Ceramics tsis yog ntxeem tau thiab tsis nqus dej, uas ua rau lawv zoo tagnrho rau kev sim uas yuav tsum tau muaj kev tswj hwm qhov chaw noo noo. Ceramic tais kuj tseem tiv taus cov tshuaj thiab cov cua sov, ua rau lawv haum rau kev siv kub. Txawm li cas los xij, cov tais diav ceramic hnyav dua thiab tsis yooj yim dua li cov tais diav yas lossis iav thiab yuav tsum tau ceev faj kom tsis txhob muaj kev puas tsuaj. Ntxiv nrog rau cov khoom siv, tus qauv tsim ntawm Petri phaj kuj tuaj yeem sib txawv nyob ntawm qhov kev xav tau tshwj xeeb ntawm kev sim. Piv txwv li, qee qhov Petri tais diav muaj lub hauv qab conical los pab txhawb kev sau cov kua khib nyiab, thaum lwm tus muaj lub hauv qab tiaj tus rau niaj hnub culturing. Lub hau ntawm Petri phaj kuj tuaj yeem sib txawv hauv kev tsim, nrog rau qee qhov muaj lub hau kaw ntom ntom kom tiv thaiv kev sib kis, thaum lwm tus muaj lub hau xoob kom tso cai rau kev sib pauv roj.
Dab tsi yog Qhov Loj ntawm Petri Dishes?
Petri cov tais diav yog cov khoom tseem ceeb hauv cov chaw sim tshawb fawb, siv rau cov kab lis kev cai ntawm tes, kab lis kev cai kab mob, thiab lwm yam txheej txheem tshawb fawb. Lawv tuaj hauv ntau qhov ntau thiab tsawg kom haum rau ntau hom kev sim. Cov no yog qhov tsawg tshaj plaws ntawm Petri cov tais diav thiab feem ntau yog siv rau kev sim me me, xws li kev coj tus kab mob los yog kuaj tshuaj tua kab mob. Lawv tuaj yeem tuav tau txog li 3-5 mL ntawm cov xov xwm thiab yog qhov zoo tagnrho rau siv hauv microbiology labs. Cov no yog me ntsis loj dua 30mm cov tais diav thiab feem ntau yog siv rau cov kab lis kev cai ntawm tes thiab lwm cov txheej txheem kev tshawb fawb uas yuav tsum muaj thaj tsam loj dua. Lawv tuaj yeem tuav tau txog li 10-15 mL ntawm cov xov xwm thiab yog qhov zoo rau kev siv hauv cell culture labs. Cov no yog cov tais loj dua 50 hli thiab feem ntau yog siv rau cov kab lis kev cai ntawm tes, kab lis kev cai kab mob, thiab lwm yam kev tshawb fawb uas yuav tsum tau muaj thaj tsam loj dua. Lawv tuaj yeem tuav tau txog li 20-25 mL ntawm cov xov xwm thiab yog qhov zoo tagnrho rau siv hauv microbiology thiab cell culture labs. Cov no yog cov tais diav loj dua 60 hli thiab feem ntau yog siv rau cov kab lis kev cai ntawm tes, kab lis kev cai kab mob, thiab lwm yam kev tshawb fawb uas yuav tsum tau muaj thaj tsam loj dua. Lawv tuaj yeem tuav tau txog li 30-35 mL ntawm cov xov xwm thiab yog qhov zoo rau siv hauv microbiology thiab cell culture labs. Cov no yog qhov loj tshaj plaws ntawm Petri cov tais diav thiab feem ntau yog siv rau cov kab lis kev cai ntawm tes, kab lis kev cai kab mob, thiab lwm yam kev tshawb fawb uas yuav tsum tau muaj thaj tsam loj. Lawv tuaj yeem tuav tau txog li 50-60 mL ntawm cov xov xwm thiab yog qhov zoo tagnrho rau siv hauv microbiology thiab cell culture labs. Thaum xaiv Petri phaj loj, nws yog ib qho tseem ceeb uas yuav tau xav txog tus nqi ntawm cov qauv koj xav tau rau kab lis kev cai thiab cov tais diav uas koj yuav tsum tau ua ib zaug. Cov tais diav loj tuaj yeem ua tau raws li cov qauv ntau dua tab sis yuav siv tau ntau qhov chaw hauv lub incubator. Tsis tas li ntawd, qhov luaj li cas ntawm lub hau tuaj yeem cuam tshuam rau kev xaiv ntawm Petri tais, vim qee qhov kev sim xav tau lub hau nruj kom tswj tau cov mob anaerobic.
Yuav Ua Li Cas Petri Dishes Yuav Sterilized?
Autoclaving yog txoj kev siv ntau tshaj plaws rau kev ua kom tsis muaj menyuam cov tais diav. Nws suav nrog nthuav tawm cov tais diav rau qhov kub thiab txias hauv chav ua noj autoclave chamber. Thaum tshav kub kub thiab chav tua los yog tshem tawm tag nrho cov kab mob thiab lawv cov spores ntawm lub tais petri. Autoclaving yog tsim rau sterilizing yas, iav, thiab ceramic petri tais diav.
