Centrifuge raj yog ib hom tubular qauv thawv uas siv tshuab centrifugation los cais thiab npaj cov qauv lom.Lub zog centrifugal loj loj muab los ntawm kev sib hloov ceev ntawm lub centrifuge ua rau cov khoom me me hauv cov kua dej sib haum thiab sib cais los ntawm cov tshuaj.Lub raj centrifuge yog ua los ntawm cov khoom zoo pob tshab polymer polypropylene, uas yog dav siv nyob rau hauv ntau yam kev sim ua haujlwm thiab ua tau raws li qhov yuav tsum tau muaj ntawm kev txheeb xyuas qib roj ntsha.
Centrifuge technology:
Nws tau siv dav hauv kev tshawb fawb txog biological, tshwj xeeb tshaj yog nyob rau hauv biochemistry thiab molecular biology.Txhua chav kuaj biochemical thiab molecular biology yuav tsum npaj ntau hom centrifuges.Kev siv tshuab centrifuge feem ntau yog siv rau kev sib cais thiab kev npaj ntawm ntau yam kev kuaj lom.Cov qauv lom neeg raug tshem tawm yog muab tso rau hauv lub raj centrifuge nyob rau hauv kev sib hloov ceev.Vim yog lub zog centrifugal loj, cov khoom me me uas raug tshem tawm (xws li nag lossis daus ntawm cov organelles, lom macromolecules, thiab lwm yam) nyob ntawm ib qho ceev, kom lawv tuaj yeem sib cais los ntawm kev daws teeb meem.

Qhov laj thawj:
Thaum ib tug particle (biological macromolecule los yog organelle) raug rau centrifugal quab yuam nyob rau hauv high-speed rotation, lub centrifugal quab yuam "F" yog txhais los ntawm cov qauv hauv qab no, uas yog: F = ma = m ω 2 ra - acceleration ntawm particle rotation, m - qhov ua tau zoo ntawm kev sib hloov particle, ω — angular tshaj tawm ntawm particle rotation, r - vojvoog ntawm particle rotation (cm).Lub zog centrifugal feem ntau yog qhia los ntawm ntau yam ntawm lub ntiaj teb lub ntiajteb txawj nqus, yog li nws yog hu ua tus txheeb ze centrifugal force "RCF".Los yog muab tus lej los ntawm "g" los sawv cev, piv txwv li, 25000 × g.Nws txhais tau hais tias tus txheeb ze centrifugal quab yuam yog 25000.

Labio's centrifugal raj nta:
1. Qhov kub kam rau ua ntau yam yog - 80 ~ 121 ℃, uas tuaj yeem txhawb nqa qhov kub thiab txias kom tsis muaj menyuam;
2. Nruab nrab Zui loj xeem ceev 8500 RPM (r/min);
3. Kev ntsuas kub kub: tsis muaj dej xau thaum tig ntawm 65 ℃ rau 2 teev;
4. Lub raj phab ntsa yog du thiab pob tshab, uas yooj yim rau kev sim thiab kev soj ntsuam;
5. yeem γ Radiation sterilization.Qhov tshwj xeeb suav nrog 1.5ml / 2ml micro centrifuge raj thiab 15ml / 50ml centrifuge raj.Khoom siv: Polypropylene PP, cais raws li hauv qab tapered, ncig hauv qab thiab txhawb tus kheej hauv qab.
