Xa kuziwa ekulinganiseni nasekukhupheni umthamo othile walo naluphi na ulwelo, ii-pipettes ziyimfuneko kakhulu kwindawo yelabhoratri yanamhlanje. Ngokuxhomekeke kubukhulu bebhu kunye nomthamo omele uhanjiswe, iintlobo ezahlukeneyo zeepipettes zisetyenziswa ngokuqhelekileyo:
- Iipayipi zokufuduswa komoya
- Positive displacement pipettes
- Iipayipi zokulinganisa
- Iipayipi ezihlengahlengiswayo zoluhlu
Ngo-2020, siqala ukubona ii-micropipettes zokufuduswa komoya zidlala indima ebalulekileyo kumlo ochasene ne-COVID-19, kwaye zisetyenziselwa ukulungiselela iisampulu zokubhaqa i-pathogen (umzekelo, i-RT-PCR yexesha lokwenyani). Ngokuqhelekileyo, uyilo olubini olwahlukileyo lunokusetyenziswa, iipayipi ze-motor okanye ze-motorized air displacement.
IiPipettes zokufuduswa koMoya ngesandla kunye neePipettes zokufuduswa koMoya oneMoto
Kumzekelo wepayipi yokufuduka komoya, ipiston ishukunyiswa phezulu okanye ezantsi ngaphakathi kwepipette ukwenza uxinzelelo olubi okanye olulungileyo kwikholamu yomoya. Oku kuvumela umsebenzisi ukuba afake umoya okanye akhuphe isampuli yolwelo esebenzisa i-pipette elahlayo, ngelixa ikholomu yomoya kwi-tip ihlukanisa i-liquid kwiindawo ezingabonakaliyo ze-pipette.
Ukuhamba kwepiston kunokwenziwa ukuba kwenziwe ngesandla ngumqhubi okanye ngombane, oko kukuthi, umqhubi uhambisa ipiston ngokusebenzisa iqhosha lokutyhala elilawulwa yimoto.
Ukulinganiselwa kweepipettes zesandla
Ukusetyenziswa kwexesha elide leepayipi ze-manual kunokubangela ukuphazamiseka kunye nokulimala kumqhubi. Amandla afunekayo ukukhupha i-liquids kunye nokukhupha i-pipette tip, edibeneyo kunye nokunyakaza okuphindaphindiweyo okuphindaphindiweyo kwiiyure ezininzi, kunokunyusa amalunga, ngakumbi isithupha, i-elbow, i-wrist, kunye negxalaba, kwi-RS (I-repetitive muscle strain) ingozi.
Iipayipi zezandla zifuna ukuba iqhosha lebhontsi licinezelwe ukukhulula ulwelo, kanti iipayipi zombane zibonelela ngeergonomics ezingcono ngeqhosha elivuswe ngombane kulo mzekelo.
Iindlela ezizezinye zombane
Iipayipi ze-elektroniki okanye zemoto ziindlela ezizezinye ze-ergonomic kwiipayipi ze-manual eziphucula ngokufanelekileyo iziphumo zesampula kunye nokuqinisekisa ukuchaneka nokuchaneka. Ngokungafaniyo namaqhosha endabuko alawulwa ngubhontsi kunye nohlengahlengiso lwevolumu yencwadi, iipayipi zombane ziza kunye nojongano lwedijithali ukulungelelanisa umthamo kunye ne-aspirate kunye nokukhupha ngepiston yombane.
Ukukhethwa kweeMoto zeePipettes zombane
Ngenxa yokuba i-pipetting isoloko inyathelo lokuqala kwinkqubo yamanyathelo amaninzi, nakuphi na ukungachaneki okanye ukungafezeki okwenzekayo xa kulinganiswa le nxalenye encinci yolwelo kunokuvakala kuyo yonke inkqubo, ekugqibeleni kuchaphazela ukuchaneka ngokubanzi kunye nokuchaneka.
Yintoni ukuchaneka nokuchaneka?
Ukuchaneka kufezekiswa xa i-pipette ikhupha umthamo ofanayo ngamaxesha amaninzi. Ukuchaneka kufezekiswa xa i-pipette ikhupha umthamo ojoliswe kuyo ngokuchanekileyo ngaphandle kwempazamo. Ukuchaneka kunye nokuchaneka kunzima ukufezekisa ngexesha elifanayo, kodwa amashishini asebenzisa i-pipettes afuna ukuchaneka kunye nokuchaneka. Enyanisweni, ngulo mgangatho uphezulu kakhulu owenza ukuba kwenzeke ukuphinda kuveliswe iziphumo zovavanyo.
Intliziyo nayiphi na ipayipi ye-elektroniki yimoto yayo, echaphazela kakhulu ukuchaneka kunye nokuchaneka kwe-pipette, ngaphezu kwenani lezinye izinto ezibalulekileyo ezifana nobukhulu bephakheji, amandla kunye nobunzima. Iinjineli zoyilo zePipette ngokuyintloko zikhetha i-stepper linear actuators okanye iimoto zeDC. Nangona kunjalo zombini iinjini ze-stepper kunye neenjini ze-DC zinezibonelelo zazo kunye nokungalunganga.
DC Motors
Iinjini zeDC ziinjini ezilula ezijikelezayo xa kusetyenziswa amandla eDC. Abafuni udibaniso oluntsonkothileyo ukwenza injini ibaleke. Nangona kunjalo, ngokunikezelwa kweemfuno zentshukumo ehambelanayo yeepayipi ze-elektroniki, izisombululo zeemoto ze-DC zifuna isikrufu esongezelelweyo sokukhokela kunye nesixhobo sokuguqula isindululo esijikelezayo sibe sisindululo somgca kunye nokubonelela ngamandla afunekayo. Izisombululo ze-DC nazo zifuna indlela yempendulo ngendlela ye-sensor optical okanye i-encoder ukulawula ngokuchanekileyo indawo yepiston yomgca. Ngenxa ye-inertia ephezulu ye-rotor yayo, abanye abaqulunqi bangongeza kwakhona inkqubo ye-braking ukuphucula ukuchaneka kokumisa.
Iinjini zeStepper
Kwelinye icala, iinjineli ezininzi zikhetha izisombululo ze-stepper linear actuator ngenxa yokulula kwazo ukudibanisa, ukusebenza okugqwesileyo kunye neendleko eziphantsi. I-Stepper linear actuators zibandakanya iimotor zemagnethi ezisisigxina ezinerotor enentambo kunye nebha yefilament edityanisiweyo ukuvelisa intshukumo yomgca ngokuthe ngqo kwiipakethi ezincinci.
