Iingcebiso, njengezinto ezisetyenziswayo kunye neepipettes, ngokuqhelekileyo zinokuhlulwa zibe iingcebiso eziqhelekileyo; iingcebiso ezihluziweyo;iingcebiso zokucoca ipayipi ye-conductive, njl.
1. Ingcebiso esemgangathweni yingcebiso esetyenziswa ngokubanzi.Phantse yonke imisebenzi yokubhobhoza ingasebenzisa iingcebiso eziqhelekileyo, ezona ndlela zifikelelekayo kwiingcebiso.
2. Ingcebiso ehluziweyo iyinto enokusetyenziswa ukuthintela ukungcoliseka kwaye isoloko isetyenziswa kwimifuniselo efana nebhayoloji yemolekyuli, i-cytology, kunye ne-virology.
3. Umphezulu we-low-adsorption tip uye wafumana unyango lwe-hydrophobic, olunokunciphisa ulwelo oluphantsi lwe-tension surface lushiya iintsalela ezininzi kwi-tip.
I-PS: Incam yomlomo obanzi ilungele ukufunxa imathiriyeli ye-viscous, i-genomic DNA, kunye ne-cell culture fluid.
Indlela yokukhetha i-pipetti efanelekileyo?
Ingxelo kunokuthiwa iyinyani kodwa ayiyonyani ngokupheleleyo.Iphuzu elinokuthi lifakwe kwi-pipette ngokwenene linokwenza inkqubo yepayipi kunye ne-pipette ukuqonda umsebenzi wepayipi, kodwa ngaba oku kunokwethenjelwa?Uphawu lombuzo luyafuneka apha.
Iimpawu zeengcebiso ze-pipette tip
Ke ngawaphi awona manqaku mancinci ekufuneka icebiso elilungileyo libe nawo?
Ingcebiso elungileyo ixhomekeke ekugxininiseni, kwi-taper, kwaye eyona ngongoma ibalulekileyo yi-adsorption;
1. Makhe sithethe nge-taper kuqala: ukuba kungcono, umdlalo kunye nepipette kuhle kakhulu.
2. I-Concentricity: I-Concentricity ingaba isangqa phakathi kwencam ye-tip kunye nekhonkco phakathi kwe-tip kunye ne-pipette yindawo efanayo.Ukuba ayililo iziko elifanayo, oko kuthetha ukuba ukugxila akukuhle;
3. Ekugqibeleni, eyona nto ibaluleke kakhulu kukuxhamla kwethu: i-absorptivity inxulumene nezinto eziphathekayo zengcebiso.Ukuba izinto ze-tip azilungile, ziyakuchaphazela ukuchaneka kwepayipi kwaye kubangele ukuba ubuninzi be-liquid bugcinwe okanye bubhekiselwe njengokuxhoma eludongeni, kubangela iimpazamo kwipayipi.
Ngoko ke wonke umntu kufuneka ahlawule ngokukodwa kula manqaku mathathu angasentla xa ukhetha i-pipette tip.Uluhlu lweengcebiso ezimbi lubekwe ngokucacileyo ngokwahlukileyo!Uya kubona ukuphambuka okucacileyo, kodwa eli linyathelo elibaluleke kakhulu ekukhetheni ingcebiso elungileyo.Kwakhona, nceda uqaphele ukufakwa kweengcebiso kwi-pipette ye-channel enye kunye ne-pipette ye-multi-channel ihluke.Kwitshaneli enye, faka incam ngokuthe nkqo kwincam yepipette, cinezela kancinci, kwaye uyijike kancinci ukuyiqinisa.Kwi-channel multi-channel, iziteshi ezininzi ze-pipette kufuneka zihambelane neengcebiso ezininzi, zifakwe kwi-angle, kwaye zigubungele kancane ngasemva nangaphambili ukuze ziqinise;Musa ukubetha ngokuphindaphindiweyo i-pipette ukuze uqinisekise ukungangeni komoya kwe-tip.
Ukuphendula lo mbuzo kufuna idatha ukuthetha
1. Tshatisa i-pipette kunye nengcebiso yokuvavanya ukusebenza.
2. Bala ukuchaneka kokusebenza kombhobho emva kokuyiguqula ibe yivolumu ngokobuninzi bovavanyo lolwelo.
3. Into ekufuneka siyikhethe kukuba nengcebiso elungileyo.Ukuba i-pipette kunye ne-tip ayihambelani kakuhle, ithetha ukuba ukuqina kwe-tip kunye ne-pipette ayinakuqinisekiswa, okwenza iziphumo zomsebenzi ngamnye zingenakwenzeka ukuvelisa.
