Ho khetha se nepahetsengTloaelo ea setsoe bohlokoa ho netefatsa liteko tse atlehileng litlhophisong tse fapaneng tsa laboratoring. Li-tubers tsa setso li sebelisoa haholo ho holisa likokoana-hloko, lisampole, kapa ho etsa tlhahlobo ea biochemical. Ka likhetho tse fapaneng, ho bohlokoa ho utloisisa litlhoko tse ikhethang tsa kopo ea hau. Tataiso ena e tla hlahloba lintlha tsa bohlokoa tseo re lokelang ho li khetha ha li khetha mahlako a setso, ho tsepamisa sebopeho ho hlahisa sebopeho, sebopeho sa boitsebiso le lits'ebetso tse sebetsang.
1. Moralo oa khoele
E 'ngoe ea maikutlo a sehlooho ha a khetha mohopolong oa setso ke mofuta oa sistimi ea ho koaloa. Li-Tube tse ngata tsa moetlo li bontša moralo o tloaelehileng oa khoele e tloaelehileng, joalo kaMekha e 13 mm kapa 16 le 16 mm. Moralo ona o lumellana le mefuta e fapaneng ea likokoanyana e fapaneng, e netefatsa boemo bo sireletsehileng bo thibelang tšilafalo ea mohlala le mouoane. Li-cap tsa pokello ea polasetiki li na le molemo haholo hobane li lekana ka thata mme li bonolo ho li sebelisa le maemong a sa tsoseheng.
Melemo:
Tiiso e sireletsehileng: ho thibela tšilafalo le tahlehelo ea mohlala.
Ho bonolo ho sebelisa: Ho nolofatsa ts'ebetso le ho fokotsa kotsi ea mafu.
Ho lumellana: E sebetsa ka lisebelisoa tsa laboratoring ea Standard laboratoring le ho koaloa.
2. Motsoako oa lintho tse bonahalang
Lintho tsa setso sa setso li na le tšusumetso e kholo ts'ebetsong ea eona le ho ikarabella bakeng sa ts'ebeliso e itseng. Thepa e atileng haholo e kenyelletsa:
Khalase ea borolicate
Khalase ea Borosilicate ke khetho e tsebahalang ea litso tsa setso ka lebaka la thepa ea eona e ntlehali:
Ho tsitsipaletsa ka lik'hemik'hale: khalase ea borolicate e loanela ho hlasela ha lik'hemik'hale, ho etsa hore e be e bolokehileng ea solven le reaching ntle le kotsi ea ho ipeha ha li-whinkants.
Ha a hanela mocheso o phahameng: Khalase ena e ka mamella lithemparetjha tse phahameng, e e etsa hore e be loketseng lits'ebetso tsa sterilization tse kang ho tsamaisa molumo.
Qoba ho makala a futhumatsang: khalase ea borolicate e ka mamella liphetoho tsa moea ntle le ho khaola kapa ho robeha.
Mefuta ena e etsa litso tsa litlolo tsa khalase tse bokoang haholo bakeng sa lits'ebetso tsa likokoana-hloko, lisele tsa lisele le lits'ebetso tse ling tsa laboratori moo litšebelisano tsa lik'hemik'hale li lokelang ho fokola.
Lithako tsa polasetiki
Ha khalase e fana ka melemo e mengata, li-tubes tsa polasetiki tse entsoeng ka thepa e kang polypropylene kapa polystyrene e boetse e sebelisoa haholo:
Lightweight le tse tšoarellang: Li-tubers tsa polasetiki ha li na mokhoa o fokolang oa ho ahla le li-tubes tsa khalase.
Ho sebetsa ka litšenyehelo: hangata e theko e phahameng ho feta likhetho tsa khalase, e loketseng lits'ebetso tsa litloholo tse phahameng.
Metsoako e sa Lakang: Li-tubers tse ngata tsa polasetiki li etselitsoe ho se khonehe, ho fokotsa kotsi ea tšilafalo.
Ho bohlokoa ho hlokomela, leha ho le joalo, polasetiki e kanna ea se fane ka maemo a ho hanyetsa ka lik'hemik'hale, haholoholo ka li-solvent tse mabifi.
3. Transpare e phahameng
Karolo e 'ngoe ea bohlokoa eo u lokelang ho e nahana ke tšitiso ea mohono oa setso. Ho pepesetsoa phahameng ho etsa bafuputsi ho bona boemo ba kholo ba setso ntle le ho bula tube. Karolo ena e nyatsa likopo tsa likokoana-hloko moo menyetla ea ho litšila e tla fokotsoa.
