Koj yuav tsum paub txog lub raj mis distillation. Nws yog lub khob ntim rau cov kua distillation lossis fractionation. Nws feem ntau yog siv nrog lub condenser, cov yeeb nkab ua kua, los yog kua adapter. Nws tseem tuaj yeem nruab nrog lub tshuab hluav taws xob roj. Kev ceev faj rau kev siv lub tshuab distillation. Asbestos mesh yuav tsum tau muab tso rau thaum cua sov,

Hauv kev tsom xam ua haujlwm, kev ntxhua khaub ncaws iav tsis yog tsuas yog npaj ua haujlwm ua ntej kev sim tab sis kuj yog kev ua haujlwm. Kev huv huv ntawm chav kuaj iav iav ncaj qha cuam tshuam rau qhov kev sim thiab txawm tias txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm qhov kev sim. Vim tias cov tais diav tsis huv lossis tsis huv, lawv feem ntau ua rau muaj kev sim loj, thiab txawm tias

Ua ntej, qhov yuam kev ntawm kev ntxuav cov iav iav 1. Kev ntxuav cov iav iav yog thawj kauj ruam hauv kev tshuaj ntsuam xyuas. Hauv kev xyaum, ntau tus neeg feem ntau tsis quav ntsej los ntxuav cov iav siv tam sim ua ntej thiab tom qab kuaj xyuas, lossis ntxuav cov khoom siv. Yog li ntawd, lub phab ntsa sab hauv ntawm lub cuab yeej yog hnyav heev

Laboratory ceev faj txog kev ua haujlwm 1. Nws yog txwv tsis pub noj thiab haus hauv chav kuaj. Ib tug neeg ib zaug tau noj ib yam dab tsi thaum saib lub tshuab tsom iav thiab haus cov tshuaj reagents nyob ze. Txawm hais tias nws yog qhov ceev kom ntxuav lub plab, nws yog qhov ua tsis taus pa. Nws tseem raug txwv tsis pub siv cov tshuaj reagents hauv chav kuaj ua "khoom noj khoom haus thiab tshuaj ntxiv", xws li

Ua ntej, dab tsi yog qhov cuam tshuam ntawm npuas hauv burette rau qhov kev xeem? 1. Yog tias muaj npuas thaum pib, nws yog qhov sib npaug ntawm cov kua dej ntau dua li qhov tseeb (vim tias cov roj tau txais kev txhawb nqa), yog li qhov ntim ntawm qhov kawg titration tov yog loj heev, thiab cov concentration ntawm cov khoom siv.

Lub raj mis volumetric yog ib qho khoom siv ntau. Yuav ua li cas txiav txim seb lub khob ntim ntim khoom puas tsim nyog? Cia peb muab ib daim ntawv yooj yim rau txhua tus kom txhua tus tuaj yeem txiav txim tau yooj yim seb lub khob ntim khoom puas tsim nyog. Koj tuaj yeem sau lub thawv nrog dej thiab kos nrog qhov sib npaug. Tus qauv muaj peev xwm ntawm lub raj mis muaj peev xwm

Cov kua ntxhua khaub ncaws, hu ua detergent lossis tshuaj pleev, feem ntau yog siv rau cov iav iav uas tsis yooj yim rau txhuam nrog txhuam, xws li burettes, pipettes, volumetric flasks, retorts, thiab lwm yam. Nws kuj yog siv rau ntxuav crapware uas tsis tau siv rau. ntev thiab fouling uas txhuam tsis tuaj yeem ntxuav. Txoj cai

Lub burette yog ib qho tseem ceeb ntawm cov iav ntim khoom hauv cov chaw kuaj mob, tsim los rau cov titration thiab ntsuas cov kua, kom ntseeg tau qhov tseeb hauv kev sim tshuaj. Cov khoom siv tseem ceeb: Lub chaw kuaj burette yog dab tsi? Lub Laboratory Burette yog cov iav ntim ntim siv los xa cov kua dej tsis raug. Nws yog ua los ntawm ib tug slender thiab uniform iav raj nrog

1 、 Muaj peb yam hauv tag nrho. (1) Kev ntsuas ntsuas nrog cov khoom hnyav thiab cov hlab ntsha ntsuas cov tshuaj ntim (2) Cov txheej txheem kev daws teeb meem muaj peev xwm titration (3) Cov ntsuas ntsuas kom raug txiav txim siab qhov kawg ntawm qhov kawg. Muaj plaub pawg, acid-base titration, complexometric titration, redox titration, thiab nag lossis daus titration. Txoj kev acid-base titration yog ib txoj kev tsom xam titration raws li

Nyob rau hauv rooj plaub koj xav tau cov ntaub ntawv lossis muaj kev tsis ntseeg, thov hu rau WUBOLAB, lub chaw tsim khoom iav iav.
