Cov ntsuas ntsuas no yog tsim tshwj xeeb los ntsuas cov tshuaj pleev cov khaub ncaws ua haujlwm ntawm cov ntaub acid thiab alkali tshuaj.
1. Semi-cylindrical plexiglass pob tshab tank, nrog lub taub sab hauv ntawm (125 ± 5) hli thiab ntev ntawm 300 hli.
2. Qhov txoj kab uas hla ntawm kev txhaj koob hno lub qhov txhaj tshuaj yog 0.8mm; Lub koob ntxig yog tiaj.
3. Tsis siv neeg txhaj tshuaj, txuas ntxiv txhaj tshuaj ntawm 10ml reagent nyob rau hauv 10s.
4. Tsis siv neeg sijhawm thiab lub tswb; LED Zaub Zaum Xeem Sijhawm, Qhov tseeb 0.1s.
5. Fais fab mov: 220Vac 50Hz 50W
GB24540-2009 "Cov khaub ncaws tiv thaiv" acid-paus tshuaj tiv thaiv khaub ncaws "
1. Txiav ib daim ntawv plaub lim thiab cov yeeb yaj kiab pob tshab txhua tus nrog qhov loj ntawm (360 ± 2) hli × (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (235 ± (23 5) mm.
2. Tso lub siab tawv pob tshab rau rau hauv lub tshuab pob tshab tank, npog nws nrog daim ntawv lim, thiab ua raws li ib leeg. Ceevfaj tsis txhob tawm ib qho khoob lossis pob, thiab ua kom pom tias qhov kawg ntawm cov duab sib cav sib ceg, thiab cov ntawv lim dej yog dej ntws yaug.
3. Tso cov qauv ntawm cov ntawv lim kom ntev ntawm cov qauv yog mus rau sab zawj, thiab sab nraud ntawm tus qauv yog 30mm dhau ntawm qhov kawg ntawm qhov zawj. Xyuas cov qauv kom zoo kom paub tseeb tias nws cov nplaim hluav taws xob nruj nrog cov ntawv lim, tom qab ntawd kho cov qauv ntawm cov pob tshab zoo nkauj nrog ib qho pob tshab flastent nrog ib qho pob tshab nrog lub clampent.
4. Hnov qhov hnyav ntawm lub beaker me me thiab sau nws li M1.
5. Muab cov beaker me me hauv qab cov kab xev kom ntseeg tau tias txhua tus reagents ntws los ntawm saum npoo ntawm cov qauv tuaj yeem sau tau.
6. Paub meej tias lub sijhawm ntsuas "lub sijhawm" Timer ntaus ntawv ntawm lub vaj huam sib luag tau teem rau 60 vib nas this (cov qauv yuav tsum tau).
7. Nias lub "fais fab hloov" ntawm lub vaj huam sib luag mus rau "1" txoj hauj lwm kom tig mus rau lub zog ntsuas.
8. Npaj cov reagent kom thiaj li txhaj koob txhaj tau ntxig rau hauv lub reagent; Nias lub "aspirate" khawm ntawm lub vaj huam sib luag, thiab qhov ntsuas yuav pib khiav rau kev xav.
9. Tom qab cov kev ntshaw ua tiav, tshem tawm cov khaub ncaws reagent; Nias lub "txhaj" ntawm lub vaj huam sib luag, qhov ntsuas yuav cia li txhaj tshuaj tiv thaiv, thiab lub sijhawm ntsuas "sijhawm" yuav pib sijhawm; Kev txhaj tshuaj tiav tom qab 10 vib nas this.
10. Tom qab 60 vib nas this, lub suab nrov yuav ceeb toom, qhia tias qhov kev xeem tiav.
11. Coj mus rhaub cov ntug ntawm cov nyiam pob tshab groovent ua kom lub reagent tshem tawm ntawm ntug dej plam.
12. Hnov tag nrho cov phaus m1 / ntawm cov reagents sau nyob rau hauv lub beaker me me thiab khob, thiab sau cov ntaub ntawv.
13. Ua Rau:
Cov tshuaj pleev ua kua tau suav nrog cov qauv hauv qab no:
I- Cov tshuaj pleev li kua,%
M1-qhov loj ntawm lub beaker me me, hauv grams
M1'-qhov loj ntawm reagents sau nyob rau hauv lub beaker me me thiab beaker, hauv gram
M-qhov loj ntawm reagent poob mus rau cov qauv, hauv grams
14. Nias lub "fais fab hloov" mus rau "0" txoj hauj lwm rau lub zog tawm ntawm lub twj paj nruag.
15. Qhov kev sim ua tiav.
1. Tom qab qhov kev sim ua tiav, cov lus qhia kev nyab xeeb tu thiab nchuav cov haujlwm yuav tsum tau ua kom tiav! Tom qab ua tiav cov kauj ruam no, nws yog qhov zoo tshaj plaws los ua kev ntxuav tu nrog tu tus neeg sawv cev.
2. Ob leeg acid thiab alkali yog corrosive. Cov xeem cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes acid / alkali-pov thawj kom tsis txhob raug mob rau tus kheej.
3. Lub zog hluav taws xob ntawm lub ntsuas yuav tsum tau zoo!
