3. Bisa ga hanyar da aka rufe murfin
Gland centrifuge tube: centrifuge tube wanda ke rufe da latsa, wanda aka fi samu a cikin bututun microcentrifuge
Screw cap centrifuge tube: hada da lebur iyakoki (saman hula lebur ne) da filogi (saman hula yana da siffar filogi)
4. Bisa ga kayan: filastik centrifuge tube, gilashin centrifuge tube, karfe centrifuge tube
1) Karfe centrifuge tube: The karfe centrifuge tube yana da babban ƙarfi, babu nakasawa, zafi juriya, sanyi juriya da kuma sinadaran juriya.Hakanan ana amfani da shi sosai, amma kuma yakamata a guji haɗuwa da sinadarai masu ƙarfi, kamar acid mai ƙarfi da alkali mai ƙarfi.Yi ƙoƙarin guje wa lalatawar waɗannan sinadarai
2) Bututun Gilashin Gilashi: Lokacin amfani da bututun gilashi, ƙarfin centrifugal bai kamata ya zama babba ba, kuma ana buƙatar fakitin roba don hana bututun daga karyewa.Gabaɗaya, ba a amfani da bututun gilasai a cikin centrifuges masu sauri.Ba a rufe hular bututun centrifuge sosai, kuma ba za a iya cika ruwa ba (don ana amfani da centrifuges mai sauri da rotors na kusurwa) don hana ambaliya da asarar ma'auni.Sakamakon zubewa shine ya gurɓata rotor da ɗakin centrifugal, yana shafar aikin firikwensin na yau da kullun.A lokacin ultracentrifugation, dole ne a cika bututun centrifuge da ruwa, saboda ultracentrifugation yana buƙatar babban injin, kuma cikawa kawai zai iya hana bututun centrifuge daga lalacewa.
3) Bututun centrifuge na filastik: Amfanin bututun centrifuge na filastik shine cewa yana da haske ko kuma mai haske, taurinsa kadan ne, ana iya fitar da samfurin ta hanyar huda.Rashin hasara shi ne cewa yana da sauƙin gurɓatawa, yana da ƙarancin juriya na lalata, kuma yana da ɗan gajeren rayuwar sabis.Ana yin bututun centrifuge na filastik da PP (polypropylene), PC (polycarbonate), PE (polyethylene) da sauran kayan.Ayyukan bututun PP ya fi kyau.Filastik centrifuge tube ne m ko m, kuma centrifugation na samfurin za a iya gani da hankali, amma yana da in mun gwada da sauki nakasawa kuma yana da matalauta lalata juriya ga kwayoyin kaushi, don haka da sabis rayuwa gajere.
Mai zuwa shine taƙaitaccen gabatarwa ga kowane abu:
PP (polypropylene): translucent, tare da kyawawan sinadarai da kwanciyar hankali, amma zai zama gaggautsa a ƙananan zafin jiki, don haka kada ku kasance ƙasa da 4 ° C.
PC (polycarbonate): mai kyau nuna gaskiya, high taurin, za a iya haifuwa a high zafin jiki, amma ba resistant zuwa karfi acid da alkali da wasu kwayoyin kaushi kamar barasa.Ana amfani da shi musamman don matsananci-high-gudun centrifugation sama da 50,000 rpm.
PE (polyethylene): opaque.Ba ya amsa da acetone, acetic acid, hydrochloric acid, da dai sauransu. Yana da ingantacciyar barga kuma yana ƙoƙarin yin laushi a yanayin zafi.
PA (polyamide): Wannan abu shine polymer wanda aka yi da PP da PE, mai jujjuyawa, kwanciyar hankali a cikin abubuwan sinadarai, amma ba mai jure yanayin zafi ba.
PS (polystyrene): m, mai wuya, barga zuwa mafi yawan mafita na ruwa, amma za a lalata su da abubuwa daban-daban na kwayoyin halitta, galibi ana amfani da su don rage saurin gudu, kuma gabaɗaya ana amfani da su don amfani na lokaci ɗaya.
PF (polyfluorine): translucent, ana iya amfani dashi a ƙananan zafin jiki, idan yanayin gwaji shine -100 ℃ -140 ℃, zaka iya amfani da bututun centrifuge da aka yi da wannan abu.
CAB (Cellulose Butyl Acetate): m, ana iya amfani dashi don ƙaddarar ƙarancin acid, alkalis, salts, alcohols, da sucrose.
