Izici zohlelo lokusebenza kanye nesiqondiso sokuthenga amashubhu e-centrifuge nama-centrifuges
Lesi sihloko sifinyeza ulwazi oluthile kuhlelo lokusebenza lokuhlukanisa, isiqondiso sokuthenga kanye nezincomo zomkhiqizo zamashubhu e-centrifuge, amashubhu e-ultrafiltration centrifuge kanye nama-centrifuge aselabhorethri, ngethemba lokuba usizo kuwe.
Ukumiswa kwesampula kufakwa esitsheni sesampula se-tubular.Ngaphansi kokujikeleza kwe-centrifuge ngesivinini esikhulu, izinhlayiya ezincane ezimisiwe (ezifana nemvula yama-organelles, ama-macromolecules yezinto eziphilayo, njll.) zihlala ngesivinini esithile ngenxa yamandla amakhulu we-centrifugal, ukuze zihlukaniswe nesixazululo.Lolu hlobo lwesitsha sesampula esishubhu esinekhava evalayo noma indlala lubizwa nge-centrifuge tube.
Izici zohlelo lokusebenza kanye nesiqondiso sokuthenga sezinto ezihlukahlukene zamashubhu e-centrifuge:
1. Ithubhu ye-Plastiki ye-centrifuge
Izinzuzo ze-plastic centrifuge tube zisobala noma zishintshashintsha, ubulukhuni bayo buncane, futhi isampula ingathathwa ngokubhoboza.Okubi ukuguquguquka okulula, ukumelana kabi nokugqwala kwe-solvent ephilayo nempilo yesevisi emfushane.
Amashubhu epulasitiki e-centrifuge wonke anamakepisi, asetshenziselwa ukuvimbela ukuvuza kwamasampuli, ikakhulukazi uma esetshenziselwa amasampula akhipha imisebe noma agqwala kakhulu;Isembozo seshubhu siphinde sisetshenziselwe ukuvimbela ukuvuthwa kwesampula nokusekela ithubhu ye-centrifuge ukuvimbela ukuwohloka kweshubhu le-centrifuge.Lapho ukhetha leli phuzu, naka ukuhlola ukuthi isembozo sepayipi siqinile yini, nokuthi singavaleka ngokuqinile yini ngesikhathi sokuhlolwa, ukuze ugweme ukuvuza okuwuketshezi uma kuhlanekezelwe.
Phakathi kwamashubhu epulasitiki e-centrifuge, izinto ezivamile ziyi-polyethylene (PE), i-polycarbonate (i-PC), i-polypropylene (PP), njll. Phakathi kwabo, amashubhu e-polypropylene PP asebenza kahle kakhulu.Ngakho-ke, sizama ukucabangela amashubhu e-polypropylene plastic centrifuge lapho sikhetha amashubhu epulasitiki e-centrifuge.Amashubhu epulasitiki e-centrifuge ngokuvamile ayizisetshenziswa zokuhlola ezilahlwayo, futhi ukusetshenziswa okuphindaphindiwe akunconywa.Ukuze wonge imali, amashubhu e-PP centrifuge angasetshenziswa kabusha njengoba kungenzeka, kodwa adinga ukufakwa inzalo ngokuphelele ngaphansi kwezinga lokushisa eliphezulu nokucindezela ukuze kuqinisekiswe imiphumela yesayensi yokuhlolwa.I-PE centrifuge tube ayikwazi ukuvalwa inzalo ngaphansi kwezinga lokushisa eliphezulu nokucindezela.
Amandla e-centrifugal umkhiqizo ongawathwala noma isivinini esinconyiwe sizoboniswa ngokuvamile ephaketheni noma emiyalweni yeshubhu lepulasitiki le-centrifuge.Ukuze kuqinisekiswe ukuphepha kokuhlolwa nokuthembeka kwemiphumela, ishubhu ye-centrifuge ehlangabezana nezidingo zesivinini sokuhlolwa kufanele kukhethwe.
2. Ithubhu ye-Glass centrifuge
Uma usebenzisa amashubhu engilazi, amandla e-centrifugal akufanele abe mkhulu kakhulu, futhi amaphedi enjoloba kufanele abekwe ukuvimbela amashubhu ukuthi angaphuli.Ama-centrifuges anesivinini esikhulu ngokuvamile awasebenzisi amashubhu engilazi.Uma ukuvalwa kwesembozo sethubhu ye-centrifuge kungalungile ngokwanele, uketshezi alukwazi ukugcwaliswa (kuma-centrifuges anesivinini esikhulu, ama-angle rotors asetshenziswa) ukuvimbela ukuchichima nokulahlekelwa ibhalansi.Umphumela wokuchichima ukungcolisa i-rotor ne-centrifugal chamber, okuthinta ukusebenza okuvamile kwe-inductor.Ngesikhathi se-ultracentrifugation, ithubhu ye-centrifuge kufanele igcwaliswe ngoketshezi, ngoba i-ultracentrifugation idinga i-vacuum ephezulu, futhi ukuguqulwa kwe-tube centrifuge kungagwenywa kuphela ngokugcwalisa.
3. I-centrifug yensimbi
Ishubhu yensimbi ye-centrifuge inamandla amakhulu, ayiwohloki, futhi imelana nokushisa, ukubanda kanye nokugqwala kwamakhemikhali.Ibuye isetshenziswe kabanzi, kodwa kufanele futhi igweme ukuthintana namakhemikhali anamandla agqwalayo, njengama-asidi aqinile nama-alkali.Zama ukugwema ukugqwala kwala makhemikhali.
