Kev tsis
A volumetric conical khob, tseem hu ua Erlenmeyer flask, yog ib qho tseem ceeb ntawm cov khoom siv hauv chav kuaj siv feem ntau rau kev sib xyaw, cua sov, thiab khaws cov kev daws teeb meem hauv chemistry thiab biology kuaj. Nws cov duab tshwj xeeb, tus cwj pwm los ntawm lub hauv paus dav tapering rau hauv lub caj dab nqaim, ua haujlwm ntau lub hom phiaj uas txhim kho nws cov txiaj ntsig hauv ntau yam kev sim teeb tsa.
Lub hauv paus dav ua kom muaj kev ruaj ntseg, tiv thaiv lub khob los ntawm tipping yooj yim, tshwj xeeb tshaj yog thaum tuav cov kua nplaum los yog bubbling. Qhov kev ruaj ntseg no tseem ceeb heev thaum lub sijhawm ua haujlwm xws li nplawm lossis cua sov, qhov kev tswj xyuas meej yog qhov tsim nyog kom tsis txhob muaj kev sib tsoo lossis kev sib tsoo. Lub caj dab nqaim, ntawm qhov tod tes, ua kom yooj yim nchuav thiab txo cov evaporation, yog li khaws cov kev ncaj ncees ntawm cov tshuaj.
Volumetric conical flasksfeem ntau yog tsim los ntawm cov khoom siv ruaj khov, pob tshab zoo li iav lossis yas, uas tso cai rau kev pom cov ntsiab lus yooj yim. Cov iav iav muaj cov tshuaj tiv thaiv zoo dua thiab qhov kub thiab txias, thaum xaiv cov yas muab kev yooj yim yuag thiab txo kev pheej hmoo ntawm kev tawg. Lawv feem ntau tuaj nrog kev kawm tiav uas tau cim rau ntawm lawv sab, ua kom muaj kev ntsuas meej ntawm cov kua ntim, uas yog qhov tseem ceeb rau kev npaj cov kev daws teeb meem tshwj xeeb.
Specifications
Daim ntawv thov
Qhov tseem ceeb tshaj plaws ntawm daim ntawv thov ntawm lub khob ntim ntim yog ntsuas thiab npaj cov kev daws teeb meem uas paub txog qhov tseeb. Los ntawm kev kos cov ntim tiav tiav ntawm lub khob, cov kws tshawb fawb tuaj yeem xyuas kom meej tias cov kua siv pes tsawg hauv lawv cov kev sim.
Hauv chemistry thiab biochemistry, ntim ntim ntim feem ntau yog siv los npaj cov qauv kev daws teeb meem, dilutions, thiab lwm yam kev daws teeb meem uas qhov tseeb yog qhov tseem ceeb. Piv txwv li, thaum npaj ib qho kev daws ntawm ib tug paub concentration, ib tug tej yam loj ntawm solute yog yaj nyob rau hauv ib tug volumetric hwj thiab ces diluted mus rau qhov xav tau ntim nrog ib tug hnyav.
Volumetric flasks kuj yog siv rau kev txhaj tshuaj thiab aliquoting, qhov twg me me, meej ntim ntawm cov tshuaj yog xav tau rau ntau yam kev sim lossis kev tshuaj xyuas. Qhov no ua kom muaj qhov sib xws thiab rov ua dua tshiab hauv cov txiaj ntsig kev sim.
Certified volumetric flasks, uas tau calibrated thiab txheeb xyuas qhov tseeb, yog siv nyob rau hauv analytical chemistry thiab lwm yam teb uas yuav tsum tau lub siab tshaj plaws precision. Cov flasks no feem ntau siv nyob rau hauv lub chaw soj nstuam uas yuav tsum tau ua raws li cov kev cai nruj.
