Kuaj cov khoom siv feem ntau muab faib ua ob pawg:
Ib qho: Cov khoom siv ruaj khov
Piv txwv li: conical flasks thiab ntsuas cov thooj voos kheej kheej, uas feem ntau muaj lub neej pabcuam ntev thiab tuaj yeem siv tau ntev yog tias zoo khaws cia;
Ob: Cov Neeg Siv Khoom Siv Tau Los
Piv txwv li, cov lus qhia pipette, pipette cov lus qhia, hnab looj tes roj hmab rau kev sim, thiab lwm yam, yog siv ntau zaus hauv chaw soj nstuam thiab tau noj sai sai.
Qhov tseeb, ob hom kev siv tau yooj yim los tswj hwm. Rau cov neeg ruaj khov, feem ntau lawv yuav tsum muab tso rau ntawm kev sim khib tom qab raug ntxuav thiab qhuav.
Txog kev yooj yim ntawm kev sim siv, lawv tuaj yeem muab tso rau hauv pawg. Piv txwv li, ntsuas cov thooj voos kheej kheej tau muab tso rau ntawm tib lub khib, thiab beakers tau muab tso rau ntawm lwm cov khib. Ib qho ntxiv, txhua hom khoom siv tau txheeb raws li qhov kev txiav txim raws li lub peev xwm. Rau cov neeg siv tau yooj yim uas tsis yooj yim sawv ntsug sawv ntsug, xws li kev sim tub thiab centrifuge tub, lawv tuaj yeem muab tso rau hauv lwm cov tub rau khoom huv thiab qhuav.
