Izimpipethi ziyindlela ezikhoyo kwi-labazakhomphilo esendaweni sasekhaya. Bazokubiza ngokukhulu kumakhono amadala emasayensi. Izimpipethi zihlelwa ukuthi ziphindele amaliqulezi nokuthuthukisa okulandelayo lokuhlola, okuningi lapho ukuhlola olungaphakathi kwezitshisi. Lapha ngesikhatsi sesikusha, sizibophelela izinhlobo ezifanayo zezimpipethi, izinyathelo zakhe, kunye nophawulekisweni lokusebenzela izintlelo ezincane zezimpipethi ukuze uziphindvise amalungu.
Ukuyenza ngenqanawe yomoya. Lolu hlobo lwe pipette lusho elokuqala olufunekayo lokulanda. Lolu hlobo luhlu luninzi olubekwa kwiilabizini ngokuthi kungavumelekanga nokuba ngendlela esikhathini. Indlela yokusebenza komoya-omoya, uyahamba ukwakhiwa isibindi esiphezulu, okulula amalayithi angaphandle. Lokhu lingacabanga ukuxhasa umsebenzi wokusetyenziswa inkomba enye yamalayithi ngokuphakeme nokuphakanyiselo. Amapipelete ame apha amazinye ezifane neziphi zimangele, futhi abasebenzisi babenemisebenzi omnyama obungaphezulu, phakathi kwalokho nokusetshenziswa kwezinhlobo eziningi zomsebenzi, ngokushesha kodwa akukho ngezinto eziqhutywayo, ngokusetshenziswa izinhlobo, iinkombizi zeenzime, kunye neenteka zakuseta PCR. Amapipelete ame asetshenziswa ngeminyaka emingi ekugcineni lokhu kungaba kule labizini.
U-pipetshi lwe-positive-displacement ulenjini elingapheleleyo kwiindawo eziningi. Ukhuphazima kulula ukuthi ngokubanzi kakhulu phakathi kwesiqephu sase-air-displacement ngoba usebenzisa isitonsi esifumanekayo ngokuphi ndawonye ngesicwangciso. Oku kungafanele yokusebenza nge-amathumela okukhulu nokulandelayo. Ngokwesikhatsi, ukuhlaba kwezindlela zokugcinwa zizihlinzekiswa kunye nezinhlobo zokukhotholwa ezinethile. Lokhu kuhluke kakhulu kwiindawo ze-biochemistry kunye ne-molecular biology. Ukufunda ukuthi nini ubenza nge-pipetshi le-positive-displacement ucabanga amaphutha angamagunyazwe apho hlanganiswa ngezilimi.
Ngokubanzi, okusetyenziswa kwezimpahla ezihlukomele zezibhedlela kumangoshe izinto ezinikezela amaxesha lokuhlola amalendulo. Ukubonisa ngezimpahla ezintathu, zimpahla ezihlukomele ziziprogamaywa, okungakho ngokushesha ukuthi uzikhangeleke kakhulu nokuziphatha. Zingabonisa kakhulu labasebenzi laba labhizinca, apho ispeedi nesibhedlela sikhona kuhlanganiswa. Ngakwesinye, iimpahla yezihlukomele eziningi zizoba zikuphumelela ngokulandelayo ukuhlukomeleka kwezindlela ezininzi. Lomkhakha lokusebenza ayifuna ukuthi asave umla wakhe ngaphandle kokuthi akufanele ukubheka nokuba ubone ukuthi ungene kudluliselo lokuqaphepha ukusetyenziswa kwemfana wesibhedlela.
Amalidelo amahlula kakhulu abesetyenziswa ngokubekwa kwezilabulali. Ngaphandle kokuba ipipethi yikhona ngenqanawe, ukhona ukusetshenziswa kwaye akukho lokhu olungakho lokuqinisekileyo, uzoba uyingxenye olunguqukethwe. Ukuxhasa kweSithembiso saseZazibona singezwa ngokupheleleyo ukulinganisa izindlela zokuseta, ukufakwa kwezindawo ezidingekayo, kunye nokuhlukanisana / izindlela ezidingekayo nezidingekayo ngasemva kunye nokusetshenziswa. Izindlela eziqhutywa zingahlinzekela ukuba isikampani esisetyenzisiwe siyehlukeneyo, okuningi lokuhlinzekela lokusebenza labo iimboniso. Ngakwesokudla, ziqinisekisana nokugcina izipipethi zikhona ngomoya wendawo ukuba umsebenzi wenqanawe kunye nokutholakalo kuyatholakele.
Ngokwesibonelo, iziphiphethi zikhupha isiphumo esincane njengamavuri asehlulekileyo ezasezinhlabathalo zokuthutha lokusebenza ukuba kuhle kunye nekuvumelanisa kwiimboniso zesayensi. Ngokukhona kwesibhedlela, kungakhothandeka ukubona izintshangiso ezintsha ezizoba kukhishwa noma kulula amabili okanye amahhalelo wekhazi kunye nokugcina ngaphandle kwezilabulali ezilabathalo. Yizintshangiso eziqondisiwe yiizinto ezizama ukwenza ukuthi amakhosi wakhe wakhiwo akhethwe kanye nokuba bakwazi ukufika emaxwebheni akhona kwindawo yokuthutha.
Kunegcino langakho lomlandu ukuze kuzibonise ukuthi kusenzeniwe ukudibanisa kanye nokuhlola kweendaba edigitali ngaphandle kwezilabathalo. Ukusebenza okukhulu kunye nokuhlola kuhlanganiswe ngenkinga leyiindlela lokusebenza yezimpawu ezimbili ezinomsindo kunye nokuhlola komlambo wendawo. Ukusebenzela lezi zinto ezintsha zakhiya ukuba zingasiza izilabathalo zokuthutha ukusebenzela ngokulandelana nokuhlola ukusuka kwezindawo ezichangeke kwezinhlabathalo.
