Iingcebiso, njengezinto ezityiwayo ezisetyenziswa ngeepipettes, ngokubanzi zingohlulwa zibe: ①.Iingcebiso zesihluzi , ②.Iingcebiso ezisemgangathweni, ③.Iingcebiso ezisezantsi zentengiso, ④.Akukho mthombo wobushushu, njl.
1. Incam yokucoca iyinto esetyenziswayo eyenzelwe ukuphepha ukungcoliseka okunqamlezayo.Ihlala isetyenziswa kuvavanyo olufana nebhayoloji yemolekyuli, i-cytology, kunye ne-virology.
2. Ingcebiso esemgangathweni yeyona ngcebiso isetyenziswa kakhulu.Phantse yonke imisebenzi yokufaka imibhobho ingasebenzisa ingcebiso eqhelekileyo, eyona ndlela yoqoqosho lwetip.
3. Kwiimvavanyo ezineemfuno eziphezulu zovakalelo, okanye iisampulu ezixabisekileyo okanye i-reagents ekulula ukuhlala, unokukhetha i-tip ephantsi ye-adsorption ukunyusa izinga lokubuyisela.Umphezulu wencam ye-adsorption ephantsi uye wafumana unyango lwe-hydrophobic, olunokunciphisa ulwelo olusezantsi lwexinzelelo olushiya iintsalela ezininzi kwincam.(Umfanekiso awuphelelanga kwaye inkumbulo ilinganiselwe)
I-PS: Incam yomlomo obanzi ilungele ukufunxa izinto ezibonakalayo, i-DNA ye-genomic, kunye ne-cell culture fluid;
Iimpawu zokusebenza zengcebiso: i-adsorption ephantsi, into yokucoca, ukuqina, amandla okulayisha kunye nokukhupha, akukho DNase kunye ne-RNase, akukho pyrogen;
Indlela yokukhetha ingcebiso elungileyo?"Njengoko ingcebiso enokufakwa iyingcebiso enokusetyenziswa"
——Oku kuqondwa ngokubanzi phantse kubo bonke abasebenzisi ngokuguquguquka kwentloko yokufunxa.Le ngxelo inokuthiwa yinyani 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.Ukuphendula lo mbuzo kufuna idatha ukuthetha.
1. Unokuba unqwenela ukwenza uvavanyo lokusebenza emva kokufanisa i-pipette kunye nengcebiso.Emva kokucoca incam, yenza imisebenzi yokongeza iisampulu ephindaphindiweyo, ulinganise isixa sesampulu yokongeza ixesha ngalinye, kwaye urekhode ufundo.
2. Bala ukuchaneka kunye nokuchaneka kokusebenza kombhobho emva kokuguqula ibe yivolumu ngokobuninzi bovavanyo lolwelo.
3. Into ekufuneka siyikhethe yingcebiso echanekileyo.Ukuba ukuchaneka kwe-pipette kunye ne-tip ayilungile, kuthetha ukuba ukuqina kwe-tip kunye ne-pipette akunakuqinisekiswa, ukwenzela ukuba iziphumo zomsebenzi ngamnye azikwazi ukuveliswa kwakhona.
Ke ngawaphi amanqaku amancinci engcebiso elungileyo?
Ingcebiso elungileyo ixhomekeke ekugxininiseni, kwi-taper, kwaye eyona ngongoma ibalulekileyo yi-adsorption;
1. Makhe sithethe nge-taper kuqala: ukuba kungcono, umdlalo kunye nompu uya kuba kuhle kakhulu, kwaye i-liquid absorption iya kuchaneka ngakumbi;
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 yi-adsorptivity yethu: i-adsorptivity ihambelana nezinto eziphathekayo zengcebiso.Ukuba izinto ze-tip azilungile, ziya kuchaphazela ukuchaneka kombhobho, okubangelwa ukugcinwa kwamanzi amaninzi okanye isifinyezo Ukuxhoma eludongeni, kubangela iimpazamo kwipayipi;
Ngoko ke wonke umntu kufuneka ahlawule ngokukodwa kula manqaku mathathu angasentla xa ukhetha intloko yokufunxa
