Taw qhia

Hauv cov chaw soj nstuam niaj hnub no, kev ua haujlwm precision tso qhov kev xav tau ntawm cov khoom siv. Tshwj xeeb tshaj yog thaum ua haujlwm nrog cov kua dej ntau, cov neeg ua haujlwm feem ntau ntsib nrog ntau yam kev cov nyom. Ib txwm siv labware, thaum tseem muaj txiaj ntsig hauv kev ua haujlwm niaj hnub, yog qhov loj thiab tsis meej thaum tuav cov kua me me, ua rau nws nyuaj rau kev ua kom tau raws li cov kev cai nruj rau kev ua kom huv thiab huv hauv kev sim cov xwm txheej.

Lub high-precision kawm tiav tsim ntawm me me ntim kawm tiav dropper lub raj mis ua kua dispensing ntau controllable thiab txhim khu kev qha.

Vim li cas lub Lab tsis tuaj yeem ua yam tsis muaj Me Me Kawm Tiav Burette Fwj?

Cov ntim me me uas kawm tiav burette fwj tau siv dav hauv cov chaw sim vim tias lawv nthuav tawm cov txiaj ntsig tshwj xeeb hauv cov ntsiab lus ntawm precision, kev nyab xeeb thiab kev ua haujlwm zoo.

1. Precision ntsuas muaj peev xwm

Kev rov ua dua thiab qhov tseeb ntawm kev sim yog nyob ntawm cov kua dej ntxiv. Cov raj mis tshwj xeeb muaj qhov ua yuam kev me me dua li cov ntim khoom kawm tiav thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev sim nrog kev tswj xyuas nruj ntxiv.

2. Kev tiv thaiv kev ua qias tuaj

Lub raj mis dropper yog tsim los nrog lub hau ntsaws ntsaws ruaj ruaj los yog ib lub taub ntim lub taub hau, uas txhim kho kev sib khi zoo thiab tiv thaiv cov ntsiab lus ntawm evaporating lossis oxidizing. Nyob rau tib lub sijhawm, piv rau kev ua haujlwm pipette uas yuav tsum tau hloov cov lus qhia tsis tu ncua, lub taub hau nws tus kheej zam ntau yam kev ua haujlwm thiab txo qhov muaj peev xwm ntawm kev sib kis, txhim kho kev ua haujlwm thiab txuag cov khoom siv.

3. Khoom siv kev nyab xeeb

Cov fwj kawm tiav peb muag yog ua los ntawm cov iav borosilicate siab, kub-resistant thiab corrosion-resistant, haum rau high-temperature kho los yog muaj zog acid thiab alkali reagents.

Hom Daim Ntawv Thov Scenarios

Cov ntim me me kawm tiav burette fwj tau dav siv hauv ntau qhov kev sim rau lawv qhov kev ua tau zoo thiab kev ua haujlwm yooj yim, tshwj xeeb tshaj yog rau kev sim ua haujlwm uas yuav tsum tau ua kom muaj kev tswj xyuas ua kua thiab kev ua haujlwm yooj yim.

1. Kev sim tshuaj molecular biology

Hauv kev ua haujlwm qib molecular, qhov loj thiab ntim ntawm reagents ncaj qha cuam tshuam cov txiaj ntsig ntawm kev sim. Dropper fwj yog qhov zoo tagnrho rau DNA / RNA rho tawm thiab khaws cia, thiab 1ml loj tuaj yeem tiv thaiv cov qauv evaporation thiab ua kom yooj yim rau hauv tub yees. Hauv kev ua haujlwm enzyme lossis tshuaj tiv thaiv kab mob, 3ml lub raj mis tuaj yeem siv los faib cov tshuaj reagents kom raug, zam kev poob ntawm kev ua haujlwm los ntawm kev rov ua kom khov thiab thawing ntawm lub fwj loj, thiab ua kom muaj kev rov tsim dua thiab ruaj khov ntawm kev sim.

2. Tshuaj ntsuam xyuas

Rau cov txheej txheem vial npaj hauv kev txheeb xyuas qhov ntau, 5 ml lub raj mis dropper muab qhov chaw rau kev soj ntsuam yooj yim thiab kev tswj xyuas thiab tsim nyog rau ntau theem dilutions. Rau qee yam tshuaj lom lossis tsis haum rau reagents, lub raj mis xau-pov thawj drip tip thiab sealing xov tsim ua tau zoo txhim kho kev tuav pov hwm kev nyab xeeb thiab txo cov kev pheej hmoo ntawm cov neeg ua haujlwm raug thiab roj vaporization.

