DMSO Dimethyl Sulfoxide (CAS 67-68-5) - Kev nyab xeeb
Cov ntaub ntawv kev nyab xeeb:
1. Tsis txhob siv daim tawv nqaij thiab qhov muag tsis pom kev thiab ua raws li cov lus pom zoo ntawm kev tuav thiab cov cuab yeej tiv thaiv tus kheej hauv SDS. DMSO tuaj yeem nqus tau los ntawm daim tawv nqaij thiab tuaj yeem ua rau muaj kev nkag mus ntawm lwm yam tshuaj.
2. DMSO yog cov kua hluav taws xob hluav taws xob nrog lub teeb nyem siab heev. Khaws nws kom deb ntawm qhov hluav taws kub thiab kub heev, thiab ua raws li SDS siv tau.
3. Ua tib zoo saib xyuas kom tsis txhob muaj kev sib tsoo lossis sib chwv qhov muag.
4. Kev sib cuag ntev lossis rov ua dua tuaj yeem ua rau tawv nqaij khaus lossis lwm yam teebmeem. Zam kom tsis txhob raug cuam tshuam thiab ua raws li SDS cov lus pom zoo.
