Murabhoritari, sarudzo dzakaoma dzinogara dzichiitwa kuti uone nzira yekuitisa bvunzo dzakakosha uye bvunzo. Nekufamba kwenguva, matipi epipette akachinjika kuti aenderane nemaLab pasi rese uye anopa maturusi kuitira kuti matekiniki nemasainzi vakwanise kuita tsvakiridzo yakakosha. Izvi ndezvechokwadi kunyanya sezvo COVID-19 iri kuramba ichipararira muUnited States. Epidemiologists uye virologists vari kushanda siku nesikati kuti vauye nemushonga wehutachiona. Mapipeti akasefa akagadzirwa nemapurasitiki anoshandiswa kudzidza hutachiona uye iyo yaimbove yakawanda, girazi pipettes ikozvino yakapfava uye otomatiki. Huwandu hwegumi epurasitiki matipi epipetti anoshandiswa kuita imwechete COVID-10 bvunzo parizvino uye mazhinji ematipi anoshandiswa ikozvino ane sefa mukati mawo anofanirwa kuvharira kunze zana reaerosols uye kudzivirira kusvibiswa kwemuchinjiko kana sampling. Asi matipi aya anodhura zvakanyanya uye anodhura zvakatipoteredza ari kunyatso batsira maLab munyika yose? MaLab anofanira kusarudza kusiya sefa here?
Zvichienderana nekuyedza kana bvunzo iripo, marabhoritari nenzvimbo dzekutsvagisa dzichasarudza kushandisa matipi asina kusefa kana kusefa. MaLab mazhinji anoshandisa matipi akasefa nekuti vanotenda kuti mafirita anodzivirira ese aerosols kubva pakusvibisa sampuli. Mafirita anowanzoonekwa seanodhura-inoshanda nzira yekubvisa zvachose zvisaririra zvetsvina kubva mumuenzaniso, asi zvinosuruvarisa kuti izvi handizvo. Polyethylene pipette tip filters haidziviri kusvibiswa, asi panzvimbo iyo inongoderedza kupararira kwezvakasvibiswa.
Chinyorwa chazvino cheBiotix chinoti, "[izwi] chipingamupinyi ishoko risiri remamwe emazano aya. Mamwe matipi epamusoro-soro chete anopa chivharo chechokwadi chekuisa chisimbiso. Masefa mazhinji anongononotsa mvura kuti isapinda mupipette barrel. Zvidzidzo zvakazvimiririra zvakaitwa zvichitarisa dzimwe nzira dzetip mafirita uye kushanda kwawo zvichienzaniswa neasiri-sefa matipi. Chinyorwa chakaburitswa muJournal of Applied Microbiology, London (1999) yakadzidza kushanda kwepolyethylene sefa matipi payakaiswa mumagumo epipetti tip cone kuvhurwa zvichienzaniswa neasina kusefa matipi. Kunze kwe2620 miedzo, 20% yemasampuli yakaratidza kusvibiswa kwekutakura pamhino yepipettor pasina sefa yakashandiswa, uye 14% yemasampuli yakasvibiswa pakashandiswa polyethylene (PE) sefa tip (Mufananidzo 2). Chidzidzo ichi zvakare chakawana kuti kana mvura yeradioactive kana plasmid DNA yakaiswa pombi isingashandisi sefa, kusvibiswa kwepipettor barrel kwakaitika mukati me100 pipettings. Izvi zvinoratidza kuti kunyangwe iwo matipi akacheneswa achidzikisa huwandu hwekusvibiswa-kubva kune imwe pipette tipi kuenda kune imwe, mafirita haamise kusvibiswa zvachose.
