zingaki izinhlobo zomshini we-centrifuge

Imishini Yokucisha Ugesi: Umhlahlandlela Ophelele Wezinhlobo Nezinhlelo Ezihlukahlukene

Isingeniso

Imishini ye-Centrifuge iyimishini ebalulekile yelabhorethri esetshenziselwa ukuhlukanisa uketshezi nezinto eziqinile ngokusekelwe ekuhlukeni kobuningi bazo. Ithola ukusetshenziswa okubanzi kuzo zonke izimboni, okuhlanganisa ukunakekelwa kwezempilo, ucwaningo, imithi, kanye nesayensi yezemvelo. Lesi sihloko sinikeza umbono ophelele wezinhlobo ezahlukene zemishini ye-centrifuge, siqokomisa izici zayo ezihlukile, ukusetshenziswa, kanye nezinzuzo.

I. Izisekelo Zemishini Ye-Centrifuge

Imishini ye-Centrifuge isebenza ngesimiso samandla e-centrifugal, lapho i-rotor ejikelezayo idala insimu enamandla ye-centrifugal. La mandla abangela ukuthi izinhlayiya noma izinto ezisindayo zisuke phakathi nendawo, okuholela ekuhlukanisweni kwazo nezingxenye ezilula. Nazi izinhlobo eziyinhloko zemishini ye-centrifuge:

1.1. Ama-Centrifuge e-Angle Aqinile

Ama-centrifuge angama-fixed angle angenye yezinhlobo ezivame kakhulu, aklanywe nge-angle ye-rotor engaguquki ngokuvamile esukela kuma-degree angu-25 kuya kwangu-40. Alungele ukuhlukaniswa kwamavolumu amancane esampula futhi anikeza amazinga aphezulu okufakwa kwe-sedimentation. Lawa ma-centrifuge afanelekela umsebenzi ojwayelekile webhubhoratri futhi asetshenziselwa izinhlelo zokusebenza ezifana nokukhishwa kwe-DNA, ucwaningo lwamaprotheni, kanye nokuhlukaniswa kwamaseli.

1.2. Ama-Centrifuge ebhakede elijikayo

Ama-swinging bucket centrifuge afaka i-rotor yebhakede ehambayo eshintshashintsha isuka endaweni eqondile iye endaweni evundlile ngesikhathi sokusebenza. Lokhu kunyakaza kuthuthukisa ukuxubana kwamasampula futhi kuvumela ukuhlukaniswa kwamavolumu amakhulu amasampula. Ama-swinging bucket centrifuge avame ukusetshenziswa emabhange egazi, emalabhorethri okuxilonga, kanye nasezikhungweni zocwaningo lwezokwelapha.

1.3. Ama-Ultracentrifuge

Ama-Ultracentrifuge ayimishini ethuthukisiwe ye-centrifuge ekwazi ukufinyelela isivinini esikhulu sokujikeleza, evame ukwedlula i-100,000 RPM. Asetshenziswa kakhulu ekuhlukaniseni ama-macromolecule, amagciwane, kanye nezinhlayiya ezingaphansi kweseli ngokunemba okuhle kakhulu. Ama-Ultracentrifuge abalulekile emikhakheni yocwaningo lwesayensi njenge-molecular biology, i-biochemistry, kanye ne-virology.

II. Imishini Ekhethekile Ye-Centrifuge

2.1. Ama-Centrifuge Aqandisiwe

Ama-centrifuge afakwe esiqandisini anesistimu sokupholisa esakhelwe ngaphakathi evumela ukulawulwa okunembile kokushisa ngesikhathi sokucubungula isampula. Lawa ma-centrifuge abalulekile ezinhlelweni ezidinga amazinga okushisa aphansi, njengokulandelana kwe-DNA, ukuhlanzwa kwama-enzyme, kanye nomsebenzi wokukhulisa amaseli. Ukupholisa okulawulwayo kuvimbela ukuwohloka kwesampula futhi kugcina ubuqotho besampula.

2.2. Ama-Microcentrifuge

Ama-Microcentrifuge ayimishini emincane ye-centrifuge eyenzelwe ngqo ukuphatha amasampula amancane, ngokuvamile asukela ku-0.2 mL kuya ku-2 mL. Alungele ukusetshenziswa okubandakanya ama-microtubes, njengokuhlukaniswa kwe-DNA, ukusethwa kwe-PCR, kanye nokwehliswa kwamaprotheni. Ubukhulu bawo obuncane buwenza afanelekele ukusetshenziswa kokuhlolwa okuphathekayo kanye nokuhlolwa kwendawo yokunakekelwa.

2.3. Ama-Centrifuge Asheshayo

Ama-centrifuge anesivinini esikhulu aklanywe ukuze afinyelele futhi alondoloze isivinini esikhulu sokujikeleza, okwenza kube lula izikhathi zokuhlukana ezisheshayo. Le mishini isetshenziselwa izinhlelo zokusebenza eziningi, okuhlanganisa ucwaningo lwegciwane, ukuhlukaniswa kwamangqamuzana angaphansi, kanye nokuhlanzwa kwezinhlayiya ezincane. Ama-centrifuge anesivinini esikhulu anikeza ukusebenza kahle okuthuthukisiwe kanye nokukhishwa kwamasampula, okwenza abe yigugu emalabhorethri amaningi.

