Ungakusebenzisa kanjani kahle ama-Pipete namathiphu

Njengompheki usebenzisa ummese, usosayensi udinga amakhono e-pipetting. Umpheki onamava angakwazi ukusika isanqante abe yiRibbons, abonakala engenawo umcabango, kepha akulimazi ukugcina imihlahlandlela ethile engqondweni - noma ngabe usosayensi. Lapha, ochwepheshe abathathu banikela ngamathiphu abo aphezulu.

UMagali Garia, uthi: "Umuntu kufanele aqaphele ukuba necebo elifanele lapho elahla ngesandla," kusho uMagali Gaillard, umphathi omkhulu, ukuphathwa kwePothifolio, umugqa webhizinisi le-MLH, uGilson (amaVilson (Villiers-Le-Bel, eFrance). "Amanye amaphutha ajwayelekile kakhulu we-Pipetting ahlobene nokusetshenziswa ngokunganaki kwamathiphu we-Pipette, isigqi esingahambisani nesikhathi, nokusingathwa okungafanele kwe-pipette."

Kwesinye isikhathi, usosayensi ukhethe i-pipette engalungile. NjengoRishi Porecha, Umphathi Wemikhiqizo Yomhlaba wonke ku-UbumbaAmathuluzi (Oakland, CA), athi, "Amanye amaphutha ajwayelekile ePipetting afaka phakathi ukungasebenzisi i-Pipette yevolumu efanelekile yomsebenzi othize nangokusebenzisa i-Pipette yokususa umoya ukuphatha uketshezi olungafanele." Ngamanzi e-viscous, i-Pipette ebabazekayo kufanele isetshenziswe njalo.

Ngaphambi kokuthola izinqubo ezithile zePipetting, kufanele kubhekwe eminye imiqondo ejwayelekile. "Njalo lapho abasebenzisi be-Pipette beqala umsebenzi wosuku, kufanele bacabangele ukuthi bakwenzani, yiziphi iziphuzo abasebenza nazo, nokuthi zifisa ukuthi ini zifisa ngaphambi kokukhetha i-pipette," kusho uPorecha. "Ngokoqobo, Azikho ilebhu enawo wonke amapayipi umsebenzisi angayifisa, kepha uma umsebenzisi ebheka ukuthi yiliphi amathuluzi atholakala kwilebhu nangomnyango, angathola umbono ongcono wokuthi ama-pipette akhona angawasebenzisa ngendlela ekhona noma ye Yimaphi ama-pipette angafuna ukuwathenga. "

Izici ezitholakala kuma-Pipette wanamuhla anweba ngaphezu kwensiza uqobo. Intuthuko ekusingatheni uketshezi senze ukuthi abasebenzisi manje baxhuma i-pipete yabo efwini. Ngalo xhuma, umsebenzisi angalanda ama-protocols noma adale ngokwezifiso. Idatha ye-Pipetting ingabanjwa ngisho nasefwini, iyiphi indlela eyodwa yokukhomba noma yiziphi izindlela ezingahambi kahle futhi zithuthukise inqubo yepayiphu, ikakhulukazi ngokulandela ukunemba okuqhubekayo, noma ukuntuleka kwayo.

Ngemishini efanelekile esesandleni, inselelo elandelayo ithola izinyathelo zesokudla.

Ukhiye wempumelelo

Nge-Pipette yokususa umoya, lezi zinyathelo ezilandelayo zandisa amathuba okulinganisa ngokunembile nangokuphindaphinda ivolumu ethile:

1. Setha ivolumu ku-pipette.
2. Cindezela i-plunger.
3. Gxila ngethiphu ekujuleni okulungile, okungahluka nge-pipette kanye nethiphu, futhi ngokushelela ukuvumela i-plunger iye esimweni sayo sokuphumula.
4. Linda cishe umzuzwana owodwa ukuze uketshezi lugeleze kuuthiphu.
5. Beka i-pipette ebanjwe ngama-degree angu-10-45 odongeni lwegumbi lokuthola, futhi ucindezela kahle i-plunger yokuma kokuqala.
6. Lindela umzuzwana owodwa bese ucindezela i-plunger kuya esitobhini sesibili.
7. Slayida ithiphu phezulu kodonga lomkhumbi ukuze ususe i-pipette.
8. Vumela i-plunger ukuthi ibuyele endaweni yayo yokuphumula.
