Uma kukhulunywa ngokulinganisa nokukhipha umthamo othile wanoma yiluphi uketshezi, ama-pipette abalulekile kakhulu endaweni yanamuhla yelabhorethri. Kuye ngobukhulu belebhu kanye nomthamo okudingeka ukhishwe, izinhlobo ezahlukene zama-pipette zivame ukusetshenziswa:
- Amapayipi okufuduka komoya
- Amapayipi amahle okufuduka
- Amapayipi okulinganisa
- Amapayipi obubanzi obulungisekayo
Ngo-2020, sesiqala ukubona ama-micropipettes okufuduka komoya edlala indima ebalulekile empini yokulwa ne-COVID-19, futhi asetshenziselwa ukulungiselela amasampula okutholakala kwezifo (isb., i-RT-PCR yesikhathi sangempela). Ngokuvamile, kungasetshenziswa imiklamo emibili ehlukene, ama-pipettes okufuduka komoya asebenzisa isandla noma asebenzisa injini.
Ama-Pipette Okuhambisa Umoya Ngesandla vs Ama-Pipette Okuhambisa Umoya Ngenjini
Esibonelweni sepayipi lokuhambisa umoya, i-piston ihanjiswa phezulu noma phansi ngaphakathi kwepayipi ukuze kudalwe ingcindezi engemihle noma enhle kukholamu yomoya. Lokhu kuvumela umsebenzisi ukuthi aphefumule noma akhiphe isampula yoketshezi esebenzisa ithiphu lepayipi elilahlwayo, kuyilapho ikholomu yomoya esesicongweni ihlukanisa uketshezi ezingxenyeni ezingalahlwa zepayipi.
Ukunyakaza kwepiston kungaklanywa ukuthi kwenziwe ngesandla ngumqhubi noma ngogesi, okungukuthi umqhubi uhambisa ipiston ngokusebenzisa injini elawulwa yinkinobho yokucindezela.
Ukulinganiselwa kwamapayipi esandla
Ukusetshenziswa isikhathi eside kwama-pipettes ngesandla kungabangela ukungakhululeki ngisho nokulimala kumuntu osebenzisa i-pipette. Amandla adingekayo ukuze kukhishwe uketshezi futhi kukhishwe i-pipette tip, kuhlanganiswe nokunyakaza okuphindaphindiwe amahora amaningana, kungandisa amalunga, ikakhulukazi isithupha, indololwane, isihlakala, kanye nehlombe, ngengozi ye-RS (I repetitive muscle strain).
Ama-pipette enziwe ngesandla adinga inkinobho yesithupha ukuthi icindezelwe ukuze kukhishwe uketshezi, kanti ama-pipette e-elekthronikhi anikeza i-ergonomics engcono ngenkinobho eqaliswa ngogesi kulesi sibonelo.
Ezinye Izindlela Ze-elekthronikhi
Ama-pipette kagesi noma anenjini ayizindlela ezingcono kakhulu kune-pipette enziwa ngesandla ezithuthukisa ngempumelelo umkhiqizo wesampula futhi ziqinisekise ukunemba nokunemba. Ngokungafani nezinkinobho zendabuko ezilawulwa yisithupha kanye nokulungiswa kwevolumu ngesandla, ama-pipette kagesi eza nesixhumi esibonakalayo sedijithali ukulungisa ivolumu kanye nokufutha nokukhipha nge-piston esebenza ngogesi.
Ukukhethwa Kwemoto Yama-Pipettes E-elekthronikhi
Ngenxa yokuthi ukufaka amapayipi kuvame ukuba yisinyathelo sokuqala enkambisweni enezinyathelo eziningi, noma yikuphi ukungalungi noma ukungapheleli okwenzeka lapho kulinganiswa le ngxenye encane yoketshezi kungazwakala kuyo yonke inqubo, ekugcineni kuthinte ukunemba kanye nokunemba okuphelele.
Kuyini ukunemba nokunemba?
Ukunemba kutholakala lapho i-pipette ikhipha ivolumu efanayo izikhathi eziningi. Ukunemba kutholakala lapho i-pipette ikhipha ivolumu eqondiwe ngokunembile ngaphandle kwephutha. Ukunemba nokunemba kunzima ukukufeza ngesikhathi esisodwa, kodwa izimboni ezisebenzisa ama-pipette zidinga kokubili ukunemba nokunemba. Eqinisweni, yileli zinga eliphakeme kakhulu elenza kube nokwenzeka ukukhiqiza imiphumela yokuhlola.
Inhliziyo yanoma iyiphi i-pipette kagesi yinjini yayo, okuthinta kakhulu ukunemba nokunemba kwe-pipette, ngaphezu kwezinye izinto ezibalulekile njengosayizi wephakheji, amandla kanye nesisindo. Onjiniyela bokuklama i-pipette bakhetha kakhulu ama-actuator e-stepper linear noma ama-motor e-DC. Kodwa-ke, womabili ama-motor e-stepper kanye nama-motor e-DC anezinzuzo nezinkinga zawo.
Ama-DC Motors
Ama-motor e-DC ayizinjini ezilula ezijikelezayo lapho kusetshenziswa amandla e-DC. Azidingi ukuxhumeka okuyinkimbinkimbi ukuze imoto isebenze. Kodwa-ke, uma kucatshangelwa izidingo zokunyakaza okuqondile zama-pipettes kagesi, izixazululo zezimoto ze-DC zidinga isikulufu esengeziwe se-lead kanye negiya ukuze kuguqulwe ukunyakaza okujikelezayo kube ukunyakaza okuqondile futhi kunikeze amandla adingekayo. Izixazululo ze-DC nazo zidinga indlela yokuphendula ngesimo senzwa yokukhanya noma i-encoder ukulawula ngokunembile indawo ye-piston eqondile. Ngenxa yokungabi namandla okuphezulu kwe-rotor yayo, abanye abaklami bangase bangeze nesistimu yokubhuleka ukuze kuthuthukiswe ukunemba kokubeka.
Ama-stepper motors
Ngakolunye uhlangothi, onjiniyela abaningi bakhetha izixazululo ze-stepper linear actuator ngenxa yokuthi zilula ukuhlanganiswa, ukusebenza kahle kakhulu kanye nezindleko eziphansi. Ama-stepper linear actuator aqukethe ama-motor e-magnet stepper ahlala njalo ane-rotor enezintambo kanye ne-filament bar ehlanganisiwe ukukhiqiza ukunyakaza okuqondile okuqondile emaphaketheni amancane.
