov vim lawv cov tshuaj inertness thiab pob tshab, uas tso cai rau kom yooj yim soj ntsuam cov tshuaj tiv thaiv. Cov hnab yas yog sib dua thiab tsis yooj yim dua, ua rau lawv haum rau kev ua haujlwm lossis chaw kawm. Stainless hlau flasks yog siv nyob rau hauv high-temperature los yog high-pressure cov tshuaj tiv thaiv, raws li lawv muaj peev xwm tiv taus huab cua. |
Function thiab Mechanism
Lub luag haujlwm tseem ceeb ntawm lub vented Erlenmeyer lub raj mis yog muab lub thawv muaj kev nyab xeeb thiab siv tau zoo rau cov tshuaj tiv thaiv uas tsim lossis haus cov pa roj. Lub tshuab ua pa tso cai rau cov pa roj kom dim yam tsis muaj kev tsim siab, uas tuaj yeem ua rau muaj kev phom sij txaus ntshai. Nws kuj tseem tiv thaiv lub khob los ntawm imploding yog tias lub tshuab nqus tsev tsim thaum lub sij hawm cov tshuaj tiv thaiv.
Lub tshuab cua tshuab tuaj yeem ua tau yooj yim li ib lub qhov ntawm lub caj dab ntawm lub khob, npog nrog lub xoob-fitting plug lossis paj rwb. Tsis tas li ntawd, nws tuaj yeem ua tau zoo dua li lub valve uas tso cai rau kev tswj xyuas meej ntawm cov roj ntws. Qee lub vented flasks tau nruab nrog lub siab nyem li qub uas qhib tau yog tias lub siab hauv lub khob siab tshaj qhov pib.
Lub vented Erlenmeyer lub hwj kuj yog tsim los tiv thaiv kev nruj ntawm kev ua haujlwm hauv chav kuaj. Nws yog tsim los ntawm cov khoom siv ruaj khov uas tuaj yeem tiv taus qhov kub thiab txias, tshuaj lom neeg, thiab kev ntxhov siab. Lub raj mis nqaim caj dab tiv thaiv kev txaws thiab evaporation, kom ntseeg tau tias cov tshuaj tiv thaiv ua haujlwm zoo thiab ua tau zoo.
Cov ntawv thov hauv Kev Tshawb Fawb
Lub vented Erlenmeyer flask muaj ntau yam kev siv hauv ntau yam kev tshawb fawb, suav nrog chemistry, biology, physics, thiab engineering.