Txawm hais tias tsis yog ib txwm ua lub khob hliav qab, ntim ntim ntim (hauv lawv daim ntawv cylindrical) qee zaum tuaj yeem siv los ua cov hlab ntsha sib xyaw kom sib xyaw ua ke thiab sib cais ntawm cov kuab tshuaj, tshwj xeeb tshaj yog thaum npaj cov kev daws teeb meem uas yuav tsum tau ceev faj tswj ntawm ntim thiab concentration.
Cov Lus Qhia Siv dav dav
Thaum siv lub khob ntim ntim, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem tuav kom tsis txhob muaj qhov yuam kev hauv kev ntsuas. Qhov no suav nrog kev yaug lub raj mis nrog cov kuab tshuaj uas yuav tsum tau siv, ntxiv cov kua dej thiab dissolving nws tag, thiab tom qab ntawd diluting mus rau qhov xav tau ntim ntawm lub khob.
Volumetric flasks feem ntau yog ua los ntawm iav los yog lwm yam ntaub ntawv uas yog resistant rau tshuaj thiab muaj tsawg permeability rau gases, kom ntseeg tau qhov tseeb thiab stability ntawm cov kev daws teeb meem nyob rau hauv lawv.
Hauv kev xaus, thaum lub sij hawm "volumetric conical khob" tej zaum yuav tsis xa mus rau ib qho tshwj xeeb, cov khoom siv hauv chav kuaj, cov hauv paus ntsiab lus thiab kev siv ntawm cov khoom ntim ntim feem ntau yog qhov tseem ceeb rau kev ntsuas cov kua dej meej, kev npaj cov tshuaj, thiab ua kom qhov tseeb thiab rov tsim dua tshiab ntawm cov txiaj ntsig kev sim hauv ntau yam kev tshawb fawb thiab kev lag luam.
Kev Npaj ntawm Kab lis kev cai Media
Kev npaj ntawm kab lis kev cai xov xwm hauv biochemistry yog txheej txheem tseem ceeb rau kev cog qoob loo thiab kev loj hlob ntawm cov kab mob, cov hlwb, thiab cov ntaub so ntswg hauv chav kuaj. Kab lis kev cai xov xwm muab cov khoom noj tseem ceeb, yam tseem ceeb ntawm kev loj hlob, thiab qee zaum cov xwm txheej tshwj xeeb tsim nyog los txhawb kev loj hlob thiab kev saib xyuas ntawm cov khoom lom neeg no.
Cheebtsam ntawm Culture Media
Carbon thiab Energy Sources: Cov no feem ntau suav nrog cov suab thaj yooj yim xws li qabzib, uas yog lub zog tseem ceeb rau kev loj hlob microbial.
Nitrogen Sources: Amino acids, peptides, proteins, thiab inorganic nitrogen tebchaw (piv txwv li, ammonium ntsev) yog muab los txhawb cov synthesis ntawm cov proteins thiab nucleic acids.
Inorganic ntsev: Minerals xws li phosphates, sulfates, thiab chlorides yog tsim nyog rau ntau yam biochemical cov tshuaj tiv thaiv thiab osmotic tshuav nyiaj li cas.
Vitamins thiab Growth Factors: Qhov tseem ceeb rau kev loj hlob ntawm qee cov kab mob, tshwj xeeb tshaj yog cov uas tsis tuaj yeem ua rau lawv tus kheej.
Dej: Cov dej huv huv yog lub hauv paus ntawm tag nrho cov kab lis kev cai xov xwm, kom ntseeg tau tias cov kab mob sib kis tau tsawg.
Buffers: Cov tshuaj zoo li sodium bicarbonate pab tswj pH tas li, uas yog qhov tseem ceeb rau kev loj hlob zoo.
Agar: Feem ntau ntxiv los ua tus neeg sawv cev solidifying los tsim cov khoom siv xov xwm, tso cai rau kev tsim cov colonies uas tuaj yeem pom tau yooj yim thiab cais tawm.
Cov kauj ruam npaj
Kev tsim qauv: Xaiv daim ntawv qhia tsim nyog raws li hom kab mob los yog cov kab mob ntawm tes. Qhov no suav nrog kev txiav txim siab qhov tseeb ntawm txhua yam khoom.
