I-Centrifuge Yahlula Izinto Ngokusekelwe Kubuninzi Bazo

Intshayelelo

Kwicandelo lesayensi nophando, iindlela ezahlukeneyo kunye nezixhobo ziye zaphuhliswa ukuze zahlulwe kwaye zihlalutywe izinto ezahlukeneyo. Phakathi kwezi ndlela, ukusetyenziswa kwe-centrifuge kuvelele njengendlela esebenzayo yokwahlula izinto ngokusekelwe kubuninzi bazo. I-centrifuge sisixhobo selabhoratri esisetyenziswa kakhulu esisebenzisa amandla e-centrifugal ukwahlula imixube eyahlukeneyo ngokufanelekileyo. Kweli nqaku, siza kuhlola imigaqo ye-centrifugation, ukusetyenziswa kwayo kwiindawo ezahlukeneyo, iintlobo ezahlukeneyo ze-centrifuges, ukubaluleka kwe-density gradient media echanekileyo, kwaye ekugqibeleni, amanyathelo okhuseleko ekufuneka aqwalaselwe xa uphatha esi sixhobo sinamandla.

Ukuqonda i-Centrifugation: Iziseko

I-Centrifugation yindlela yokwahlula esebenzisa umgaqo we-sedimentation. Xa umxube uphantsi kwamandla e-centrifugal, izinto ezixineneyo zidla ngokutsala i-sediment ngokukhawuleza kunezo zikhaphukhaphu. Olu kwahlula luququzelelwa kukuhamba okujikelezayo okwenziwa ngaphakathi kwe-centrifuge, nto leyo ebangela ukuba amandla e-centrifugal asebenze kwiisampuli.

Inceda ekwahlukaniseni izinto eziqinileyo kwizinto ezimanzi, iqinisekise ukuba kususwa ukungcola kunye nokufikelela kumgangatho ophezulu wemveliso.

3. Uhlalutyo Lwendalo: Ukucoca amanzi (centrifugation) kubaluleke kakhulu kuhlalutyo lwendalo. Kuvumela ukwahlulwa kwezinto eziqinileyo ezixhonyiweyo kwiisampuli zamanzi, kunceda ekumiseleni amanqanaba ongcoliseko nokuqinisekisa uvavanyo oluchanekileyo lwendalo.

4. Ishishini Lokutya Neziselo: Ishishini lokutya neziselo lisebenzisa kakhulu i-centrifugation ukwahlula izinto ezahlukeneyo ngexesha lenkqubo yemveliso. Isetyenziselwa ukwahlula amafutha, iiproteni, kunye nezinye iinxalenye ezingafunekiyo, nto leyo ekhokelela ekuphuculeni umgangatho wemveliso kunye nobomi obude beshelufu.

5. Ishishini lePetrochemical: Ukucoca i-centrifugation kudlala indima ebalulekileyo kwishishini lepetrochemical ngokwenza kube lula ukwahlula ioyile ekrwada ibe ziinxalenye ezahlukeneyo, ezifana nepetroli, idizili, izinto zokuthambisa, kunye neoyile yokufudumeza. Le nkqubo yokwahlula ibalulekile ekucoceni nasekuqinisekiseni umgangatho weemveliso zokugqibela.

Iintlobo ezahlukeneyo zeCentrifuges

1. Ii-Ultracentrifuges: Ezi zii-centrifuges ezinesantya esiphezulu ezikwaziyo ukufikelela kwisantya esiphezulu sokujikeleza, ngesiqhelo ziphakathi kwe-60,000 ukuya kwi-150,000 revolutions ngomzuzu (rpm). Zisetyenziselwa ukwahlula nokuhlola iimpawu zee-macromolecules ezifana ne-DNA, iiproteni, kunye nee-nanoparticles.

2. IiCentrifuge ezifakwe efrijini: IiCentrifuge ezifakwe efrijini zixhotyiswe ngeempawu zokulawula ubushushu, ezivumela ukucutshungulwa kweesampuli ezinobuzwelo kubushushu. ICentrifuge ebandayo inceda ukugcina ukuthembeka kweesampuli ngexesha leenkqubo zokwahlulwa.

3. Ii-Centrifuge zeBenchtop: Ezi centrifuge zincinci, ziyaphatheka, kwaye zifumaneka rhoqo kwiilebhu zophando. Zinika amandla aphantsi kodwa zinokuguquguquka kwaye zifanelekile kwiindidi ezahlukeneyo zokwahlulahlula rhoqo, kubandakanya ukulungiswa kwesampuli kunye nokuxilongwa kweklinikhi.

4. Ii-Microcentrifuges: Zenzelwe ngokukodwa ii-volumes ezincinci zeesampulu, ii-microcentrifuges zaziwa ngezakhono zazo ezikhawulezayo kunye ne-footprint encinci. Zihlala zisetyenziswa kwi-molecular biology nakwii-biochemistry laboratories ukuze kulungiselelwe isampuli ngokukhawuleza nangokufanelekileyo.

5. Ii-Centrifuge zokulungiselela: Ezi centrifuge zisetyenziswa xa kufuneka kucutshungulwe kwaye kwahlulwe inani elikhulu leesampuli. Zifumaneka rhoqo kwiindawo zoshishino kwaye zibonelela ngamandla aphezulu e-centrifuge kunye nomthamo omkhulu.

Ukubaluleka kweDensity Gradient Media

I-Density gradient media idlala indima ebalulekileyo kwinkqubo yokwahlulahlula ngaphakathi kwi-centrifuge. I-Density gradients ilungiswa ngokubeka izisombululo zoxinano olwahlukeneyo kwityhubhu ye-centrifuge. Xa isampuli ifakwa kwi-centrifugation, amasuntswana ahamba nge-density gradient phantsi kwempembelelo yamandla e-centrifugal. Le nkqubo iluncedo ngakumbi xa yahlula amasuntswana anoxinano olufanayo. I-Density gradients ivumela ukwahlula ngokuchanekileyo nangokufanelekileyo kweesampuli ngokwexinano zazo ezahlukeneyo.

Amanyathelo okhuseleko xa uphatha iiCentrifuges
