I-Centrifugeingenye yemishini eyisisekelo evame ukusetshenziswa ezindaweni zokucwaninga, esetshenziswa kakhulu ezindaweni zokucwaninga zasesibhedlela.I-Centrifuge 10 iyithuluzi elibalulekile lokuhlukanisa i-serum, amaseli abambekayo agayiwe, ukuhlolwa kwe-PCR nokunye.I-centrifuge kagesi ehlakaniphile inomumo omuhle, umthamo omkhulu, usayizi omncane kanye nemisebenzi ephelele.Inezinzuzo zokusebenza okuzinzile, isivinini esilungisekayo kanye nebhalansi yokulungiswa okuzenzakalelayo, ukuphakama okuphansi kwezinga lokushisa, ukusebenza kahle okuphezulu nokusebenza okubanzi.Ugesi ohlakaniphilei-centrifugeilungele ukuhlaziywa kwekhwalithi ye-serum, i-plasma ne-urea emikhiqizweni yezokwelapha, eziteshini zegazi, ukuhlolwa kwemitholampilo kanye namalabhorethri amakhemikhali ezinto eziphilayo.

Khetha ama-centrifuges ajwayelekile, ngokuya ngosayizi womthwalo wokusebenza, ikakhulukazi ezicini ezimbili zejubane namandla.Imininingwane elandelayo ukuthengwa kwama-centrifuges anembile kufanele kunake izinkinga:

1. Isivinini
Ama-Centrifuges ahlukaniswe abe-low-speedama-centrifuges<10000rpm/min, isivinini esikhuluama-centrifuges10000rpm/min ~ 30000rpm/min, kanye ne-ultra-high-speed centrifuges>30000rpm/min ngokuya ngesivinini esiphezulu.I-centrifuge ngayinye inesivinini esilinganiselwe esiphezulu, futhi isivinini esiphezulu sibhekisela ejubaneni ngaphansi kwezimo zokungalayishi.Kodwa-ke, isivinini esiphezulu siyahlukahluka kuye ngohlobo lwe-rotor kanye nobukhulu besampula yesampula.Isibonelo, ijubane elilinganiselwe le-centrifuge liyi-16000rpm / min, okubonisa ukuthi i-rotor ijikeleza izikhathi ezingu-16,000 ngomzuzu lapho umthwalo ungalayishiwe, futhi isivinini ngokuqinisekile sizoba ngaphansi kuka-16000rpm / min ngemva kokwengeza isampula.I-rotor ehlukile, isivinini esiphezulu sihlukile;I-centrifuge engenisiwe ingakhethwa ngama-rotor amaningi, futhi abakhiqizi abambalwa bama-centrifuge asekhaya baye bathuthukisa ngempumelelo ubuchwepheshe obunjalo, obufana ne-TG16 desktop high-speed centrifuges, TGL16, TGL20 desktop high-speed centrifuges efrijini, kanye namanye amamodeli amaningi angenziwa. ilayishwe izinhlobo eziyi-16 zamarobhothi, angasetshenziswa emshinini owodwa.I-rotor enezingqimba ingafinyelela ku-15000rpm/min, kodwa i-Angle rotor ingafinyelela cishe ku-14000rpm/min, umehluko othize ukuze uthintane nabasebenzi bokuthengisa umkhiqizo kanye nabasebenzi abafanelekile bezobuchwepheshe besitshalo sokukhiqiza ngokuningiliziwe, ngakho-ke ukukhetha kwejubane kufanele kuqaphele, isivinini esiphezulu se-centrifuge ekhethiwe kufanele sibe ngaphezu kwejubane eliqondiwe.Isibonelo, uma ijubane eliqondiwe lingu-16000rpm/mIn, isivinini esiphezulu se-centrifuge ekhethiwe kufanele sibe ngaphezu kuka-16000rpm/min.Ngokuvamile, umphumela wokuhlukanisa ngokuyinhloko uncike esivinini, kodwa amandla e-centrifugal, ngakho ngezinye izikhathi isivinini asihlangabezani nezidingo, inqobo nje uma amandla we-centrifugal angafinyelela izinga, ukuhlolwa kungafinyelela umphumela owudingayo.

Ifomula yokubala amandla e-Centrifugal: I-RCF=11.2×R× (r/min/1000) 2 R imele irediyasi eyi-centrifugal, r/min imele isivinini

2. Izinga lokushisa
Amanye amasampuli anjengamaphrotheni, amaseli, njll. azobhujiswa endaweni yokushisa ephezulu, edinga ukukhetha okufriziwe.ama-centrifuges, ezinebanga lokushisa elilinganiselwe.I-Centrifuge ngesivinini esikhulu lapho kukhiqizwa ukushisa kanye nebhalansi yesistimu yesiqandisi se-centrifuge ezingeni lokushisa elithile, ngokuvamile amasampula e-centrifuge eqandisiwe adinga ukugcinwa ku-3 ° C ~ 8 ° C, inani elithile lingafinyelelwa futhi i-rotor, njenge-centrifuge ilinganiselwe. izinga lokushisa elingu--10 ° C ~ 60 ° C, faka i-rotor enezingqimba ingafinyelela cishe ku-3 ° C uma ijikeleza, Uma i-rotor eyi-angular, ingase ifinyelele cishe ku-7 ° C. Leli phuzu kufanele lithintane nabasebenzi bokuthengisa umkhiqizo. kanye nabasebenzi bezobuchwepheshe abafanelekile besikhungo sokukhiqiza ngokuningiliziwe.

3. Amandla
Mangaki amashubhu amasampula okufanele afakwe i-centrifuged ngesikhathi?Ishubhu ngayinye yesampula idinga umthamo ongakanani?
Lezi zici zinquma umthamo ophelele we-centrifuge, ukukhuluma nje, umthamo ophelele we-centrifuge = umthamo wethubhu ngalinye le-centrifugal × inani lamashubhu e-centrifugal, umthamo ophelele kanye nobukhulu bomthwalo womsebenzi kufaniswe.
