Nekuwedzera kuziva kwekukanganisa kwezvakatipoteredza kwemarara epurasitiki uye mutoro wakawedzerwa une chekuita nekuraswa kwayo, pane dhiraivha yekushandisa yakadzokororwa pachinzvimbo chepurasitiki mhandara pese pazvinogoneka.Sezvo akawanda marabhoritari anoshandiswa akagadzirwa epurasitiki, izvi zvinomutsa mubvunzo wekuti zvinokwanisika here kushandura kumapurasitiki akadzokororwa murabhoritari, uye kana zvakadaro, zvinogoneka sei.
Masayendisiti anoshandisa zvigadzirwa zvepurasitiki mumhando dzakasiyana dzezvigadzirwa mukati nekutenderedza lab - kusanganisira machubhu (Cryovial tubes,PCR machubhu,Centrifuge tubes), Microplates(tsika ndiro,24,48,96 ndiro yakadzika tsime, PCR paltes), pipette mazano(Automated kana Universal matipi), petri ndiro,Reagent Mabhodhoro,nezvimwe.Kuti uwane mhedzisiro uye yakavimbika mhedzisiro, zvinhu zvinoshandiswa muzvinhu zvinodyiwa zvinofanirwa kunge zviri zvemhando yepamusoro kana zvasvika kune mhando, kuwirirana, uye kuchena.Mhedzisiro yekushandisa zvinhu zvisina mwero inogona kuve yakakomba: data kubva mukuyedzwa kwese, kana nhevedzano yezviedzo, inogona kushaya maturo nekutadza kumwe chete kutadza kana kukonzera kusvibiswa.Saka, zvinogoneka here kuzadzisa zviyero izvi zvakakwirira uchishandisa mapurasitiki akadzokororwa?Kuti tipindure mubvunzo uyu, tinofanira kutanga tanzwisisa kuti izvi zvinoitwa sei.
Mapurasitiki anogadzirwazve sei?
Pasi rose, kudzokororwazve kwemapurasitiki iindasitiri iri kukura, inosundwa nekuwedzera kuziva nezvekukanganisa kunoita tsvina yepurasitiki panharaunda yepasirese.Nekudaro, kune misiyano mikuru muzvirongwa zvekudzokorodza zvinoshanda munyika dzakasiyana, zvese maererano nechiyero uye kuuraya.MuGermany, semuenzaniso, chirongwa cheGreen Point, uko vagadziri vanobhadhara mari yekudzoreredza mapurasitiki muzvigadzirwa zvavo, chakaitwa kutanga muna 1990 uye kubva ipapo chakawedzera kune dzimwe nzvimbo dzeEurope.Zvakadaro, munyika zhinji chiyero chekudzokorodza mapurasitiki idiki, zvishoma nekuda kwezvinetso zvakawanda zvine chekuita nekugadzirisa kunoshanda.
Dambudziko rakakosha mukudzokorodza kwepurasitiki nderekuti mapurasitiki iboka rakasiyana-siyana remakemikari pane, semuenzaniso, girazi.Izvi zvinoreva kuti kuwana chinhu chinobatsira chakadzokororwa, tsvina yepurasitiki inoda kurongwa muzvikamu.Nyika dzakasiyana uye matunhu ane adzo masisitimu akamisikidzwa ekuisa muchikamu marara anogona kudzokororwa, asi mazhinji ane mutsara wakafanana wemapurasitiki:
- Polyethylene terephthalate (PET)
- High-density polyethylene (HDPE)
- Polyvinyl chloride (PVC)
- Low-density polyethylene (LDPE)
- Polypropylene (PP)
- Polystyrene (PS)
- Zvimwe
Pane misiyano mikuru mukureruka kwekudzokororwa kwezvikamu izvi zvakasiyana.Semuyenzaniso, mapoka 1 ne2 ari nyore kushandisa patsva, nepo 'rimwe' chikamu (boka 7) hachiwanzo shandiswa patsva5.Pasinei nenhamba yeboka, mapurasitiki akadzokororwa anogona kusiyanisa zvakanyanya kubva kune avo mhandara matauriro kana kuchena uye michina zvinhu.Chikonzero cheizvi ndechokuti kunyange mushure mekuchenesa nekugadzirisa, kusvibiswa, kana kubva kumarudzi akasiyana-siyana emapurasitiki kana kubva kune zvinhu zvine chokuita nekushandiswa kwekare kwezvinhu, zvinosara.Naizvozvo, mapurasitiki mazhinji (kusiyana negirazi) anongodzokororwa kamwe chete uye zvinhu zvakadzokororwa zvine maapplication akasiyana pane avo mhandara.
