Cov ntsiab lus yuav tsum nco ntsoov hauv kev xaiv ntawm chav kuaj centrifuges

Tig ceev

Domestic desktop centrifuges tau muab faib ua qis-ceev centrifuges (< 10000rpm/min), high-speed centrifuges (> 10000rpm/min, a 30000rpm/min), and ultra-high-speed centrifuges (>) raws li qhov siab tshaj plaws ceev 30, 000 rpm / min), txhua qhov centrifuge muaj qhov ntsuas siab tshaj plaws.

Qhov siab tshaj plaws ceev yog hais txog qhov ceev nyob rau hauv tsis muaj load, tab sis qhov siab tshaj plaws ceev nws txawv nyob ntawm seb hom rotor thiab qhov loj ntawm cov qauv loj. Piv txwv li, qhov ntsuas ceev ntawm lub centrifuge yog 16000rpm / min, uas txhais tau hais tias lub rotor tig 16000 zaug ib feeb thaum nws tsis thauj khoom, thiab tom qab ntxiv cov qauv, qhov ceev yuav twv yuav raug qis dua 16000rpm / min. Cov rotors sib txawv, qhov siab tshaj plaws ceev kuj txawv, lub centrifuge tuaj yeem nruab nrog ntau lub rotors, cov nyhuv centrifuge sib cais feem ntau tsis yog nyob ntawm qhov ceev, tab sis ntawm lub zog centrifugal, yog li qee zaum qhov ceev tsis ua raws li qhov yuav tsum tau ua, ntev li ntev tau. centrifugal quab yuam tuaj yeem ua tau raws li tus qauv yog tib yam, qhov kev sim tuaj yeem ua tiav qhov yuav tsum tau ua.

Kub

Qee cov qauv (xws li cov protein, cov hlwb, thiab lwm yam) yuav raug rhuav tshem nyob rau hauv ib puag ncig kub, uas yuav tsum tau xaiv cov tub yees centrifuges, uas muaj qhov ntsuas kub ntau. Cov cua sov tsim los ntawm cov centrifuge hauv kev ua haujlwm siab ceev thiab lub tub yees ntawm lub centrifuge yog sib npaug ntawm qhov kub thiab txias (feem ntau cov qauv ntawm cov tub yees centrifugation yuav tsum tau khaws cia ntawm 3 degree ~ 8 degree), qhov tshwj xeeb tuaj yeem ncav cuag yog kuj muaj feem xyuam rau lub rotor, xws li ib tug centrifuge ntsuas kub ntau ntawm -20 degree ~ 40 degree, nruab nrog ib tug kab rov tav rotor tuaj yeem ncav cuag li 3 degree thaum tig, yog tias lub kaum sab xis rotor tuaj yeem ncav cuag li 7 degree, qhov xwm txheej tshwj xeeb nyob ntawm qhov ntsuas kub thiab ceev thiab rotor txiav txim siab.

Muaj peev xwm

Muaj pes tsawg tus qauv raj yuav tsum tau centrifuged txhua lub sij hawm, yuav tsum muaj peev xwm npaum li cas rau txhua tus qauv raj, cov yam ntxwv no txiav txim siab tag nrho lub peev xwm ntawm lub centrifuge, yooj yim muab, tag nrho lub peev xwm ntawm lub centrifuge=lub peev xwm ntawm txhua centrifuge raj × tus naj npawb ntawm cov raj centrifuge, tag nrho lub peev xwm thiab qhov loj ntawm cov khoom ua haujlwm tau sib phim.

