Ese inama za Pipette ziyungurura zirinda rwose kwanduzanya kwanduza na aerosole?

Muri laboratoire, hafatwa ibyemezo bikomeye kugirango hamenyekane uburyo bwiza bwo gukora ibizamini bikomeye.Igihe kirenze, inama za pipette zahujwe na laboratoire kwisi yose kandi zitanga ibikoresho kuburyo abatekinisiye nabahanga bafite ubushobozi bwo gukora ubushakashatsi bwingenzi.Ibi ni ukuri cyane kuko COVID-19 ikomeje gukwirakwira muri Amerika yose.Epidemiologiste naba virologiste barimo gukora amasaha yose kugirango bazane imiti.Inama zungurujwe zakozwe muri plastiki zikoreshwa mukwiga virusi kandi rimwe na rimwe rinini cyane, ibirahuri byikirahure ubu biroroshye kandi byikora.Impanuro 10 zose za pulasitike zikoreshwa mugukora ikizamini kimwe cya COVID-19 kurubu kandi inama nyinshi zikoreshwa ubu zifite akayunguruzo muri zo ziteganijwe guhagarika 100% bya aerosole no kwirinda kwanduza umusaraba mugihe cyo gutoranya.Ariko ni bangahe izi nama zihenze cyane kandi zihenze kubidukikije zunguka laboratoire mugihugu cyose?Laboratwari ikwiye guhitamo gucukura akayunguruzo?

Ukurikije igeragezwa cyangwa ikizamini kiri hafi, laboratoire hamwe nibigo byubushakashatsi bizahitamo gukoresha inama zidashungura cyangwa zungurujwe.Laboratwari nyinshi zikoresha inama zungurujwe kuko zizera ko muyungurura izarinda aerosole zose kwanduza icyitegererezo.Akayunguruzo gakunze kugaragara nkuburyo buhendutse bwo gukuraho burundu ibimenyetso byanduye bivuye kurugero, ariko ikibabaje nuko ataribyo.Polyethylene pipette inama yo kuyungurura ntabwo ibuza kwanduza, ahubwo itinda gusa ikwirakwizwa ryanduye.

Ingingo ya Biotix iherutse igira iti: "[ijambo] inzitizi ni akantu gato ko kwibeshya kuri zimwe muri izi nama.Gusa inama zimwe-zohejuru zitanga inzitizi yukuri.Akayunguruzo kenshi gahoro gahoro gusa amazi yinjira muri barrique. ”Ubushakashatsi bwigenga bwakozwe harebwa ubundi buryo bwo gushungura no gukora neza ugereranije ninama zitayungurura.Ingingo yasohotse mu kinyamakuru cyitwa Microbiology Applied, London (1999) yize ku kamaro k'inama za filteri ya polyethylene iyo zinjijwe mu iherezo rya pipette tip cone ifungura ugereranije n'inama zitayungurujwe.Mu bizamini 2620, 20% by'icyitegererezo cyerekanye ko karryover yanduye ku zuru rya pipettor mugihe nta filteri yakoreshejwe, naho 14% by'icyitegererezo byandujwe igihe hakoreshejwe akayunguruzo ka polyethylene (PE) (Ishusho 2).Ubushakashatsi bwagaragaje kandi ko iyo ADN ya radiyo ikora cyangwa plasmid ADN yashizwemo hakoreshejwe akayunguruzo, kwanduza ingunguru ya pipine byabaye mu miyoboro 100.Ibi birerekana ko nubwo inama zayungurujwe zigabanya ingano yo kwanduzanya kuva kumutwe umwe ujya mubindi, muyungurura ntibihagarika kwanduza burundu.
