⑴ Potassium dichromate tov tshuaj: Raws li cov kev xav tau sib txawv, xaiv ib qho ntawm cov ntsiab lus hauv qab no. Daws cov poov tshuaj dichromate hauv dej ua ntej, tom qab ntawd maj mam ntxiv cov tshuaj sulfuric acid. Nco ntsoov tias cov cua sov yuav tuaj yeem tsim tawm rau lub sijhawm no, thiab lub thawv yuav tsum tiv thaiv kom tsis txhob tawg. Potassium dichromate tu kev daws teeb meem muaj lub zog tshem tawm muaj zog thiab muaj cov tshuaj tiv thaiv zoo. Zam kev sib cuag nrog cov tawv nqaij thiab khaub ncaws. Txhawm rau tiv thaiv kev puas tsuaj los ntawm nqus cov huab cua noo, qhov kua no yuav tsum muab ntim rau hauv lub thawv uas muaj lub hau. Yog tias qhov kev ntxuav tu tsis zoo, ntxiv me me ntawm cov potassium dichromate thiab cov tshuaj sulfuric acid, thiab txuas ntxiv siv nws. Txog thaum cov kua hloov xiav ntsuab-ntsuab, nws yuav tsis siv lawm. Thaum npaj cov tshuaj potassium dichromate tu kev daws teeb meem, nws raug nquahu kom siv high-temperature resistant ceramic tso tsheb hlau luam lossis cov kua qaub-tiv thaiv txha hniav laus lossis ntim yas. Thaum siv tsom iav, yuav tsum tau saib xyuas tshwj xeeb kom tiv thaiv nws los ntawm tawg vim tias kub dhau los, thiab zam kom tsis txhob siv lub tog raj ntsuas ntsuas los npaj nws.
RisTrisodium phosphate yog tsim ua kua dej 5% -10% aqueous, uas tuaj yeem siv los ntxuav cov roj av ntawm cov iav, tab sis cov iav corroded feem ntau yog siv los ua cov nplaim ntawm cov nplaim taws thiab ntxhib.
Txhua cov kua roj nitric acid tu ua rau hauv 50% aqueous tov, uas tuaj yeem siv los ntxuav lub raj microtiter. ⑷Ethylenediaminetetraacetic acid disodium (EDTA sodium ntsev) yog ua rau hauv 5% -10% aqueous tov, uas tuaj yeem ntxuav tawm cov nag lossis dawb adhering rau sab hauv phab ntsa ntawm cov khob iav. SolutionUrea kua Urea yog ib qho zoo rau cov ua kom tsis muaj protein ntau, thiab nws tsim nyog rau kev ntxhua khaub ncaws thiab sim cov raj nrog cov protein ntau xws li ntshav dej.