III. Izicelo Zemitholampilo Nezezimboni

3.1. Izimboni Zezokwelapha Nezokuxilonga

Emkhakheni wezokwelapha, imishini yokudonsa amanzi ibalulekile ekuhlaziyeni nasekuxilongeni izifo ezahlukahlukene. Ivame ukusetshenziswa emalabhorethri emitholampilo ekuhlolweni kwegazi, okuhlanganisa ukubalwa kwegazi okuphelele, ukuhlaziywa kwe-glucose, kanye nokuhlukaniswa kwe-serum. Ngaphezu kwalokho, ukudonsa amanzi emanzini kubalulekile ekuhlaziyeni uketshezi lomzimba, njengomchamo kanye noketshezi lwe-cerebrospinal, okusiza ekuxilongweni nasekuqapheni izifo.

3.2. Ukuthuthukiswa Kwemithi Nemithi

Imishini ye-Centrifuge idlala indima ebalulekile embonini yezemithi, isiza ekutholakaleni kwemithi, ukwakheka, kanye nokulawula ikhwalithi. Isetshenziselwa izinqubo ezifana nokuhlukaniswa kwezithako zemithi ezisebenzayo (ama-API), ukuhlanzwa kwamakhemikhali, kanye nokuhlolwa kokwakheka. I-Centrifugation isiza ososayensi ukufeza ukuhlukaniswa okunembile, okufaka isandla ekuthuthukisweni kwemithi okuphumelelayo kanye nokusebenza kahle okuthuthukisiwe.

3.3. Isayensi Yezemvelo

Imishini ye-Centrifuge isetshenziswa kakhulu kwisayensi yezemvelo kanye nocwaningo, ikakhulukazi ekwelapheni nasekuhlaziyeni amanzi angcolile. Ngokuhlukanisa izinto eziqinile ezilengisiwe emanzini angcolile, ama-centrifuge anegalelo ekususweni kokungcola, aqinisekise ukuthi imithombo yamanzi ihlanzekile. Ngaphezu kwalokho, ayasiza ekuhlaziyweni kwamasampula enhlabathi, ekufundeni amaphethini okungcola, kanye nokuqapha ukungcola kwemvelo.

IV. Izinzuzo Zemishini Ye-Centrifuge

4.1. Ukusebenzisa Isikhathi Kahle

Imishini ye-Centrifuge inikeza ukuhlukaniswa okusheshayo, okunciphisa kakhulu izikhathi zokucubungula uma kuqhathaniswa nezindlela ezenziwe ngesandla. Lokhu kusebenza kahle kwesikhathi kubalulekile ezinhlelweni zokusebenza ezithinta isikhathi noma amalabhorethri aphezulu, okuvumela ukuhlaziywa okusheshayo kanye nenqubekela phambili yocwaningo.

4.2. Ukunemba Okuthuthukisiwe

I-Centrifugation inikeza imiphumela enembe kakhulu, iqinisekisa ukuhlukaniswa okunembile kwezingxenye ezahlukene. Umehluko ocacile phakathi koketshezi nezinto eziqinile ezitholakala nge-centrifugation uthuthukisa ukuthembeka kokuhlolwa kwelabhorethri kanye nokuhlolwa kokuxilonga.

4.3. Ukuguquguquka

Imishini ye-Centrifuge ingamathuluzi ahlukahlukene akwazi ukwamukela osayizi abahlukahlukene besampula kanye nobuningi. Njengoba inezinhlobonhlobo zama-rotor nama-adapter, ingazivumelanisa nezidingo zocwaningo ezahlukahlukene, okwenza ibe yinto ebalulekile emalabhorethri amaningi.

4.4. Isampula Yokulondolozwa

Inqubo yokulawula i-centrifugation isiza ekulondolozeni ubuqotho bamasampula abucayi. Ngokuhlukanisa ngokucophelela izingxenye ngokusekelwe ekubuneni, amasampula agcina izakhiwo zawo zokuqala futhi afanelekela ukuhlaziywa okwengeziwe noma ukugcinwa.

Isiphetho

Imishini ye-Centrifuge iyithuluzi elibalulekile lelebhu elisetshenziswa emikhakheni eyahlukene, enikeza ukuhlukaniswa okuthembekile kanye nokuhlaziywa kwezinto ezahlukene. Ukuqonda izinhlobo ezahlukene zemishini ye-centrifuge etholakalayo, ukusetshenziswa kwayo, kanye nezinzuzo ezihlobene nayo kuvumela abacwaningi nochwepheshe ukuthi bathuthukise ukusetshenziswa kwayo, bathuthukise umkhiqizo kanye nemiphumela yocwaningo.