Ndezvipi zvigadzirwa zvinogona kugadzirwa kubva kumapurasitiki akadzokororwa?
Mubvunzo wevashandisi veLab ndewekuti: Zvakadini nezvekushandisa mulabhu?Pane here mikana yekugadzira mapurasitiki egiredhi-giredhi kubva kune zvakadzokororwa zvinhu?Kuti uone izvi, zvinodikanwa kuti titarise zvakanyanya kune izvo vashandisi vanotarisira kubva kune zvigadzirwa zvelab uye mhedzisiro yekushandisa zvisingaite.
Chinonyanya kukosha pane izvi zvinhu kuchena.Izvo zvakakosha kuti tsvina mupurasitiki inoshandiswa pakushandisa lab ideredzwe sezvo ichikwanisa kubuda kunze kwepolymer uye kuita sampuli.Izvi zvinonzi zvinobatika zvinogona kuve nemhando yezvisingafungidzirwe mhedzisiro, semuenzaniso, tsika dzemasero mhenyu, ukuwo ichipesvedzera maitiro ekuongorora.Nechikonzero ichi, vagadziri vezvekushandisa lab vanogara vachisarudza zvinhu zvine mashoma ekuwedzera.
Kana zvasvika kune mapurasitiki akadzokororwa, hazvibviri kuti vagadziri vaone kwakanyatsobva zvinhu zvavo uye saka zvinosvibisa zvingave zviripo.Uye kunyangwe vagadziri vakaisa simba rakawanda mukuchenesa mapurasitiki panguva yekudzokorodza, kuchena kwezvinhu zvakadzokororwa kwakadzikira zvakanyanya kupfuura mapurasitiki emhandara.Nechikonzero ichi, mapurasitiki akadzokororwa akanyatsokodzera zvigadzirwa izvo kushandiswa kwavo kusingakanganisike nehuwandu hwakaderera hwezvinobuda.Mienzaniso inosanganisira zvekuvaka dzimba nemigwagwa (HDPE), zvipfeko (PET), uye cushioning zvinhu zvekurongedza (PS)
Nekudaro, kune zvekushandisa lab, pamwe chete nezvimwe zvinonzwisisika zvikumbiro senge zvakawanda zvekudya-zvekubata zvinhu, kuchena nhanho dzeazvino maitiro ekudzokorodza haakwani kuvimbisa yakavimbika, inobereka mhedzisiro mulabhu.Pamusoro pezvo, kujeka kwakakwirira kwemaziso uye kuenderana kwemechanicha zvinhu zvakakosha mukushandiswa kwakawanda kwezvekushandisa lab, uye izvi zvinodikanwa hazvigutsikane kana uchishandisa mapurasitiki akadzokororwa.Naizvozvo, kushandisa zvinhu izvi kunogona kutungamira kune manyepo enhema kana zvakaipa mukutsvagisa, zvikanganiso mukuferefeta kweforensic, uye kuongororwa kusiri iko kwekurapa.
Mhedziso
Kudzokorodza kwepurasitiki inzira yakadzikwa uye iri kukura pasi rese iyo ichava nemhedzisiro yakanaka, inogara pazvakatipoteredza nekudzikisa tsvina yepurasitiki.Munzvimbo yerabhu, purasitiki yakadzokororwa inogona kushandiswa mumashandisirwo ayo asina kutsamira pakuchena, semuenzaniso kurongedza.Nekudaro, izvo zvinodikanwa zvekushandisa lab maererano nekuchena uye kuenderana hazvigone kuzadzikiswa neazvino maitiro ekudzokorodza, uye saka zvinhu izvi zvichiri kufanira kugadzirwa kubva mhandara mapurasitiki.
