Yuav Ua Li Cas Xaiv Centrifuge Tubes
Lub raj centrifuge yog ib lub thawv qauv tubular nrog lub hau kaw los yog lub hau flip. Nws siv cov cuab yeej centrifugal los tsim kom muaj zog centrifugal thaum cov khoom tig los ntawm kev kub ceev, kom cov khoom tshem tawm uas muab tso rau hauv lub cev rotating yuav nyob los yog ntab, yog li ntawd qee cov khoom yog concentrated los yog sib cais los ntawm lwm cov khoom.
Raws li qhov loj ntawm lub centrifuge raj, nws feem ntau muab faib ua cov nram qab no specifications: 1.5mL, 2mL, 5mL, 10mL, 15mL, 50mL, thiab lwm yam. Cov raj centrifuge feem ntau muaj cov specifications, thiab feem ntau siv yog 10mL thiab 50 ml. Yog tias koj lub centrifuge yog nruab nrog 30mL lossis lwm yam tshwj xeeb ntawm cov raj centrifuge, koj yuav tsum xav txog kev xa khoom. Tsis tas li ntawd, cov raj centrifuge kuj tseem muaj cov hauv qab thiab cov hauv qab ntse, nrog rau cov ntsia hlau hau thiab ntsaws hau. Cov raj centrifuge nrog lub hau ntsia hlau muaj cov nplai zoo dua, thiab cov raj capped feem ntau tsuas yog muaj qhov ntsuas tag nrho.
Khoom siv ntawm yas centrifuge raj:
Tom qab ntawd raws li cov khoom sib txawv ntawm lub raj centrifuge, nws tuaj yeem muab faib ua cov yas thiab iav feem ntau. Muaj ntau yam khoom siv rau cov yas centrifuge raj, xws li PP, PC, PS, thiab lwm yam. Feem ntau hais lus, cov raj yas centrifuge siv ntau dua hauv chav kuaj, vim tias iav centrifuge raj tsis tuaj yeem siv rau hauv high-speed lossis ultracentrifuges. Hauv qab no yog cov lus qhia luv luv rau cov khoom siv thiab cov khoom ntawm cov yas centrifuge raj. Qhov kev xaiv tiag tiag yuav tsum yog raws li kev sib raug zoo ntawm cov khoom siv centrifugal thiab cov khoom siv centrifuge raj thiab qhov sib hloov ceev ntawm lub raj centrifugal. Kev xaiv dav:
PP (polypropylene): Translucent, zoo tshuaj thiab kub stability, tab sis yuav ua nkig ntawm qhov kub thiab txias, yog li tsis txhob qis dua 4 degree thaum centrifugation.
PC (polycarbonate): zoo pob tshab, siab tawv, tuaj yeem ua kom tsis muaj menyuam thaum kub, tab sis tsis tiv taus cov kua qaub thiab alkali thiab qee cov kuab tshuaj organic xws li cawv. Feem ntau yog siv rau ultracentrifugation saum 50, 000 rpm.
PE (Polyethylene): Opaque. Nws tsis hnov mob nrog acetone, acetic acid, hydrochloric acid, thiab lwm yam, thiab yog qhov ruaj khov, thiab nws yooj yim los ua mos ntawm qhov kub thiab txias.
PA (Polyamide): Cov khoom siv no yog cov polymer ntawm PP thiab PE, translucent, chemically ruaj khov, tab sis tsis tiv taus qhov kub thiab txias.
PS (polystyrene): pob tshab, siab hardness, ruaj khov rau feem ntau aqueous daws, tab sis yuav corroded los ntawm ntau yam organic tshuaj, feem ntau yog siv rau qis-ceev centrifugation, thiab feem ntau siv ib zaug.
PF (polyfluorine): translucent, tuaj yeem siv rau qhov kub thiab txias, yog tias nws yog qhov chaw sim ntawm -100 degree -140 degree, centrifuge raj ntawm cov khoom siv no tuaj yeem siv.
CAB (Cellulose Acetate Butyl): Pob tshab, tuaj yeem siv rau kev txiav txim siab gradient ntawm dilute acids, alkalis, ntsev, nrog rau cawv thiab sucrose.
Qhov zoo ntawm cov yas centrifuge raj yog tias lawv yog pob tshab lossis translucent, tsis tshua muaj zog, thiab tuaj yeem siv los tshem tawm cov gradients los ntawm kev sib tsoo. Qhov tsis zoo yog tias nws yooj yim rau deform, tsis zoo corrosion kuj rau cov kuab tshuaj organic, thiab muaj lub neej ua haujlwm luv luv. Lub raj yas centrifuge tuaj yeem nruab nrog lub hau npog, uas yog siv los tiv thaiv cov xau ntawm cov qauv, tshwj xeeb tshaj yog thaum nws siv rau cov qauv siv hluav taws xob lossis cov qauv corrosive heev. Nws yog ib qho tseem ceeb heev los tiv thaiv cov xau ntawm cov qauv; Evaporate thiab txhawb lub centrifuge raj kom tsis txhob deformation ntawm lub centrifuge raj. Thaum xaiv cov ntsiab lus no, koj yuav tsum tau ua tib zoo saib xyuas seb lub hau npog lub raj puas nruj, thiab seb nws puas tuaj yeem raug kaw nruj nreem thaum lub sijhawm kuaj, thiaj li ua kom tsis muaj qhov xau thaum thim rov qab.
Qhov zoo ntawm BKMAM centrifuge raj:
Clear Kawm tiav
PP tube, PE cap
Sterile, Dnase & Rnase dawb thiab tsis muaj pyrogen
Ua kom tiav cov kev qhia tshwj xeeb kom tau raws li qhov xav tau ntawm kev sim sib txawv
