Xa kufikwa ekulinganiseni nasekukhupheni umthamo othile walo naluphi na ulwelo, ii-pipettes zibaluleke kakhulu kwimeko yelabhoratri yanamhlanje. Ngokuxhomekeke kubukhulu belebhu kunye nomthamo ekufuneka ukhutshwe, iintlobo ezahlukeneyo zee-pipettes zihlala zisetyenziswa:
- Iipayipi zokuhambisa umoya
- Iipayipi zokufuduka ezilungileyo
- Iipipette zokulinganisa
- Iipipette zoluhlu oluhlengahlengiswayo
Ngowama-2020, siqala ukubona ii-micropipettes zokufuduka komoya zidlala indima ebalulekileyo kwidabi lokulwa ne-COVID-19, kwaye zisetyenziselwa ukulungiselela isampuli yokufunyaniswa kwezifo (umz., i-RT-PCR yexesha langempela). Ngokwesiqhelo, uyilo ezimbini ezahlukeneyo lungasetyenziswa, ii-pipettes zokufuduka komoya ezenziwe ngesandla okanye eziqhutywa ngenjini.
IiPipettes Zokuhambisa Umoya Ngesandla vs IiPipettes Zokuhambisa Umoya Eziqhutywa Ngenjini
Kumzekelo wepayipi yokuhambisa umoya, i-piston inyuswa okanye isiwe ngaphakathi kwipayipi ukuze idale uxinzelelo olubi okanye oluhle kwikholamu yomoya. Oku kuvumela umsebenzisi ukuba aphefumle okanye akhuphe isampuli yolwelo esebenzisa incam yepayipi elahlwayo, ngelixa ikholam yomoya ekwincam yahlula ulwelo kwiindawo ezingalahlwayo zepayipi.
Ukuhamba kwepiston kungayilwa ukuba kwenziwe ngesandla ngumqhubi okanye nge-elektroniki, oko kukuthi umqhubi uhambisa ipiston ngokusebenzisa injini elawulwa liqhosha lokutyhala.
Imida yeepayipi ezisetyenziswa ngesandla
Ukusetyenziswa ixesha elide kwee-pipettes ngesandla kunokubangela ukungakhululeki kwanokwenzakalisa umntu osebenzisa loo matshini. Amandla afunekayo okukhupha ulwelo kunye nokukhupha incam ye-pipette, kunye neentshukumo eziphindaphindwayo rhoqo kangangeeyure ezininzi, anokunyusa amalungu, ingakumbi ubhontsi, ingqiniba, isihlathi, kunye negxalaba, kumngcipheko we-RS (I repetitive muscle strain).
Iipipettes ezenziwe ngesandla zifuna ukuba iqhosha lesithupha licinezelwe ukuze kukhululwe ulwelo, ngelixa iipipettes ze-elektroniki zibonelela nge-ergonomics engcono ngeqhosha elisebenza nge-elektroniki kulo mzekelo.
Iindlela zobuchwephesha
Iipipetti ze-elektroniki okanye ezisebenzisa injini zezona ndlela zingcono kuneepipetti ezenziwe ngesandla eziphucula ngempumelelo imveliso yesampulu kwaye ziqinisekise ukuchaneka nokuchaneka. Ngokungafaniyo namaqhosha emveli alawulwa ngobhontsi kunye nokulungiswa kwevolumu ngesandla, iipipetti zombane ziza nojongano lwedijithali ukulungisa ivolumu kunye nokuphefumla kunye nokukhupha ngepiston esebenza ngombane.
Ukukhethwa KweeMoto ZeePipetti Ze-elektroniki
Ngenxa yokuba ukubhobhoza ngemibhobho kudla ngokuba linyathelo lokuqala kwinkqubo enamanyathelo amaninzi, naziphi na iimpazamo okanye ukungachaneki okwenzekayo xa kulinganiswa le nxalenye incinci yolwelo kunokuvakala kuyo yonke inkqubo, ekugqibeleni kuchaphazela ukuchaneka kunye nokuchaneka ngokubanzi.
Yintoni ukuchaneka nokuchaneka?
Ukuchaneka kufumaneka xa i-pipette ikhupha ivolumu efanayo amaxesha amaninzi. Ukuchaneka kufumaneka xa i-pipette ikhupha ivolumu ekujoliswe kuyo ngokuchanekileyo ngaphandle kwempazamo. Ukuchaneka nokuchaneka kunzima ukukufezekisa ngaxeshanye, kodwa amashishini asebenzisa ii-pipette afuna ukuchaneka nokuchaneka. Enyanisweni, ngulo mgangatho uphezulu kakhulu owenza kube nokwenzeka ukuvelisa iziphumo zovavanyo.
Intliziyo yayo nayiphi na i-elektroniki pipette yimoto yayo, nto leyo echaphazela kakhulu ukuchaneka nokuchaneka kwe-pipette, ukongeza kwezinye izinto ezibalulekileyo ezifana nobungakanani bephakheji, amandla kunye nobunzima. Iinjineli zoyilo lwe-pipette zikhetha ikakhulu ii-stepper linear actuators okanye ii-DC motors. Nangona kunjalo, zombini ii-stepper motors kunye nee-DC motors zinezibonelelo kunye neengxaki zazo.
Iimoto zeDC
Iimoto zeDC ziimoto ezilula ezijikelezayo xa kusetyenziswa amandla eDC. Azidingi uqhagamshelo oluntsonkothileyo ukuze imoto isebenze. Nangona kunjalo, ngenxa yeemfuno zokuhamba ngomgca zeepipettes ze-elektroniki, izisombululo zeemoto zeDC zifuna isikrufu esongezelelweyo se-lead kunye negiya ukuguqula ukuhamba okujikelezayo kube kukuhamba ngomgca kwaye zinike amandla afunekayo. Izisombululo zeDC zikwafuna indlela yokuphendula ngendlela ye-optical sensor okanye i-encoder ukulawula ngokuchanekileyo indawo yepiston emgca. Ngenxa yokungabi namandla okuphezulu kwe-rotor yayo, abanye abayili banokongeza inkqubo yokuqhobosha ukuphucula ukuchaneka kokubeka.
Iimoto ze-stepper
Kwelinye icala, iinjineli ezininzi zikhetha izisombululo ze-stepper linear actuator ngenxa yokuba zilula ukuhlanganiswa, ukusebenza kakuhle kunye nexabiso eliphantsi. Ii-stepper linear actuators ziquka ii-motor ze-magnet stepper ezisisigxina ezine-rotor enemisonto kunye ne-filament bar edibeneyo ukuvelisa intshukumo ethe ngqo kwiipakethe ezincinci.
