Lapho kuziwa ekuzuzeni ucwaningo, ukunemba kuyinto ebaluleke kakhulu. Lokhu kusho ukuthi abacwaningi bayakwazi ukwenza ukunyakaza okuqondile noma ukudlulisa amanzi amancane besebenzisa ipayipi, okuzochazwa kabanzi kulesi sihloko. Uma sibheka ngokucophelela, kunezinhlobo ezihlukahlukene zamapayipi asetshenziselwa izinjongo ezihlukahlukene ezimweni zaselebhu. Ngakho-ke, kudingeka kukhethwe ipayipi elifanele ngokuphathelene nomsebenzi. Ezihlokweni, kunamapharamitha okufanele alandelwe ngokuphathelene nokusetshenziswa kahle kwe-pipette, kuhlanganise kodwa kungagcini lapho, ukufaniswa, ukunakekelwa nekhwalithi yama-pipette, ngoba lezi zici zithonya ngokuqondile imiphumela yanoma yiluphi ucwaningo olunikeziwe. Izimpikiswano ezivezwe lapha zikhuluma ngokusetshenziswa kwe-pipette ekuvuseleleni ucwaningo olunjalo lwezokwelapha nokusebenza kwayo ekuphenduleni imibuzo ebalulekile yezokwelapha. Njengoba eminye imikhakha ithuthuka, kanjalo nokuthuthuka kwe-pipetting ngoba kunezindlela ezintsha zokuthuthuka kwe-pipetting ezishintsha ubuso bocwaningo njengokuzenzakalela kanye nokwenza izinhlelo ze-pipetting zibe ngamanani. Amaqembu ocwaningo angasebenzisa lokhu kuthuthukiswa ukuze akwazi ukuthuthukisa ukuqonda kwawo izinqubo futhi ngaleyo ndlela athuthukise ukwethembeka komsebenzi wawo. Ekuphetheni, ukuthuthukiswa kwesayensi kuyasiza isayensi ngokuqinisekisa ukuthi abacwaningi bezokwelapha bayoba nama-pipette njalo emathulini abo kodwa okubaluleke nakakhulu, kugcizelela indlela yokusebenzisa kahle i-pipette ukuze bathole imiphumela elungile elindelwe. Ikhwalithi kanye nemikhuba emihle ephathelene nokusetshenziswa kwama-pipette kuzosiza ukugcina ukubaluleka kocwaningo lwezokwelapha futhi kusize ekuthuthukiseni kwalo.
