Kuaj hlab

Cov hlab ntsha kuaj yog cov cuab yeej tseem ceeb hauv cov chaw kuaj mob thoob plaws ntau yam kev qhuab qhia. Los ntawm chemistry mus rau biology, cov thawv cylindrical no yog qhov tseem ceeb rau kev tuav, sib tov, thiab cov khoom cua sov.

Hom Kev Xeem Tubes

1. Standard Test Tubes

Standard test tubes feem ntau yog ua los ntawm iav los yog yas. Lawv yog siv los tuav thiab ua kom sov me me ntawm cov kua lossis cov khoom khib nyiab. Lawv cov qauv tsim muaj qhov sib npaug hauv qab thiab ncaj, ua rau lawv yooj yim los ntxuav thiab txo cov khoom poob thaum hloov tsheb.

• khoom siv: iav los yog yas
• siv: Kev ua haujlwm hauv chav kuaj dav dav, suav nrog kev sib xyaw thiab cov khoom siv cua sov

2. Kab lis kev cai

Kab lis kev cai raj feem ntau yog siv rau hauv cov chaw kuaj kab mob lom rau cog cov kab mob, cov nroj tsuag, lossis cov ntaub so ntswg me me. Cov raj no feem ntau tau nruab nrog lub hau npog ruaj ntseg lossis lub kaw lus kom tiv thaiv kev sib kis.

• khoom siv: Borosilicate iav los yog yas
• siv: Kev cog qoob loo thiab khaws cia cov qauv lom neeg

3. NMR Tubes

Nuclear Magnetic Resonance (NMR) raj yog cov raj tshwj xeeb uas siv hauv NMR spectroscopy. Cov raj no raug tsim los ua kom ntseeg tau tias lawv tsis cuam tshuam nrog cov hlau nplaum thaum tshawb xyuas.

• khoom siv: Cov iav zoo
• siv: NMR spectroscopy

Daim ntawv thov ntawm Test Tubes

Cov hlab ntsha kuaj tau siv ntau yam kev siv hauv chav kuaj, suav nrog:

• Tshuaj Reactions: Cov hlab ntsha kuaj yog qhov zoo tagnrho rau kev ua cov tshuaj tiv thaiv me me, tshwj xeeb tshaj yog hauv kev tshuaj xyuas zoo.
• Qauv Cia: Kab lis kev cai raj nrog stoppers feem ntau yog siv rau ib ntus cia cov qauv hauv chaw kho mob thiab kev tshawb fawb.
• Gas Collection: Hauv kev sim xws li electrolysis, cov hlab ntsha tuaj yeem siv los sau thiab soj ntsuam cov pa roj.
• Culturing Organisms: Kab lis kev cai raj yog qhov tseem ceeb hauv microbiology rau kev loj hlob thiab kawm cov kab mob nyob rau hauv kev tswj xyuas.

Cov kev coj ua zoo tshaj plaws rau kev siv cov kav raj

1. xaiv

• Xaiv cov khoom tsim nyog (iav lossis yas) raws li cov khoom siv tshuaj lom neeg ntawm cov khoom koj ua haujlwm nrog.
• Siv borosilicate iav rau kev siv cua sov kom tsis txhob tawg.

2. tuav

• Siv cov racks tsim nyog, clamps, los yog tus ntiv tes tuav kom ruaj ntseg, tshwj xeeb tshaj yog thaum cua sov.
• Daim ntawv xeem cov raj kom meej kom tsis txhob muaj kab mob sib kis.

3. Ntxuav

• Ntxuav cov raj kom huv si tom qab siv nrog cov kuab tshuaj uas tsim nyog lossis cov tshuaj detergents.
• Rau kev ua kom tsis muaj menyuam, autoclave iav kuaj cov raj raws li kev soj ntsuam raws tu qauv.

4. Kev Nyab Xeeb

• Ib txwm hnav cov cuab yeej tiv thaiv tus kheej (PPE) thaum tuav cov raj ntsuas, tshwj xeeb tshaj yog thaum cua sov lossis cuam tshuam nrog cov khoom phom sij.

Hais txog Cov Lus Nug

Dab tsi yog qhov txawv ntawm lub raj kuaj thiab lub raj kab lis kev cai?

Lub raj tshuaj ntsuam xyuas yog lub thawv ntim khoom siv dav dav, hos lub raj kab lis kev cai tshwj xeeb yog tsim los rau kev loj hlob thiab kawm txog kab mob lom.

Kuv yuav xaiv lub raj zoo li cas rau kuv qhov kev sim?

Xav txog cov khoom, qhov loj me, thiab lub hom phiaj. Rau cov tshuaj tiv thaiv, xaiv cov iav kuaj cov raj; rau kev ua haujlwm lom neeg, kab lis kev cai raj nrog kev kaw tsim nyog yog qhov zoo tagnrho.

xaus

Cov hlab ntsha kuaj yog ntau yam thiab cov khoom tseem ceeb hauv txhua qhov chaw kuaj. Nkag siab txog ntau hom thiab lawv cov ntawv thov tuaj yeem txhim kho koj cov kev sim hauv chav kuaj. Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws rau kev xaiv, tuav, thiab kev nyab xeeb, koj tuaj yeem ua kom muaj txiaj ntsig zoo thiab nyab xeeb kev ua haujlwm.
