Elabhoratri, izigqibo ezinzima zenziwa ukufumanisa ukuba kungcono kangakanani ukwenza uvavanyo olunzulu kunye novavanyo. Ixesha elingaphezulu, iingcebiso zepatte zilungelelaniswe ukuze zilungele i-labs kwihlabathi liphela kwaye zibonelela ngezixhobo zokuba oochwephesha kunye nezazinzulu banakho ukwenza uphando olubalulekileyo. Oku kuyinyani ngakumbi njengoko iCoVid-19 iyaqhubeka nokusasazeka kuyo yonke iUnited States. Iingcali ze-pidemiologists kunye noochwephesha be-virologists basebenza kwiwotshi ukuba baze nonyango lwentsholongwane. Iingcebiso ezityhidiweyo zemibhobho eyenziwe ngeplastiki zisetyenziselwa ukufundisisa intsholongwane kunye ne-bulky, i-pipette yeglasi ngoku ixhele kwaye izenzekelayo. Iyonke i-10 yeengcebiso zeplastiki zeplastiki zisetyenziselwa ukwenza uvavanyo olunye lwe-pied-19 okwangoku kwaye uninzi lweengcebiso ezisetyenzisiweyo ngoku zinesihluzo kuzo ezimelwe ukuba zithintele i-100% ye-aerosols kwaye ithintele ungcoliseko lwesampulu xa idluliselwa kwisampulu. Kodwa zingakanani ezi cebiso ezixabisa kakhulu kwaye okusiindawo eziyingqolowa zinceda kakhulu amalebs kwilizwe liphela? Ngaba i-labs ithathe isigqibo sokuphelisa isihluzi?
Kuxhomekeka kuvavanyo okanye uvavanyo oluzandleni, iilebhu kunye namaziko ophando aya kukhetha ukusebenzisa nayiphi na icebiso elingafakwanga okanye lemibhobho. Uninzi lweelebhu zisebenzisa iingcebiso ezincitshisiweyo kuba zikholelwa ukuba iifilitha ziya kuthintela zonke ii-aerosols ezivela kwisampulu. Iifilitha zihlala zibonwa njengeendlela ezisebenza kakuhle zokuphelisa ngokupheleleyo ukungqubana kwezinto ezivela kwisampulu, ngelishwa oku akunjalo. I-Polythylene Pipette I-Pipette Chot ASIT AKUFUNI UKUKHUSELEKO, kodwa endaweni yoko kucothisa ukusasazeka kweendlela ezingcolisayo.
Inqaku le-biix yakutshanje ithi, "[ILizwi] isithintelo liyinto entle kakhulu kwezinye zezi ngcebiso. Kuphela ziingcebiso eziphezulu kuphela ezibonelela ngesithintelo sokutywina. Uninzi lweefilotha zicothise ulwelo ukuba ungangeni kwi-pipette barrel. " Izifundo ezizimeleyo zenziwe zijonga ezinye iindlela zokucoca iifiliki kunye nokusebenza kwazo kuthelekiswa neengcebiso ezingezizo. Inqaku elapapashwa kwijenali ye-microbiology ye-microbiology, eLondon (1999) yafunda ukusebenza kweengcebiso ze-polyethylene xa ifakwe kwisiphelo se-PIPTE COP. Kuvavanyo ezingama-2620, iipesenti ezingama-20 zeesampulu zibonise ungcoliseko lwempumlo xa kwakusetyenziswa isihluzo se-Poalthylene (Pe). Isifundo sikwakufumanisa ukuba xa i-radiound i-radious okanye i-DADMID DNA yayingumbhobho osetyenziswayo akukho filtha, ungcoliseko lwe-pupettor yenzeka ngaphakathi kwe-100 yemiphetho. Oku kubonisa ukuba nangona iingcebiso ezihlanjululwayo zinciphisa inani lokungcoliseka komnqamlezo ukusuka kwenye i-pipette timp ukuya kwenye, iifilitha aziyeki ukungcolisa ngokupheleleyo.