3. Cov chav kuaj qhia

Hauv cov tsev kawm ntawv qib siab thiab cov tsev kawm ntawv theem nrab kev kuaj xyuas, kev xa tawm ua ntej reagent tuaj yeem tsis tsuas yog txo cov reagent pov tseg, tab sis kuj txo cov kev pheej hmoo ntawm cov tub ntxhais kawm kev sib cuag ncaj qha nrog cov tshuaj txaus ntshai thiab txhim kho kev kawm kev nyab xeeb. Lub raj mis pob tshab nrog cov nplais pab cov tub ntxhais kawm tsim kom muaj "kev nkag siab zoo" thiab "titration meej" kev paub, thiab txhim kho kev cob qhia ntawm kev sim.

Xaiv Phau Ntawv Qhia

Ntawm ntau hom thiab cov ntaub ntawv xaiv los ntawm, kev tshawb fawb thiab kev tsim nyog yuav khoom ntawm cov ntim me me kawm tiav lub raj mis yog qhov tseem ceeb los lav qhov kev ntseeg tau thiab kev nyab xeeb ntawm kev sim cov txiaj ntsig.

1. Muaj peev xwm xaiv logic

Opaque kev sim xav tau hais kom hloov lub raj mis qhov ntau thiab tsawg:

• 1 ml / 2 mlfwj yog tsim rau me me heev ib qho nqi reagents, txo cov khib nyiab thiab yooj yim cia.
• 3ml ibfwj yog qhov loj tshaj plaws thiab thoob ntiaj teb, haum rau kev sim txhua hnub hauv cov kua dispensing, nruab nrab muaj peev xwm thiab nqa tau yooj yim.
• 5ml iblub raj mis tsim nyog rau cov kev daws teeb meem tsis tu ncua, zam kev rov ua dua tshiab thiab txhim kho kev ua haujlwm ntawm kev sim.

2. Qhov tseem ceeb parameter tsom

Txoj kev xaiv yuav tsum tau tsom mus rau:

• Scale clarity: Lub raj mis zoo zoo yuav tsum tau laser etched los yog luam tawm nrog adhesion siab kom tsis txhob scale fading nyob rau hauv kub sterilization los yog tu thiab lav lub sij hawm ntev readability.
• Kev sib khi: Nws raug nquahu kom ua qhov kev sim hloov pauv yooj yim ua ntej kev yuav khoom thawj zaug - sau lub raj mis nrog dej, ntswj lub hau kom nruj thiab thim rov qab rau 24 teev los soj ntsuam seb puas muaj qhov tshwm sim los, uas yog siv los simulate qhov chaw cia.

3. Kev ceeb toom kom tsis txhob muaj teeb meem

Laboratory ib puag ncig muab kev xav tau siab ntawm cov khoom ntim khoom, thiab cov teeb meem hauv qab no yuav tsum tau crystalized:

• Lub raj mis yas tsis zoo yuav muaj cov yas yas lossis cov organic hnyav leachate, tshwj xeeb tshaj yog thaum khaws cov kua qaub los yog cov organic reagents, uas tej zaum yuav ua rau muaj kab mob, cuam tshuam rau purity thiab kev nyab xeeb ntawm kev sim.
• Cov khoom pheej yig nrog cov teeb meem loj loj tuaj yeem ua rau qhov tsis raug spiking ntim, uas tuaj yeem ua rau kev sim tsis zoo lossis rov ua tsis tiav, tshwj xeeb tshaj yog thaum tsim cov tshuaj tiv thaiv-rhiab heev.

Xaus

Cov fwj kawm tiav me me yog qhov tsis pom tseeb tab sis ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo thiab muaj txiaj ntsig ntawm chav kuaj. Los ntawm kev ntsuas qhov ntsuas qhov tseeb / kev ua tau zoo sealing zoo thiab cov khoom siv tshuaj lom neeg nyiam, lawv muab peb npaug lav ntawm "precision + kev nyab xeeb + ua haujlwm tau zoo" hauv kev sim ua haujlwm. Cov khoom siv yooj yim tab sis tseem ceeb no ua kom muaj kev ntseeg siab ntawm cov ntaub ntawv, kev ncaj ncees ntawm cov qauv, thiab kev rov tsim dua ntawm cov txheej txheem sim.

Cov kws sim yuav tsum xaiv lub peev xwm thiab cov khoom siv ntawm lub raj mis kom tsim nyog raws li kev sim ua haujlwm sib txawv txhawm rau txhawm rau txhim kho kev ua haujlwm tau zoo thiab zam kev tsis tsim nyog lossis kev pheej hmoo. Ib lub vial sib raug zoo yuav yog ib feem tseem ceeb ntawm kev ua tiav ntawm qhov kev sim.
