Litaba tsa polokeho ea lijo li amana le bophelo bo botle ba motho e mong le e mong, kahoo e 'nile ea e-ba sepheo sa sechaba kamehla.Haholo-holo lilemong tsa morao tjena, ka maemo a ruileng a batho le ntlafatso e tsoelang pele ea maemo a bophelo, tlhokahalo ea tlhahlobo ea lijo e ntse e eketseha.

Ha e le hantle, mosebetsi oa tlhahlobo ea lijo le ho latelloa ha lijo ka kakaretso o arotsoe ka mekhahlelo e 'meli: o mong ke oa lisebelisoa tsa likhoerekhoere, o mong ke oa lintho tsa boleng.

Mehato ea mantlha ea tlhahlobo ea polokeho ea lijo

Teko ea polokeho ea lijo ke ts'ebeliso ea likhopolo tsa mantlha le mekhoa ea tekheniki ho kenyelletsa fisiks, k'hemistri, biology le lithuto tse ling ho lekola, ho fumana le ho sekaseka metsoako ea mantlha, boemo le boemo ba microbiological ba lisebelisoa tse tala, lisebelisoa tse thusang, lihlahisoa tse felileng, lihlahisoa tse felileng. , le lihlahisoa.Mehato ea mantlha e kenyelletsa:

① Bokella lisampole: netefatsa sepheo sa tlhahlobo, etsa boholo ba liteko le lintho tse itseng tsa lisampole.

② Tokiso ea lisampole: Beha lisampole ka har'a libotlolo tse hloekileng tsa sampole, 'me u tšoaee libotlolo tsa mohlala ho latela linomoro tsa serial tse lisampoleng.Matšoao a entsoeng a lokela ho tseba ho tseba boemo ba tlhahlobo ea sampole.Lokisetsa mohlala pele ho ts'ebetso ho lokisa curve ea sampole le tharollo ea ho fumana sampole.

③Mehlala ea liteko: Ka thuso ea lisebelisoa tse amanang, li-reagents kapa litharollo tse tloaelehileng le tharollo ea liteko li tla lekoa ka nako e le 'ngoe.Ka mor'a ho bala liphetho tsa liteko le ho fumana litlaleho tsa pele, tlaleho ea tlhahlobo e ka ngoloa.

Ts'ebetsong ena, metsi, li-reagents le lisebelisoa tsa khalase li phetha karolo e fapaneng.

Metsi: Metsi a hloekileng a lokisitsoeng ka ho khetheha le metsi a silafalitsoeng ke ntho ea bohlokoahali ts'ebetsong ea tlhahlobo ea lijo.Ka lintho tse akaretsang tsa liteko, joalo ka tokiso ea reagent le sethala sa tlhahlobo, sebelisa metsi a tloaelehileng a silafetseng joalo ka khetho ea mantlha.Ho bohlokoa ho hlokomela hore ha ho etsoa qeto ea lintlha tse ling, maikutlo a metsi a hloekisitsoeng a hloka ho sebetsoa hape pele a ka kena mohatong o latelang oa tlhahlobo ea lijo.

Li-reagents: Li-reagents tekong li lokela ho sebelisoa ka mokhoa o utloahalang ho ama ka kotloloho mahlale le ho nepahala ha liphetho tsa tlhahlobo ea lijo.Tlhokomelo e khethehileng e lokela ho lefshoa ho bophelo ba sethala sa lik'hemik'hale tsa lik'hemik'hale.Tlhokomelo le boleng li hloka ho lekanyetsoa khafetsa, 'me tšebeliso ea li-reagents tsa lik'hemik'hale tse felloang ke nako e thibetsoe, ho seng joalo e tla ama ho nepahala ha phello ea ho lemoha.Ntle le moo, ho fana ka tharollo ho latela lintlha tse nepahetseng ho ka fokotsa kotsi ea ho hloleha ha reagent.

Glassware: Hona joale, libotlolo tsa khalase kapa lihlahisoa tsa polyethylene li sebelisoa haholo-holo lijaneng tsa liteko tsa lijo, tse ka sebelisetsoang ho boloka lithethefatsi, ho tsamaisa lithethefatsi le ho hlahloba lithethefatsi.Tse kang li-tubes tsa teko, li-beakers, li-flasks tsa volumetric, li-flasks tsa boima le li-flask tsa Erlenmeyer.Empa ntho ea bohlokoa ka ho fetisisa ke ho netefatsa hore bohloeki le bopaki ba ho lutla ha lijana tsena tsa khalase li lumellana le litekanyetso le litlhaloso tse nepahetseng.Ka hona, setshelo sa sehlahisoa sa tlhahlobo se tlameha ho hlatsuoa hantle le ho hloekisoa pele se sebelisoa ho netefatsa hore ha ho na litšila tse setseng.Karolo ea li-glassware e batla e le likarolong tsohle tsa bohlokoa tsa tlhahlobo ea lijo.
