Cov hnab looj tes nqus tsev vacuum yog qhov nkag siab zoo rau cov pa oxygen thiab dej hauv kev kho ua ntej ntawm cov tshuaj tiv thaiv thiab cov qauv kuaj, thiab tsis tuaj yeem ua tau nyob rau hauv ib puag ncig. Txawm hais tias cov tshuaj tiv thaiv ntawm cov tshuaj no tuaj yeem ua rau hauv lub tshuab nqus tsev, nws tsis tuaj yeem ua haujlwm, uas ua rau nws nyuaj heev rau kev kho thawj zaug ntawm cov tshuaj tiv thaiv cov tshuaj tiv thaiv ntawm cov tshuaj no. Kev siv lub tshuab nqus tsev vacuum lub thawv tuaj yeem ua rau cov khoom siv no ua haujlwm, hnov mob thiab kuaj dawb nyob rau hauv cov ntaub ntawv ntawm anaerobic thiab dej-dawb, yog li nws nyob rau hauv chemistry, tshuaj, lom, raw) Kev npaj thiab kev tshawb fawb tau dav siv.