Rotor

Lub rotor ntawm lub chaw soj nstuam centrifuge feem ntau muab faib ua ob hom, kab rov tav rotor: lub dai xiav thiab lub xeem raj yog nyob rau hauv ib tug kab rov tav lub xeev thaum khiav, ntawm txoj cai kaum rau lub rotating ncej, thiab cov qauv yuav mloog zoo rau nag lossis daus nyob rau hauv qab. ntawm lub centrifuge tube. Lub kaum sab xis rotor: Lub nkoj centrifuge yog nyob rau ntawm lub kaum sab xis rau lub rotating ncej, thiab cov qauv concentrates lub pellet nyob rau hauv qab ntawm lub centrifuge raj thiab nyob rau sab phab ntsa ze rau hauv qab. Xaiv lub rotor kab rov tav yog tias koj xav kom cov qauv sib cais kom muaj zog nyob rau hauv qab ntawm lub raj, thiab lub kaum sab xis rotor yog tias koj xav kom cov qauv ua kom muaj zog rau hauv qab ntawm lub raj thiab ntawm phab ntsa nyob ze rau hauv qab. Kuj tseem muaj cov kev kuaj tshwj xeeb lossis cov qauv tshwj xeeb uas xav tau tshwj xeeb rotors, xws li: lub peev xwm loj dai pob tawb (feem ntau yog siv hauv cov chaw kho ntshav), enzyme phaj rotors, swb rotors, PCR rotors, raj khib rotors thiab capillary rotors. Lub rotor muaj qhov tshwj xeeb ruaj khov, nws tau ua ke nrog lub peev xwm ntawm lub centrifuge, xws li 36 × 5ml lub kaum sab xis rotor, ob qho tib si txiav txim siab hom rotor thiab txiav txim siab lub peev xwm ntawm lub centrifuge, ntxiv rau, cov khoom siv rotor kuj tau muab faib ua engineering plastics. , stainless hlau, aluminium alloy, titanium alloy thiab lwm yam ntaub ntawv, qhov sib txawv ntawm cov khoom xaiv ncaj qha txiav txim siab tus nqi, ceev thiab kev pab cuam lub neej ntawm rotor, yog li kev xaiv ntawm rotor yog ib qho tseem ceeb heev.

Tswj qhov system

Benchtop Laboratory centrifuges tau nruab nrog microcomputer tswj tshuab uas tsis tsuas yog ua kom muaj kev nyab xeeb ntawm cov centrifuge, tab sis kuj automate ua tiav cov haujlwm ua haujlwm. Tam sim no ntau lub centrifuges muaj kev tswj hwm tib neeg zoo dua. Piv txwv li: rotor paub txog kev ua haujlwm, kev ruaj ntseg ntsuas phoo muaj nuj nqi, tsis siv neeg ntsuas kev ua haujlwm, kev ua txhaum sai sai, kev nrawm nrawm thiab qeeb qeeb, thiab lwm yam. Ntxiv rau cov ntsiab lus saum toj no, nws yuav tsum tau them sai sai rau qee cov ntsiab lus thiab cov khoom tsim nyog.

Lub cev muaj zog

Lub ntsiab tseem ceeb ntawm lub centrifuge yog lub cev muaj zog, lub cev muaj zog yog muab faib ua lub cev muaj zog nrog carbon txhuam thiab lub cev muaj zog uas tsis muaj cov txhuam hniav, qhov qub vim yog qhov tsis zoo ntawm cov toner muaj kuab paug, suab nrov, xav tau kev tu thiab hloov cov pa roj carbon txhuam. , thiab lwm yam, tau raug tshem tawm, feem ntau ntawm cov centrifuges yog brushless motors, thiab qee lub motors kuj muaj nres ua haujlwm. Cov tub yees centrifuges kuj sib txawv ntawm cov tub yees, thiab cov cuab yeej zoo ib puag ncig yog cov tub yees tsis muaj fluorine.

Tsis tas li ntawd, nws tseem yuav tsum tau xav txog qhov teeb meem ntawm lub suab nrov, sim xaiv lub centrifuge nrog lub suab nrov tsawg, kom tswj tau qhov chaw sim zoo. Qee qhov chaw centrifuges siv cov raj centrifuge tshwj xeeb (cov centrifuge toxic kuaj los yog cov qauv uas yuav tsum tau ultra-high-speed centrifugation), uas yuav tsum tau nruab nrog cov tes tsho sib txuas kom muaj kev nyab xeeb dua. Kuj tseem muaj cov thawv ntim tshwj xeeb (cov vials tsis tu ncua, cov hnab ntshav, thiab lwm yam), cov ntsiab lus thiab cov khoom siv no yuav tsum tau ua tib zoo txiav txim siab thaum xaiv lub centrifuge, txwv tsis pub ua haujlwm li qub yuav ua tsis tau.
