Ntxuav Petri tais diavyog cov txheej txheem tedious, tab sis cov txheej txheem no tuaj yeem ua rau kev sim ua tau zoo dua.Yog tias lub tais petri tsis tau ntxuav, tus kws sim yuav tsum tau nkim sijhawm ntau ua cov ntaub ntawv sim.Thiab yog tias lub tais petri raug ntxuav kom huv si, tus kws sim tuaj yeem ua qhov kev sim tau zoo dua.
Kev ntxuav ntawm Petri tais diav:
Feem ntau, nws mus txog plaub kauj ruam ntawm soaking, txhuam, pickling, thiab tu.
1. Soaking: Tshiab los yog siv khob iav yuav tsum tau tsau rau hauv dej ua ntej kom muag muag thiab yaj cov ntaub ntawv txuas.Cov iav tshiab yuav tsum tsuas yog txhuam nrog cov kais dej ua ntej siv, thiab tom qab ntawd tsau ib hmos hauv 5% hydrochloric acid;siv cov iav iav feem ntau muaj cov protein ntau thiab cov roj txuas rau nws, uas tsis yooj yim rau ntxuav tom qab ziab, yog li nws yuav tsum tau muab tso rau hauv dej huv tam sim ntawd tom qab siv txhuam.
2. Kev txhuam hniav: Muab cov khob ntim dej tso rau hauv cov tshuaj ntxuav tes thiab txhuam nws ntau zaus nrog txhuam txhuam.Tsis txhob tso tseg qhov chaw tuag thiab tiv thaiv kev puas tsuaj rau qhov chaw tiav ntawm cov tais diav.Ntxuav thiab qhuav cov iav ntxuav kom qhuav.
3. Pickling: Pickling yog kom ntub cov tais diav saum toj no hauv cov tshuaj ntxuav, tseem hu ua kua qaub, kom tshem tawm cov khoom seem seem ntawm cov tais diav los ntawm qhov muaj zog oxidation ntawm cov kua qaub.Pickling yuav tsum tsis pub tsawg tshaj li rau teev, feem ntau thaum hmo ntuj lossis ntev dua.Ceev faj nrog cov tais diav.
4. Yaug: Cov tais diav tom qab txhuam thiab pickling yuav tsum tau muab yaug nrog dej.Txawm hais tias cov tais diav tau muab yaug kom huv si tom qab pickling ncaj qha cuam tshuam rau kev vam meej lossis tsis ua tiav ntawm kab lis kev cai ntawm tes.Ntxuav cov tais diav tom qab ntxuav, thiab txhua lub tais yuav tsum tau rov "dej-ntws-dej" tsawg kawg yog 15 zaug, thiab thaum kawg soaked hauv ob-distilled dej rau 2-3 zaug, qhuav los yog qhuav, thiab ntim rau tom qab siv.

Txoj kev ntxuav ntawm kev siv XPZLaboratory glassware washerlos ntxuav lub tais petri:
Ntxuav kom muaj nuj nqis: 168 petri tais diav tuaj yeem ntxuav hauv ib pawg
Lub sij hawm ntxuav: 40 feeb kom ua tiav kev ntxuav
Cov txheej txheem ntxuav: 1. Muab cov tais petri los ntxuav (qhov tshiab tuaj yeem muab tso ncaj qha rau hauv lub raj mis ntxhua khaub ncaws, thiab lub tais petri nrog kab lis kev cai nruab nrab yuav tsum nchuav tawm ib qho loj ntawm kab lis kev cai nruab nrab kom ntau li ntau tau) rau hauv lub pob tawb sib xws. ntawm lub raj mis washer.Ib txheej tuaj yeem ntxuav 56 petri tais diav, thiab ib zaug tuaj yeem ntxuav 168 peb txheej petri tais diav.
2. Kaw lub qhov rooj ntawm lub raj mis lub tshuab ntxhua khaub ncaws, xaiv qhov kev pab cuam ntxuav, thiab lub tshuab yuav pib ntxuav.Cov txheej txheem tu muaj xws li kev ntxuav ua ntej - alkali lub ntsiab ntxuav - acid neutralization - dej ntshiab.
3. Tom qab ntxuav, lub qhov rooj ntawm lub tshuab ntxhua khaub ncaws yuav qhib, tshem tawm cov kab lis kev cai huv huv, thiab txav mus rau cov khoom siv kom tsis muaj menyuam kom tsis muaj menyuam.
Kev ntxuav ntawm petri tais diav hauv cov chaw sim tshuaj lom neeg yog ib feem tseem ceeb ntawm kev tswj xyuas hauv chav kuaj.Siv lub tshuab ntxhua khaub ncaws tsis siv neeg lub raj mis es tsis siv phau ntawv ntxuav tuaj yeem tiv thaiv kev sib kis los ntawm kev cuam tshuam cov ntaub ntawv sim, tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm sim, thiab txhim kho kev sim ua haujlwm.