Melemo:
Ho lekola pono: Bokhoni ba ho bona kholo ea likokoana-hloko kapa sebopeho sa thekement ka nako ea nnete.
Ho fokotsa ho lumellana: ho fokotsa tlhoko ea ho bula tube bakeng sa tlhahlobo, ka ho etsa joalo.
4. Bophahamo le boholo
Li-Tubes tsa moetlo li tla ka boholo bo fapaneng le bokhoni, hangata bo tloha ho 5 ml ho isa ho 50 ml kapa ho feta. Ha u khetha mohopolong oa setso, nahana ka lintlha tse latelang:
Litlhokahalo tsa mohlala: Etsa bonnete ba hore bokhoni ba tube bo kopana le litlhoko tsa hau tsa liteko. Bakeng sa liteko tse nyane kapa tse fokolang tsa sampole, motsoako o nyane o ka lekana.
LITLHAKISO TSA BOPHELO: Etsa bonnete ba hore mothapo o khethiloeng o tšoana le lisebelisoa tsa hau tse teng tsa laboratori, tse kang li-racks kapa li-incubator.
5. Ho nahana ka kopo
Likopo tse fapaneng tsa laboratoring li ka hloka mefuta e khethehileng ea litlolo tsa setso:
Microbiology
Bakeng sa likopo tsa likopo tsa microbiology, joalo ka ho baatia kapa fungi:
Li-tubers tsa borolicate tsa khalase li khethoa le ho hanyetsa ha bona la lik'hemik'hale le bokhoni ba ho thibela lits'ebetso tsa sterilization.
Etsa bonnete ba hore li-tubes tseo u li khethileng li na le sistimi e tetetsoeng e thibelang ho thibela litšila.
Moetlo oa lisele
Liphohetso tsa moetlo oa lisele:
Ho hlaka haholo ho bohlokoa bakeng sa ho hlokomela molao oa sele.
Khetha li-tubes tse khanyang tse tlotsitsoeng tse tlotsitsoeng tse khokhothelang tse lokelang ho boloka ho hlakoloa nakong ea liteko.
Liteko tsa tikoloho
Bakeng sa tlhahlobo ea tikoloho:
Khetha li-tubes tsa setso tse ka emang tsa lik'hemik'hale tse ngata tse fumanehang mobung kapa tsa metsi.
Haeba boima le karohano ke lintho tse u tšoenyang nakong ea tšimo, nahana ka likhetho tsa polasetiki.
Sekhahla le thibelo ea litšila
Ha li sebetsana le likarolo tsa tlhaho, ho thetsoa hoa bohlokoa. Khetha li-tubes tsa moetlo tse khethiloeng kapa ho utloahala ho netefatsa hore li ke ke tsa hlahisa lisepo tsa batho ba sampole. Ntle le moo, nahana ka li-tubers tsa polasetiki tse lahlehang ha li sebetsana ho fokotsa kotsi ea tšilafalo.
Ho khetha tube e nepahetseng ea setso e hloka hore ho nahane ka hloko ka lintlha tse ngata, ho kenyelletsa le likarolo tsa meralo, ho na le litlhoko tsa lintho tse bonahalang, litlhokahalo tsa lintho tse loketseng le litlhoko tse khethehileng tsa kopo. Borosilicate setso ea moetlo oa li-tubes o fana ka botsitso bo boholo ba lik'hemik'hale, mocheso o phahameng oa khase. Ho sa le joalo, likhetho tsa polasetiki li fana ka pherekano e bobebe ebile e le chelete e theko e boima ea litlhophiso tse phahameng.
Ka ho utloisisa likarolo tsena tsa bohlokoa le ho li lihela ka litlhoko tsa hao tsa laboratori, u ka khetha li-tuber tsa hau tse loketseng ho ntlafatsa maemo a hau a liteko ha u ntse u boloka botšepehi le polokeho ea hae. Hore na o ntse o etsa lipatlisiso tsa likokoana-hloko kapa tlhahlobo ea tikoloho, tse ntseng li tsetela ka litumelo tsa boleng ba boleng li tla kenya letsoho haholo katleho ea mosebetsi oa hau oa laboratoring.
Bakeng sa tlhaiso-leseling e batsi ka li-tuuse tsa Cod le likopo tsa tsona ka tlhahlobo ea metsi, sheba sehlooho sena:"Tsela ea teko ea cod e sebelisoa joang tlhahlobong ea metsi."