Kev ua kom tsis muaj tshuaj lom yog siv cov tshuaj tua kab mob los yog tshem tawm cov kab mob hauv lub tais petri. Txoj kev no tsis zoo li autoclaving thiab tsuas yog pom zoo thaum autoclaving tsis ua tau lossis siv tau. Cov tshuaj sterilizers feem ntau siv xws li glutaraldehyde, hydrogen peroxide, thiab ethylene oxide. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias qee cov tshuaj tuaj yeem tso cov khoom seem ntawm lub tais petri, uas tuaj yeem cuam tshuam rau kev loj hlob ntawm cov kab mob.
Radiation sterilization siv hluav taws xob ionizing, xws li gamma rays los yog electron beams, los tua los yog tshem tawm cov kab mob los ntawm cov tais diav petri. Txoj kev no tsis yog siv los ua kom tsis muaj menyuam cov tais diav vim yog tus nqi siab thiab cov cuab yeej tshwj xeeb yuav tsum tau ua. Txawm li cas los xij, nws yog ib txoj hauv kev zoo rau sterilizing cov ntaub ntawv kub-rhiab heev.
Qhuav cua sov kom tsis muaj menyuam muaj feem cuam tshuam cov tais diav petri kom kub hauv qhov cub cua kub. Txoj kev no yog tsim rau iav thiab ceramic petri tais diav tab sis tsis pom zoo rau cov tais diav yas, vim tias cov cua sov tuaj yeem ua rau lawv yaj los yog distort.
Petri Dishes puas siv tau rau kev kuaj tshuaj?
Yog lawm, petri tais tuaj yeem siv rau kev kuaj tshuaj. Qhov tseeb, lawv feem ntau siv rau hauv cov chaw soj nstuam tshawb fawb rau lub hom phiaj no. Petri tais diav yog ib hom iav los yog yas tais siv nyob rau hauv lub chaw soj nstuam rau cell kab lis kev cai, kab lis kev cai kab mob, thiab lwm yam scientific txheej txheem. Lawv yog cov tiaj tiaj, ncig cov tais diav nrog me ntsis nkhaus hauv qab uas tsim ib lub foob thaum lub hau raug nias, ua rau lawv zoo tagnrho rau kev siv hauv cov txheej txheem kuaj tshuaj. Petri cov tais diav feem ntau yog siv rau kev kuaj tshuaj tiv thaiv kab mob. Lawv muaj cov khoom noj khoom haus agar, ib yam khoom uas muab cov as-ham rau kev loj hlob ntawm cov kab mob, thiab tom qab ntawd inoculated nrog cov kab mob. Tom qab ntawd cov tshuaj ntxiv rau hauv lub tais, thiab cov kab mob tau pom zoo rau kev loj hlob. Qhov no yuav pab txiav txim siab qhov ua tau zoo ntawm cov tshuaj hauv inhibiting cov kab mob loj hlob. Petri tais kuj siv rau kev kuaj toxicology. Lawv tuaj yeem sau nrog cov kab lis kev cai ntawm tes thiab tom qab ntawd raug rau cov tshuaj sib txawv lossis tshuaj lom neeg. Tom qab ntawd cov hlwb raug soj ntsuam rau kev hloov pauv ntawm tus cwj pwm, xws li kev hloov pauv hauv morphology lossis kev hloov pauv hauv cell proliferation. Qhov no yuav pab txiav txim seb cov tshuaj lom los ntawm cov tshuaj los yog tshuaj nyob rau hauv lub hlwb. Petri tais diav yog siv rau cov txheej txheem tshuaj xyuas tshuaj. Lawv tau ntim nrog cov khoom noj khoom haus thiab tom qab ntawd inoculated nrog cov kab mob. Tom qab ntawd cov tshuaj ntxiv rau hauv lub tais, thiab cov kab mob tau pom zoo rau kev loj hlob. Qhov no yuav pab txiav txim siab qhov ua tau zoo ntawm cov tshuaj hauv inhibiting cov kab mob loj hlob thiab tuaj yeem siv los tshuaj xyuas cov tshuaj tua kab mob tshiab lossis lwm yam tshuaj uas yuav muaj peev xwm kho tau. Petri tais kuj siv rau kev tshawb fawb pharmacokinetic. Lawv tuaj yeem sau nrog cov kab lis kev cai ntawm tes thiab tom qab ntawd raug rau cov tshuaj sib txawv ntawm qhov sib txawv. Cov hlwb tom qab ntawd raug soj ntsuam rau kev hloov pauv ntawm tus cwj pwm, xws li kev hloov pauv hauv cell proliferation lossis hloov pauv hauv cell metabolism. Qhov no yuav pab txiav txim seb cov tshuaj no absorbed, metabolized, thiab excreted los ntawm lub hlwb.
