Centrifuge tubes:yog siv los ntim cov kua dej thaum lub sij hawm centrifugation, uas cais cov qauv mus rau hauv nws cov khoom los ntawm ceev ceev tig nws nyob ib ncig ntawm lub axis ruaj.Nws muaj nyob rau hauv sealing hau los yog caj pas.Nws yog ib qho kev sim uas siv tau hauv chav kuaj.
1. Raws li nws qhov loj me
Loj muaj peev xwm centrifuge raj (500ml, 250ml, Ib txwm centrifuge raj (50ml, 15ml), Micro-centrifuge tube (2ml, 1.5ml, 0.65ml, 0.2ml)
2. Raws li cov duab hauv qab
Conical hauv qab centrifuge raj, tiaj hauv qab centrifuge raj, puag ncig hauv qab centrifuge raj
3. Raws li txoj kev lub hau kaw
Gland centrifuge raj: ib lub raj centrifuge uas kaw nrog lub xovxwm, feem ntau pom nyob rau hauv microcentrifuge raj
Screw cap centrifuge tube: suav nrog cov kaus mom tiaj tus (sab saum toj ntawm lub hau yog tiaj tus) thiab lub hau ntsaws (sab saum toj ntawm lub hau muaj lub hau ntsaws)
4. Raws li cov khoom siv: yas centrifuge raj, iav centrifuge raj, steel centrifuge raj
1) Steel centrifuge tube: Lub steel centrifuge raj muaj lub zog siab, tsis muaj deformation, kub tsis kam, Frost tsis kam thiab tshuaj corrosion kuj.Nws kuj yog siv dav, tab sis nws yuav tsum tsis txhob sib cuag nrog cov tshuaj muaj zog corrosive, xws li muaj zog acid thiab muaj zog alkali.Sim kom tsis txhob muaj kev xeb ntawm cov tshuaj no
2) Iav centrifuge raj: Thaum siv cov iav raj, lub centrifugal quab yuam yuav tsum tsis txhob loj dhau, thiab cov ntaub qhwv roj hmab yuav tsum tau tiv thaiv cov hlab los ntawm kev tawg.Feem ntau, cov iav raj tsis siv nyob rau hauv high-speed centrifuges.Lub hau ntawm lub centrifuge raj tsis raug kaw txaus, thiab cov kua tsis tuaj yeem sau tau (rau kev siv cov centrifuges siab thiab lub kaum sab xis rotors) los tiv thaiv kev sib tsoo thiab kev sib npaug.Qhov tshwm sim ntawm kev nchuav yog ua paug rau lub rotor thiab lub centrifugal chamber, cuam tshuam rau kev ua haujlwm ntawm lub sensor.Thaum lub sij hawm ultracentrifugation, lub raj centrifuge yuav tsum tau ntim cov kua, vim tias ultracentrifugation yuav tsum muaj lub tshuab nqus tsev siab, thiab tsuas yog txhaws tuaj yeem tiv thaiv lub raj centrifuge los ntawm deforming.
3) Yas centrifuge raj: qhov zoo ntawm cov yas centrifuge raj yog tias nws yog pob tshab los yog translucent, nws hardness yog me me, thiab cov qauv yuav raug muab tshem tawm los ntawm puncture.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.Yas centrifuge raj yog ua los ntawm PP (polypropylene), PC (polycarbonate), PE (polyethylene) thiab lwm yam ntaub ntawv.PP yeeb nkab kev ua tau zoo kuj zoo dua.Cov yas centrifuge raj yog pob tshab los yog translucent, thiab cov centrifugation ntawm cov qauv tuaj yeem pom intuitively, tab sis nws yog ib qho yooj yim rau deform thiab tsis zoo corrosion kuj rau cov kuab tshuaj organic, yog li lub neej kev pab cuam luv luv.
Cov hauv qab no yog cov lus qhia luv luv rau txhua yam khoom:
PP (polypropylene): translucent, nrog cov tshuaj zoo thiab qhov kub thiab txias, tab sis nws yuav ua rau qhov kub thiab txias, yog li tsis txhob centrifuge hauv qab 4 ° C.
PC (polycarbonate): zoo pob tshab, siab hardness, 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.Nws yog tsuas yog siv rau ultra-high-speed centrifugation saum 50,000 rpm.
PE (polyethylene): opaque.Nws tsis hnov mob nrog acetone, acetic acid, hydrochloric acid, thiab lwm yam. Nws yog qhov ruaj khov thiab zoo li mos ntawm qhov kub thiab txias.
PA (polyamide): Cov khoom siv no yog cov khoom siv polymer ua los ntawm PP thiab PE, translucent, ruaj khov hauv tshuaj lom neeg, tab sis tsis tiv taus kub.
PS (polystyrene): pob tshab, nyuaj, ruaj khov rau feem ntau cov kev daws teeb meem aqueous, tab sis yuav corroded los ntawm ntau yam organic tshuaj, feem ntau yog siv rau qis-ceev centrifugation, thiab feem ntau siv rau ib zaug siv.
PF (polyfluorine): translucent, tuaj yeem siv rau qhov kub thiab txias, yog tias qhov chaw sim yog -100 ℃ -140 ℃, koj tuaj yeem siv lub centrifuge raj ua los ntawm cov khoom siv no.
CAB (Cellulose Butyl Acetate): pob tshab, tuaj yeem siv rau kev txiav txim siab gradient ntawm dilute acids, alkalis, ntsev, cawv, thiab sucrose.
