30mm 32mm Roj Hmab Bung Chemistry

Muaj ntau yam elastomer formulations rau stoppers. Cov roj hmab ntuj yog lub hom phiaj dav dav elastomer, feem ntau yog siv rau cov dej ua kua filling cov khoom hauv pH ntau ntawm 4.0-7.5. Nws resealability yog qhov zoo dua hauv kev siv ntau koob. Cov mis siv cov roj hmab qhuav thiab tsis muaj kua latex. Lub voj voog tom qab kev kho mob (PEP 1) txo cov ntsiab lus ntawm cov khoom tsis hloov pauv hauv cov khoom siv roj hmab. Cov mis extractable ntawm butyl stopper yog tsawg heev thiab yuav siv tau nrog kua, lyophilized los yog qhuav hmoov cov khoom uas yuav tsum tau tiv thaiv cov pa oxygen los yog ya raws. Lub stopper coated nrog PTFE muab ib qho inert barrier kom txo qhov kev sib cuam tshuam ntawm cov reagent thiab lub thawv.

Cov roj hmab stopper tiv thaiv cov tshuaj los ntawm ib puag ncig cuam tshuam thiab pab tswj cov tshuaj zoo thiab kev nyab xeeb
