Lab iav Cuvette

Lab iav cuvette

Lab iav cuvette tau muab faib ua quartz khob, khob khob thiab khob yas raws li lawv cov ntaub ntawv. Raws li kev ntsuas sib txawv, muaj cov khob colorimetric thiab capillary colorimetric khob. Feem ntau, kev ntsuam xyuas ntawm nucleic acid thiab UV quantitative protein txais quartz khob lossis iav, tab sis nws tsis haum rau kev txiav txim siab colorimetric.

Nco ntsoov

Thaum siv lub cuvette, ob lub teeb xaim hluav taws xob yuav tsum ua tib zoo sib luag thiab muab tso rau hauv vertically hauv cuvette thav duab, txhawm rau xyuas kom meej tias qhov teeb meem teeb pom kev yog perpendicular rau lub teeb xaim nto thaum ntsuas, tsis txhob cuam tshuam lub teeb thiab xyuas kom ruaj. optical txoj kev.

(1) Thaum noj cov cuvette, koj tsuas tuaj yeem kov cov iav hauv av ntawm ob sab nrog koj cov ntiv tes kom tsis txhob tiv tauj qhov chaw kho qhov muag.

(2) Tsis txhob hu rau qhov chaw kho qhov muag nrog cov khoom tawv lossis av. Thaum muaj cov tshuaj, qhov siab tsuas yog 2/3 ntawm lub cuvette. Yog tias muaj cov kua dej seem nyob ntawm qhov chaw kho qhov muag, nws tuaj yeem maj mam adsorbed nrog cov ntawv lim, thiab tom qab ntawd so nrog daim ntawv lo ntsiab muag lossis lo lo ntxhuav.

(3) Tag nrho cov kev daws teeb meem uas muaj cov khoom uas corrode iav yuav tsum tsis txhob muab cia rau hauv lub cuvette ntev.

(4) Ntxuav lub cuvette nrog dej tam sim ntawd tom qab siv. Yog tias tsim nyog, soak hauv 1: 1 hydrochloric acid, thiab tom qab ntawd yaug nws nrog dej.

(5) Tsis txhob muab cov cuvette tso rau ntawm qhov cub lossis hluav taws xob rau cua sov lossis ci hauv qhov cub kom qhuav.

(6) Yog hais tias lub cuvette tsis txaus ntseeg thaum ntsuas, nws tuaj yeem kuaj pom ntawm nws tus kheej. Tus neeg siv tuaj yeem xaiv lub wavelength xya caum-xya.

Muab ib txheej ntawm cuvettes rau ntawm lub wavelength tiag tiag siv, txhaj cov dej distilled rau hauv lawv, kho qhov kev xa tawm ntawm ib qho ntawm lawv mus rau 95 feem pua ​​(teeb tsa cov cuab yeej digital rau 100%), thiab ntsuas qhov kis ntawm cov lwm tus. Yog tias qhov sib txawv ntawm kev xa tawm tsis ntau tshaj 0.5 feem pua, nws tuaj yeem siv ua ke.

Ntxuav txoj kev ntawm Lab iav cuvette:

(1) Feem ntau siv chromic acid ntxuav cov tshuaj yuav tsum tsis txhob siv los ntxuav lub cuvette, vim hais tias cov cuvette nrog dej qee zaum muaj cua sov hauv zos hauv cov tshuaj ntxuav, ua rau tawg ntawm qhov sib txuas ntawm cuvette thiab puas. Nyob rau tib lub sijhawm, cov cuvette ntxuav nrog cov tshuaj ntxuav yog zoo li yuav nyob twj ywm kab chromium, uas yog absorbed nyob rau hauv cheeb tsam ultraviolet, yog li nws yuav cuam tshuam rau kev txiav txim siab ntawm chromium thiab lwm yam ntsiab lus.

Nws feem ntau tau tawm tswv yim kom siv cov tshuaj sib xyaw ntawm nitric acid thiab hydrogen peroxide (5: 1) rau soak thiab ntxuav, thiab tom qab ntawd yaug nrog dej. Rau cov cuvette uas nyuaj rau kev ntxuav los ntawm txoj kev dav dav, ob txoj hauv qab no kuj tuaj yeem siv tau.

(2) Soak lub cuvette nyob rau hauv sodium carbonate (20g / L) tov uas muaj ib tug me me ntawm anionic surfactant, ntxuav nws nrog dej, thiab ces tsau nws nyob rau hauv lub mix ntawm hydrogen peroxide thiab nitric acid (5: 1) rau ib nrab ib teev. teev.

(3) So hauv lub fume hood nrog tov tov ntawm hydrochloric acid, dej thiab methanol (1: 3: 4).

QTswj kev tswj

Cov khoom zoo yog tsim, tsis kuaj. Qhov zais cia ntawm kev tswj hwm kev tsim khoom yog: cia txhua tus ua lawv tus kheej cov khoom. Cov neeg ua haujlwm yuav tsum tau ua kev tshuaj xyuas tus kheej ntawm cov khoom uas lawv tsim. Tsuas yog cov khoom uas lawv xav tias tsim nyog tuaj yeem ntws mus rau cov txheej txheem tom ntej lossis kev cob qhia. Cov khoom tsis tsim nyog pom hauv kev tshuaj xyuas tus kheej yuav tsum raug txheeb xyuas thiab muab tso rau nyias.

Los ntawm txoj kev, raws li ISO tus qauv, ntau lawm yog nruj me ntsis ua. Nrog kev tshuaj xyuas ua ntej shippment, xws li kev kuaj pom, Puncture resistance test, leak proof test, flexibility test, sterilization etc., tsuas yog high-quality thiab ISO dhau sampling hnab yuav raug xa mus rau cov neeg muas zaub.
