Volumetric Flask

Volumetric flask Taw Qhia

Lub khob ntim hluav taws xob (ntsuas lub khob lossis cov nplaim hluav taws xob) yog ib qho ntawm cov iav tsom iav, uas yog ib qho kev sim tshuaj, ntsuas kom muaj qhov ntim npliag ntawm qhov kub tshwj xeeb. Volumetric flasks yog siv rau cov lus qhia meej thiab cov kev npaj ntawm cov qauv kev daws teeb meem.

Cov Lus Qhia

Ua ntej siv lub raj mis volumetric, yuav tsum muaj ob daim tshev hauv qab no.

1. Qhov ntim ntawm cov nplaim hluav taws xob hluav taws xob tau zoo ib yam nrog qhov xav tau.

2. Txheeb xyuas tias cork nruj thiab tsis xau.

Tso dej rau hauv lub raj mis ze rau ntawm txoj kab cim, ntsaws cov kab kom nres kom khov, thiab cia nws sawv ntsug li 2 feeb. Txheeb xyuas nrog daim ntawv lim dej raws cov leeg ntawm lub raj mis kom pom tias tsis muaj dej ntws tawm. Yog tias nws tsis xau, tig lub ntsaws 180 °, ntsaws kom nruj, sib zog rau hauv, thiab ntsuas kev ntsuas txau hauv qhov kev taw qhia. Cov txwv nres yuav tsum muab khaws cia rau qhov chaw zoo. Nws raug nquahu kom muab txoj hlua khi rau lub caj dab caj dab kom nws tsis txhob poob lossis sib xyaw nrog lwm tus nres.
