na o ka sebelisa centrifugation ho arola metsi le lehlabathe?

Selelekela

Ho centrifugation ke mokhoa o sebelisoang haholo mafapheng a fapaneng a saense o kenyeletsang ho arola metsoako ho latela bongata ba eona ho sebelisoa matla a centrifugal. Sehloohong sena, re tla hlahloba hore na ho centrifugation ho ka sebelisoa ka katleho ho arola metsi le lehlabathe kapa che. Re tla teba melao-motheong ea ho centrifugation, litšobotsi tsa metsi le lehlabathe, 'me re buisane ka liphephetso le litharollo tse ka bang teng bakeng sa ho arola lintho tsena tse peli ka katleho. Kahoo ha re qaleng!

Ho utloisisa Centrifugation

Pele o hlahloba karohano ea metsi le lehlabathe ka ho sebelisa centrifugation, ho bohlokoa ho utloisisa melao-motheo ea motheo ea mokhoa ona. Centrifugation e sebetsa ka ho potoloha sampole ka lebelo le phahameng, e leng se hlahisang matla a centrifugal a sutumetsang likaroloana ho li arola ho latela bongata ba tsona. Likaroloana tse boima li atisa ho leba moeling o ka ntle oa kamore ea ho phunya, ha likaroloana tse bobebe li ka lula li le haufi le bohareng.

Matlotlo a Metsi le Lehlabathe

Metsi, e leng motsoako oa bohlokoa le o akaretsang, a na le boima ba hoo e ka bang gram e le 'ngoe ka sentimetara ea cubic (g/cm³) mochesong oa kamore. Ke molek'hule ea polar, e leng se etsang hore e be mokhethoa ea babatsehang oa ho qhala le ho tsamaisa lintho tse fapaneng. Ka lehlakoreng le leng, lehlabathe le na le boholo ba silicon dioxide (SiO₂) 'me le na le boima bo phahameng haholo ha bo bapisoa le metsi, ka karolelano ea hoo e ka bang 2.65 g/cm³.

Mathata a ho Arohanya Metsi le Lehlabathe

Karohano ea metsi le lehlabathe e baka phephetso e kholo ka lebaka la phapang ea tsona ea bongata, kaha likaroloana tsa lehlabathe li teteaneng haholo ho feta metsi. Ha li kopantsoe, likaroloana tsa lehlabathe li atisa ho teba ka potlako, e leng se etsang hore mekhoa e tloaelehileng ea ho sefa kapa ho sefa e se sebetse. Ho sebetsana le bothata bona ho hloka ts'ebeliso ea centrifugation, har'a mekhoa e meng e ka bang teng, ho fihlela karohano e sebetsang hantle.

Ho Sebelisa Centrifugation bakeng sa ho Arola Metsi le Lehlabathe

Ho arola metsi le lehlabathe ka ho sebedisa centrifugation, ho hlokahala mehato e mmalwa ya bohlokwa. A re buisaneng ka mehato ena ka botlalo ka tlase.

1. Tokisetso ea Sampole

Motsoako oa metsi le lehlabathe o lokela ho lokisoa ka nepo pele o kenngoa ka har'a centrifugation. Mohato oa pele ke ho fumana sampole e tsoakiloeng hantle, ho netefatsa hore lehlabathe le ajoa ka ho lekana metsing.

2. Khetho ea Sentifuge

Ho kgetha centrifuge e loketseng ho bohlokwa ho fihlella karohano e sebetsang hantle. Centrifuge e lokela ho ba le bokgoni ba ho sebetsana le bophahamo ba sampole ha e ntse e fana ka matla a lekaneng a ho potoloha ho sutumelletsa dikarolwana tsa lehlabathe maboteng a tube kapa setshelo sa centrifuge.

3. Liparamente tsa Centrifugation

Ho fumana diparamente tse loketseng tsa ho centrifugation ho bohlokwa. Dintlha tse kang lebelo la ho centrifuge (dipotoloho ka motsotso, kapa rpm) le nako di bapala karolo ya bohlokwa ho aroleng metsi le lehlabathe ka katleho. Diteko di ka hlokahala ho ntlafatsa maemo a motswako o mong le o mong o ikgethang.

4. Ts'ebetso ea ho Centrifugation

Hang ha di-parameter tse ntle di se di hlalositswe, motswako o lokela ho kenngwa ka hloko ka hara diphaephe kapa dijana tse loketseng tsa centrifuge. Ho beha diphaephe ka sekhutlo ka hara rotor ya centrifuge ho ka thusa ho arola metsi le lehlabathe ka katleho.

5. Tlhahlobo ea Sephetho

Kamora ho centrifugation, hlahloba mekhahlelo e arohaneng ka har'a tube kapa setshelo. Haeba e atlehile, likaroloana tsa lehlabathe li tla kopanngoa hantle ho ea moeling o ka ntle ha metsi a ntse a le haufi le bohareng. Tlosa lera la lehlabathe ka hloko 'me u bokelle metsi a setseng, u phethe ts'ebetso ea karohano.

Qetello

Ka sebele ho centrifugation ke mokhoa oa bohlokoa oa ho arola metsi le lehlabathe. Ka ho sebelisa matla a centrifugal a hlahisoang nakong ea ho potoloha ka lebelo le phahameng, hoa khoneha ho arola lintho tsena tse peli ho latela phapang ea tsona ea bongata. Leha ho le joalo, ho na le mathata ka lebaka la bongata bo phahameng ba lehlabathe, ho khetha centrifuge e nepahetseng le ho ntlafatsa liparamente tsa centrifugation ho ka hlola litšitiso tsena ka katleho. Liteko tse ling li ka lebisa mekhoeng e ntlafetseng ea ho nolofatsa ts'ebetso ea karohano.
