indlela yokwahlula ukhilimu kubisi nge-centrifugation ncert

Intshayelelo:

I-Centrifugation yindlela esetyenziswa kakhulu kwiindawo ezahlukeneyo, kuquka neshishini lobisi. Idlala indima ebalulekileyo ekwahlukaniseni ukhilimu nobisi, nto leyo ephumela kwiimveliso ezinamafutha ahlukeneyo. Kweli nqaku, siza kujonga inkqubo yokwahlula ukhilimu nobisi sisebenzisa i-centrifugation njengoko kuchaziwe kwiBhunga leSizwe loPhando lwezeMfundo noQeqesho (NCERT). Siza kuhlola isayensi engasemva kwe-centrifugation, amanyathelo abandakanyekayo, izinto ezichaphazela ukwahlukana, kunye nokubaluleka kokwahlulwa kwekhilimu kwimveliso yeemveliso zobisi.

I. Ukuqonda i-Centrifugation:

I-Centrifugation yinkqubo ebandakanya ukwahlulahlula izinto ngaphakathi komxube ngokusekelwe kumahluko wazo wobuninzi. Xa ubisi lujikeleziswa ngokukhawuleza kwi-centrifuge, amasuntswana ekhrimu axineneyo aphuma ngaphandle, ngelixa ubisi olukhaphukhaphu luhlala lusondele embindini. Olu kwahlukana luququzelelwa ngamandla e-centrifugal aveliswa kukujikeleza.

II. Inkqubo yeCentrifugation:

Ukwahlula ukhilimu kubisi kusetyenziswa i-centrifugation, la manyathelo alandelayo adla ngokubandakanyeka:

1. Ubisi olufudumeleyo: Ubisi luqala lufudunyezwe lufikelele kubushushu obuthile. Oku kunceda ukuphazamisa naziphi na iiqoqo ze-globule zamafutha endalo ezikhoyo, okuvumela ukwahlukana kube lula.

2. Zalisa i-centrifuge: Ubisi olufudumeleyo lufakwa kwizikhongozeli ze-centrifuge. Kufuneka kuqatshelwe ukuba ungawuxini kakhulu umatshini, kuba oku kunokuchaphazela ukusebenza kakuhle kokwahlulwa.

3. Ukucoca nge-centrifuge: Izikhongozeli ezilayishiweyo zifakwa kwi-centrifuge kwaye zijikelezwe ngokukhawuleza. Amandla e-centrifugal avelisiweyo abangela ukuba amasuntswana ekhrimu axineneyo ahambe aye eludongeni lwangaphandle lwesikhongozeli, ngelixa ubisi luhlala luphakathi.

4. Ukuqokelelwa kwekhrimu: Nje ukuba inkqubo yokucoca i-centrifugation igqityiwe, ikhrimu iqokelelwa ngononophelo ukusuka phezulu kwisikhongozeli. Le krimu idla ngokuba nepesenti ephezulu yamafutha kunobisi olwalulayishwe ekuqaleni.

III. Izinto Ezichaphazela Ukwahlulwa kweKrimu:

1. Ubungakanani bamafutha obisi: Ubungakanani bamafutha obisi buchaphazela ngokuthe ngqo ubungakanani kunye nomgangatho wekhrimu efunyenweyo. Ubisi olunamafutha amaninzi luvelisa ikhrimu enepesenti enkulu yamafutha.

2. Isantya kunye nexesha le-Centrifuge: Isantya kunye nobude be-centrifuge zichaphazela ukusebenza kakuhle kokwahlulwa kwekhrimu. Kufuneka kumiselwe useto olufanelekileyo kwiintlobo ezahlukeneyo zobisi kunye neemveliso zekhrimu ezifunwayo.

3. Ubushushu: Ubushushu apho inkqubo yokwahlulwa kwenzeka khona buchaphazela ukuxinana kwekhrimu kunye nokulula kokuhlukana. Ubushushu obuthile bunokuvelisa iziphumo ezingcono ngenxa yotshintsho kwiipropati zeglobule yamafutha.

4. Izinga lokujikeleza: Izinga apho i-centrifuge ijikeleza khona lidlala indima ebalulekileyo ekuhlukaniseni. Izinga lokujikeleza eliphezulu kakhulu okanye eliphantsi kakhulu linokuchaphazela isivuno sekhrimu, umgangatho, kunye nozinzo.

5. Uyilo lweCentrifuge: Uhlobo kunye noyilo lweCentrifuge esetyenzisiweyo luchaphazela inkqubo yokwahlula. Izinto ezifana nokuma kwesikhongozeli, umthamo, kunye noyilo lwerotor zimisela ubungakanani bokwahlulwa kwekhrimu.

IV. Ukubaluleka koKwahlulwa kweKrimu:

Ukwahlulwa kwekhrimu linyathelo elibalulekileyo ekuvelisweni kweemveliso zobisi ezahlukeneyo. Ezinye zezicelo eziphambili ziquka:

1. Ukuveliswa kwebhotolo: Ikhrimu ehlukanisiweyo nobisi isetyenziswa njengesithako esiphambili ekuvelisweni kwebhotolo. Ngokuyixuba ikhrimu, amaqhekeza amafutha ayahlangana aze enze ibhotolo.

2. Ukwenziwa kweedizethi ezisekelwe kwikhrimu: Ukwahlulwa kwekhrimu kunceda ekufumaneni ikhrimu enamafutha ahlukeneyo afunekayo ekuveliseni iidizethi ezifana nee-ayisikhrimu, iikhrimu ezityumkileyo, kunye neekhastadi.

3. Ukuveliswa kobisi olunamafutha aphantsi: Emva kokwahlulwa kwekhrimu, ubisi oluseleyo lunokulungiswa ngakumbi ukuze kuveliswe ubisi olunamafutha aphantsi, olunamafutha aphantsi. Lusetyenziswa njengendlela enempilo kwiimveliso ezahlukeneyo zokutya.

4. Iimveliso zobisi ezenzelwe wena: Ukwahlulwa kwekhrimu kunika ukuguquguquka ekuveliseni iimveliso zobisi ezinamafutha athile, okubonelela ngokukhethwa ngabathengi kunye neemfuno zokutya.

Isiphelo:

Ukucoca ubisi yindlela exabisekileyo yokwahlula ukhilimu kubisi kwishishini lobisi. Le nkqubo ivumela ukuveliswa kweemveliso zobisi ezahlukeneyo ezinamafutha ahlukeneyo, zilungele iimfuno zabathengi ezahlukeneyo. Ukuqonda isayensi emva kokucoca ubisi, ukulandela inkqubo efanelekileyo, kunye nokuqwalasela izinto eziphambili ezichaphazela ukwahlula ubisi kubalulekile ukuze kufunyanwe iziphumo ezilungileyo. Ngokusebenzisa izikhokelo ze-NCERT kunye nokubandakanya uphuhliso lwetekhnoloji, ishishini lobisi liyaqhubeka nokuphucula iindlela zokwahlula ubisi ukuze kuphuculwe ukusebenza kakuhle kunye nomgangatho wokwenziwa kweemveliso zobisi.
