Amathiphu, njengezinto ezisetshenziswayo ezisetshenziswa ngama-pipettes, ngokuvamile zingahlukaniswa zibe amathiphu ajwayelekile; amathiphu ahlungiwe;amathiphu e-pipette yesihlungi esisebenzayo, njll.
1. Ithiphu evamile iyithiphu esetshenziswa kabanzi. Cishe yonke imisebenzi yamapayipi ingasebenzisa amathiphu ajwayelekile, okuwuhlobo lwamathiphu olungabizi kakhulu.
2. Ithiphu ehlungiwe iyinto esebenzisekayo edizayinelwe ukugwema ukungcoliswa futhi ivamise ukusetshenziswa ekuhloleni okufana ne-molecular biology, cytology, kanye ne-virology.
3. Ingaphezulu lethiphu ye-low-adsorption yenze ukwelashwa kwe-hydrophobic, okunganciphisa uketshezi olucindezelayo oluphezulu olushiya izinsalela eziningi kuphoyinti.
PS: Ithiphu yomlomo obanzi ilungele ukumunca izinto ezibonakalayo, i-genomic DNA, kanye noketshezi lwamaseli.
Ungakhetha kanjani ithiphu elihle le-pipette?
Isitatimende singashiwo siyiqiniso ngokwengxenye kodwa singelona iqiniso ngokuphelele. Iphuzu elingafakwa ku-pipette lingakwazi ngempela ukwakha uhlelo lwe-pipetting nge-pipette ukuze liqaphele umsebenzi wepayipi, kodwa ingabe lokhu kunokwethenjelwa? Kudingeka uphawu lombuzo lapha.
Izici zethiphu yephuzu le-pipette
Ngakho-ke yimaphi amaphuzu amancane okufanele ithiphu elihle libe nawo?
Ithiphu enhle incike ekugxileni, ekucindezelweni, futhi iphuzu elibaluleke kakhulu i-adsorption;
1. Ake sikhulume nge-taper kuqala: uma kungcono, ukufana ne-pipette kuhle kakhulu.
2. I-Concentricity: I-Concentricity iwukuthi umbuthano phakathi kwesihloko sethiphu kanye nesixhumanisi phakathi kwethiphu ne-pipette yisikhungo esifanayo. Uma kungesona isikhungo esifanayo, kusho ukuthi ukugxila akukuhle;
3. Okokugcina, okubaluleke kakhulu ukumuncwa kwethu: ukumuncwa kuhlobene nempahla yethiphu. Uma impahla yethiphu ingalungile, izothinta ukunemba kwepayipi futhi ibangele inani elikhulu loketshezi oluzogcinwa noma okubhekiselwa kulo njengokulenga odongeni, okubangela amaphutha ku-pipetting.
Ngakho-ke wonke umuntu kufanele anake ngokukhethekile amaphuzu amathathu angenhla lapho ekhetha ithiphu ye-pipette. Umugqa wamathiphu amabi uhlukaniswe ngokucacile ngokuhlukile! Uzobona ukuhlanekezela okusobala, kodwa lesi isinyathelo esibaluleke kakhulu ekukhetheni ithiphu elihle. Futhi, sicela uqaphele ukufakwa kwamathiphu ku-pipette yesiteshi esisodwa kanye ne-pipette yamashaneli amaningi ihlukile. Ngeshaneli eyodwa, faka ithiphu liqonde phezulu ethiphu le-pipette, cindezela kancane, bese ulijika kancane ukuze uliqinise. Kumashaneli amaningi, iziteshi eziningi ze-pipette kufanele zihambisane namathiphu amaningi, afakwe nge-angle, futhi anyakaze kancane emuva naphambili ukuze aqinise; Musa ukushaya ngokuphindaphindiwe i-pipette ukuze uqinisekise ukungangeni komoya kwephuzu.
Ukuphendula lo mbuzo kudinga idatha ukuze ukhulume
1. Qondanisa i-pipette nethiphu yokuhlola ukusebenza.
2. Bala ukunemba kokusebenza kwepayipi ngemuva kokuyiguqula ibe yivolumu ngokuya ngobuningi boketshezi lokuhlola.
3. Okumele sikukhethe ukuthi sibe nethiphu elihle. Uma i-pipette ne-tip zingahambisani kahle, kusho ukuthi ukuqina kwephuzu kanye ne-pipette akukwazi ukuqinisekiswa, okwenza imiphumela yomsebenzi ngamunye ingenzeki ukukhiqiza.
