Girazi test tubes

Inoratidzira mabhodhi akatenderedzwa uye tambo yakadzika yekupedzisa yekuwedzera kwekuchengetedza mabasa iwayo akakosha mabasa, aya anorema anorodzwa akazara simba renyama.
Iyo yakatenderedzwa pasi inobvumira kuendesa zvakanaka kwekupisa uye nyore kuchenesa. 

Iyi tsika yegirazi inocheka aya magirazi egirazi tubes inoratidza kusimba kwekuvakwa kwekusagadzikana kwekushandiswa kwekushandiswa kwekushandisa. Iyo screw cap inopa chisimbiso chemagetsi kudzivirira sampula uye kubuda kwemvura. Iyo yakajeka girazi zvinyorwa zvinobvumira zviri nyore kutarisisa kwekuongorora kwemuenzaniso. Iwo machubhu anoenderana nemaitiro akajairika ekurambidza senge centrifugation, incubation uye sampula yekuchengetedza. Ivo vanogona zvakare kusanganisira mamaki ekupedza kudzidza kuti vhoriyamu zviyero uye kuzivikanwa kwechirevo.
