Hauv peb cov kev sim tshuaj lom neeg, peb feem ntau siv PCR yim-tube centrifuge raj, tab sis cov raj centrifuge tuaj yeem muab faib ua cov raj centrifuge siab thiab cov raj centrifuge zoo tib yam. Dab tsi yog qhov txawv ntawm ob lub centrifuge raj thaum lawv siv?
1. High-speed PCR yim-tube centrifuge raj
1. Tsis txhob siv yam tsis muaj kev cob qhia thiab kev ntsuas.
2. Xaiv cov rotor haum thiab ceev, tsis txhob siv.
3. Xaiv qhov kub kom haum, feem ntau yog 4 degree, tsis qis dua cov organic hnyav kom tsis txhob khov thiab puas rau lub centrifuge raj thiab rotor.
4. Ua ntej siv lub rotor, so lub raj nrog lub qhov pas nrig thiab ua tib zoo tshuaj xyuas hauv qab ntawm lub qhov rau cov kab nrib pleb thiab cov pob dawb. Yog tias muaj, tig ib ncig thiab khawb.
5. Tus nqi ntawm cov tshuaj ntim rau hauv lub raj centrifuge yuav tsum tsim nyog. Lub raj stainless hlau tsis muaj npog thiab tuaj yeem haum 2/3 nkaus xwb. Cov raj yas tuaj yeem txuas rau lub xub pwg nyom. Lub hau yuav tsum raug kaw thiab tsis tso cai tawm. Cov hlab ntsha tuaj yeem deformed los ntawm centrifugation. Kev siv cov kuab tshuaj organic hauv cov raj yas yuav tsum ua raws li cov cai.
6. Cov raj centrifuge yuav tsum muab tso rau hauv khub thiab yuav tsum nruj nruj nrog qhov sib txawv ntawm<>
7. Tsis pub tig tsis tau tig. Txhawm rau tuav lub rotor, tus kov yuav tsum tau siv los tiv thaiv lub rotor los ntawm kev swb. Tig lub teeb taub hau thiab tuav nws ruaj khov. Thaum tig lub kov, tuav tus kov nrog koj txhais tes thiab tig koj lub taub hau. Lub taub hau taub hau yuav tsum kaw nruj nreem thiab lub hau yuav tsum tsis txhob tso centrifugation.
8. Tsis txhob qhib lub hau thaum centrifugation. Tsis muaj kev txhawb nqa centrifuges. Yog hais tias lub suab thiab kev co yog txawv txav, nres tam sim ntawd.
9. Tom qab siv lub rotor, nws yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm thiab qhuav nyob rau hauv lub rotor chamber, thiab lub raj lub qhov yuav tsum tau ua tib zoo ntxuav nrog ib tug pas nrig. Yog tias cov tshuaj nchuav, koj yuav tsum ntxuav nws, so lub condensation ntawm lub rotor chamber, thiab qhib lub qhov rooj kom qhuav lub rotor chamber.
10. Lub centrifuge yuav tsum tau khaws cia thiab yuav tsum tau sau npe tom qab siv.
2. Ordinary yim-tube centrifuge raj
1. Ua ntej tawm hauv lub centrifuge, ua tib zoo tshuaj xyuas txhua qhov hauv lub rotor rau cov khoom txawv teb chaws.
2. Lub raj centrifuge yuav tsum ua tib zoo sib npaug.
3. Yog hais tias lub cab tsis huv, kaw lub raj nrog cov yeeb yaj kiab yas.
4. Yuav tsum pib maj mam ua kom nrawm.
5. Tsis txhob qhib lub hau thaum centrifugation.
6. Tsis txhob siv lub tes tuav.
