Li-tubes tsa Centrifuge:li sebelisetsoa ho ba le maro nakong ea centrifugation, e arolang sampole ka likarolo tsa eona ka ho e potoloha ka potlako ho potoloha axis e tsitsitseng.E fumaneha ka sekoahelo se tiisang kapa tšoelesa.Ke teko e tloaelehileng e ka sebelisoang ka laboratoring.
1. Ho ea ka boholo ba eona
E kholo ea centrifuge tube (500ml, 250ml, Normal centrifuge tube (50ml, 15ml), Micro-centrifuge tube (2ml, 1.5ml, 0.65ml, 0.2ml)
2. Ho ea ka sebōpeho sa tlase
Conical bottom centrifuge tube, sephara se sephara sa centrifuge, tube e chitja ea centrifuge e tlase
3. Ho ea ka tsela eo sekwahelo se koetsoeng ka eona
Gland centrifuge tube: tube ea centrifuge e koalang ka mochine oa khatiso, e atisang ho fumanoa ka har'a li-microcentrifuge tubes.
Screw cap centrifuge tube: kenyelletsa likatiba tse bataletseng (kaholimo ho kepisi e bataletse) le likatiba tsa plug (kaholimo ho kepisi ho na le sebopeho sa plug)
4. Ho ea ka thepa: tube ea centrifuge ea polasetiki, khalase ea centrifuge tube, tšepe ea centrifuge tube
1) Steel centrifuge tube: Thepa ea tšepe ea centrifuge e na le matla a phahameng, ha e na deformation, ho hanyetsa mocheso, ho hanyetsa serame le lik'hemik'hale tsa corrosion.E boetse e sebelisoa haholo, empa hape e lokela ho qoba ho kopana le lik'hemik'hale tse matla tse senyang, tse kang acid e matla le alkali e matla.Leka ho qoba ho bola ha lik'hemik'hale tsena
2) Glass centrifuge tube: Ha u sebelisa li-tubes tsa khalase, matla a centrifugal ha aa lokela ho ba a maholo haholo, 'me ho hlokahala liphaephe tsa rabara ho thibela li-tubes ho senya.Ka kakaretso, li-tubes tsa khalase ha li sebelisoe li-centrifuges tse lebelo le phahameng.Sekoahelo sa tube ea centrifuge ha se koaloe ka ho lekaneng, 'me mokelikeli o ke ke oa tlatsoa (bakeng sa li-centrifuges tse lebelo le li-angle rotor li sebelisoa) ho thibela ho phalla le ho lahleheloa ke tekanyo.Liphello tsa ho qhala ke ho silafatsa rotor le kamore ea centrifugal, e amang ts'ebetso e tloaelehileng ea kutlo.Nakong ea ultracentrifugation, tube ea centrifuge e tlameha ho tlatsoa ka metsi, hobane ultracentrifugation e hloka vacuum e phahameng, 'me ho tlatsa feela ho ka thibela tube ea centrifuge hore e se ke ea senyeha.
3) Plastiki ea centrifuge tube: Molemo oa tube ea polasetiki ea centrifuge ke hore e na le pepenene kapa e feto-fetoha, boima ba eona bo nyenyane, 'me sampuli e ka ntšoa ka ho phunya.Phoso ke hore e bonolo ho holofala, e na le khanyetso e mpe ea kutu ho lihlapolli tsa lintho tse phelang, 'me e na le bophelo bo bokhuts'oane ba ts'ebeletso.Li-tubes tsa centrifuge tsa polasetiki li entsoe ka PP (polypropylene), PC (polycarbonate), PE (polyethylene) le lisebelisoa tse ling.Ts'ebetso ea pipe ea PP e batla e le betere.Plastiki ea centrifuge tube e pepeneneng kapa e feto-fetoha, 'me centrifugation ea sampole e ka bonoa ka mokhoa o hlakileng, empa e batla e le bonolo ho holofala ebile e na le khanyetso e mpe ea kutu ho li-solvents tsa organic, ka hona bophelo ba ts'ebeletso bo khuts'oane.
Se latelang ke kenyelletso e khutšoanyane ea boitsebiso bo bong le bo bong:
PP(polypropylene): e feto-fetoha, e na le lik'hemik'hale tse tsitsitseng le mocheso o tsitsitseng, empa e tla fetoha brittle mocheso o tlase, kahoo u se ke ua centrifuge ka tlase ho 4 ° C.
PC (polycarbonate): ponaletso e ntle, boima bo phahameng, bo ka hloekisoa ka mocheso o phahameng, empa ha bo hanyetsane le asiti e matla le alkali le lihlapolli tse ling tse kang joala.E sebelisoa haholo-holo bakeng sa ultra-high-speed centrifugation ka holimo ho 50,000 rpm.
PE (polyethylene): opaque.Ha e sebetsane le acetone, acetic acid, hydrochloric acid, joalo-joalo E batla e tsitsitse 'me e atisa ho nolofatsa mocheso o phahameng.
PA (polyamide): Boitsebiso bona ke polymer e entsoeng ka PP le PE, e feto-fetohang, e tsitsitseng haholo linthong tsa lik'hemik'hale, empa ha e hanyetsane le mocheso o phahameng.
PS (polystyrene): e pepeneneng, e thata, e tsitsitseng ho tharollo e mengata ea metsi, empa e tla silafatsoa ke lintho tse sa tšoaneng tse phelang, tse sebelisoang haholo bakeng sa centrifugation e tlaase, 'me ka kakaretso e sebelisoa bakeng sa tšebeliso ea nako e le' ngoe.
PF (polyfluorine): translucent, e ka sebelisoa ka mocheso o tlase, haeba tikoloho ea liteko e le -100 ℃ -140 ℃, u ka sebelisa tube ea centrifuge e entsoeng ka thepa ena.
CAB (Cellulose Butyl Acetate): e pepeneneng, e ka sebelisoa bakeng sa boikemisetso ba ho hlapolla li-acids, alkalis, letsoai, alcohols le sucrose.
