Cov qauv tsim tshwj xeeb ua rau cov khoom no piv rau cov khoom zoo sib xws nrog qis qis qis, kev saib xyuas qis dua, qis dua reagent noj thiab tus nqi siab dua.
Cov khoom siv txhaj tshuaj: lub tshuab nqus tsev nqus peristaltic twj tso kua mis, thiab lub twj tso kua mis ntawm lub reagent yeej ib txwm muaj huab cua tsis zoo, kom tsis txhob xeb ntawm cov tubing, thaum ua cov reagent sib tov ntau dua thiab hloov tau.
Sealed Digestion Cheebtsam: high -temperature high-pressure digestion system, accelerating the reaction process, overcome the volatile corrosive gas exposure system equipment corrosion.
Reagent tube: imported pob tshab hloov PTFE hose, txoj kab uas hla ntau dua 1.5mm, txo cov caij nyoog ntawm cov dej zoo li cov khoom txhaws.
Ib txoj kev raws li | Lub teb chaws tus qauv GB11914-89 << Dej Zoo - Kev txiav txim siab ntawm cov tshuaj oxygen xav tau - dichromate potassium >> | |