Ntsuas thiab ntsuas: Precisely ntsuas tag nrho cov khoom qhuav siv qhov sib npaug thiab hloov mus rau lub thawv huv, tsis muaj menyuam.
Dissolving: Ntxiv ib feem ntawm tag nrho cov dej uas xav tau thiab ua kom sov maj mam kom yaj cov khib nyiab kom tiav. stirring feem ntau yog tsim nyog los xyuas kom meej homogeneity.
Kev kho pH: Thaum yaj, kho cov pH mus rau qib uas xav tau siv cov kua qaub los yog cov hauv paus tsim nyog. Cov kauj ruam no yog qhov tseem ceeb vim tias txawm tias qhov sib txawv me ntsis tuaj yeem cuam tshuam kev loj hlob.
QS (Quality-Strength) Kev Xeem: Ib qho qauv me me tuaj yeem raug kuaj xyuas kom ntseeg tau tias cov xov xwm kawg yuav ua tau raws li cov qauv zoo, suav nrog pH, osmolarity, thiab cov ntsiab lus zoo.
Qhov kawg Volume Kho: Ntxiv cov dej ntxiv kom ncav cuag qhov kawg xav tau ntim.
Sterilization: Txoj kev siv ntau tshaj plaws yog autoclaving, uas suav nrog cua sov cov xov xwm kom kub siab (feem ntau yog 121 degree) nyob rau hauv siab rau lub sij hawm teev tseg los tua cov kab mob tam sim no.
Txias thiab Pouring: Tom qab ua kom tsis muaj menyuam, tso cai rau cov xov xwm kom txias rau qhov kub thiab txias (feem ntau nyob ib ncig ntawm 50 degree) ua ntej nchuav rau hauv cov tais diav uas tsis muaj kab mob los yog cov dej haus. Rau cov khoom siv xov xwm, agar yuav solidify thaum txias.
Cia: Ua kom raug kaw thiab sau npe, cov ntaub ntawv npaj yuav tsum muab cia rau hauv qhov chaw txias, tsaus kom txog thaum xav tau, kom ntseeg tau tias lawv nyob tsis muaj menyuam thiab hauv lawv lub txee-lub neej.
Kev txiav txim siab tshwj xeeb
Selective thiab Differential Media
Cov no muaj cov khoom tshwj xeeb tsim los txwv kev loj hlob ntawm qee yam kab mob thaum txhawb kev loj hlob ntawm lwm tus los yog tso cai rau kev sib txawv ntawm ntau hom kab mob raws li cov yam ntxwv pom.
Serum thiab lwm yam ntxiv
Qee cov xov xwm kab lis kev cai yuav tsum tau ntxiv cov ntshav, cov tshuaj hormones, lossis lwm yam tshuaj lom neeg los txhawb kev loj hlob ntawm cov kab mob nyuaj xws li cov tsiaj txhu.
Cov txheej txheem aseptic
Kev nruj nruj rau kev coj ua aseptic thaum lub sijhawm npaj tag nrho yog qhov tseem ceeb los tiv thaiv kev sib kis.
Lwm yam qauv tsim
Ntxiv mus, qhov du, nkhaus sab hauv qhov chaw txo qis qhov sib xyaw ntawm cov khoom seem, ua kom yooj yim los ntxuav thiab ua kom cov txiaj ntsig raug. Lub raj mis tsim kuj txhawb kev sib xyaw kom zoo, raws li lub caj dab nqaim pab ncaj qha swirling tam sim no tsim los ntawm nplawm rods los yog sib nqus stirrers rau hauv qab, kom ntseeg tau tias homogeneous daws.
Hauv cov ntsiab lus, covvolumetric conical khobyog ib qho khoom siv ntau yam, txhim khu kev qha hauv kev tshawb fawb thiab kev kawm, ua kom yooj yim rau kev ntsuas qhov tseeb, kev sib xyaw kom zoo, thiab kev nyab xeeb ntawm kev daws cov tshuaj lom neeg.
