Pankhani ya kuyeza ndi kugawa kuchuluka kwamadzi aliwonse, ma pipette ndi ofunikira kwambiri masiku ano a labotale. Kutengera kukula kwa labu ndi kuchuluka kwake komwe kumayenera kuperekedwa, mitundu yosiyanasiyana ya ma pipette imagwiritsidwa ntchito:
- Ma pipette oyendetsa mpweya
- Ma pipette abwino osamutsidwa
- Miyezo ya pipette
- Ma pipette osinthika osiyanasiyana
Mu 2020, tikuyamba kuwona ma micropipettes osuntha mpweya akugwira ntchito yofunika kwambiri pankhondo yolimbana ndi COVID-19, ndipo amagwiritsidwa ntchito pokonzekera zitsanzo zozindikiritsa tizilombo toyambitsa matenda (mwachitsanzo, RT-PCR). Childs, mapangidwe awiri osiyana angagwiritsidwe ntchito, pamanja kapena galimoto mpweya kusamutsidwa pipettes.
Manual Air Displacement Pipettes vs Pipettes Yoyendetsa Magalimoto Oyendetsa Magalimoto
Mu chitsanzo cha pipette yosamutsidwa ndi mpweya, pisitoni imasunthidwa mmwamba kapena pansi mkati mwa pipette kuti ipangitse kupanikizika koipa kapena koyenera pamtunda wa mpweya. Izi zimathandiza wosuta pokoka mpweya kapena eject chitsanzo madzi ntchito disposable pipette nsonga, pamene ndime ya mpweya mu nsonga amalekanitsa madzi ku mbali sanali disposable wa pipette.
Kusuntha kwa pistoni kumatha kupangidwa kuti kuchitidwe pamanja ndi woyendetsa kapena pakompyuta, mwachitsanzo, woyendetsa pisitoniyo pogwiritsa ntchito makina owongolera batani.
Zochepera pamanja pipettes
Kugwiritsa ntchito kwa nthawi yayitali ma pipettes kungayambitse kupweteka komanso kuvulaza kwa woyendetsa. Mphamvu yofunikira kugawira zamadzimadzi ndikutulutsa nsonga ya pipette, kuphatikiza kusuntha kobwerezabwereza pafupipafupi kwa maola angapo, imatha kuwonjezera zolumikizira, makamaka chala chachikulu, chigongono, dzanja, ndi phewa, pachiwopsezo cha RS (I mobwerezabwereza kupsinjika kwa minofu).
Ma pipette a pamanja amafuna kuti batani la chala chachikulu kuti likanikizidwe kuti litulutse madziwo, pamene ma pipette amagetsi amapereka ma ergonomics abwinoko ndi batani lamagetsi mu chitsanzo ichi.
Njira Zina Zamagetsi
Ma pipette amagetsi kapena oyendetsa galimoto ndi njira zina za ergonomic za pipette zamanja zomwe zimasintha bwino zitsanzo ndikuwonetsetsa kulondola komanso kulondola. Mosiyana ndi mabatani omwe amayendetsedwa ndi chala chachikale komanso kusintha kwa voliyumu yamanja, ma pipette amagetsi amabwera ndi mawonekedwe a digito kuti asinthe voliyumu ndi kukhumba ndi kutulutsa kudzera pa pistoni yoyendetsedwa ndi magetsi.
Kusankhidwa Kwa Magalimoto Kwa Ma Pipettes Amagetsi
Chifukwa chakuti pipetting nthawi zambiri imakhala sitepe yoyamba muzochitika zambiri, zolakwika zilizonse kapena zolakwika zomwe zimachitika poyeza kachigawo kakang'ono kamadzimadzi kameneka kakhoza kumveka panthawi yonseyi, ndipo pamapeto pake zimakhudza kulondola ndi kulondola.
Kodi kulondola ndi chiyani?
Kulondola kumatheka pamene pipette imatulutsa voliyumu yomweyi kangapo. Kulondola kumatheka pamene pipette ikupereka voliyumu yowunikira molondola popanda cholakwika chilichonse. Kulondola ndi kulondola n'kovuta kukwaniritsa nthawi imodzi, komabe mafakitale omwe amagwiritsa ntchito pipettes amafuna zonse zolondola komanso zolondola. M'malo mwake, ndi mulingo wapamwamba kwambiri uwu womwe umapangitsa kuti zitheke kuberekanso zotsatira zoyeserera.
Mtima wa pipette iliyonse yamagetsi ndi galimoto yake, yomwe imakhudza kwambiri kulondola ndi kulondola kwa pipette, kuwonjezera pa zinthu zina zofunika monga kukula kwa phukusi, mphamvu ndi kulemera kwake. Akatswiri opanga ma Pipette amasankha ma stepper linear actuators kapena DC motors. Komabe ma stepper motors ndi ma DC motors ali ndi zabwino komanso zovuta zawo.
DC Motors
Ma motors a DC ndi ma mota osavuta omwe amazungulira mphamvu ya DC ikayikidwa. Safuna maulumikizidwe ovuta kuti injini iyende. Komabe, poganizira zofunikira zoyenda pamapipeti apamagetsi, mayankho amagalimoto a DC amafunikira zowongolera zowongolera ndi giya kuti atembenuzire kusuntha kozungulira ndikupereka mphamvu yofunikira. Mayankho a DC amafunikiranso njira yoyankhira ngati sensa ya kuwala kapena encoder kuti athe kuwongolera bwino momwe pistoni ilili. Chifukwa cha inertia yayikulu ya rotor yake, opanga ena amathanso kuwonjezera ma braking system kuti apititse patsogolo kulondola kwa malo.
Stepper motors
Kumbali inayi, mainjiniya ambiri amakonda ma stepper linear actuator mayankho chifukwa chosavuta kuphatikiza, magwiridwe antchito abwino komanso mtengo wotsika. Ma Stepper linear actuators amakhala ndi maginito okhazikika a magnet stepper motors okhala ndi ulusi wozungulira komanso cholumikizira chophatikizika kuti apange mizere yolunjika pamaphukusi ang'onoang'ono.
