Centrifuge tubes:anoshandiswa kuve nezvinwiwa panguva yecentrifugation, iyo inoparadzanisa sampu muzvikamu zvayo nekukasira kuitenderedza ichitenderedza axis yakagadziriswa.Inowanikwa nevhavha yekuvharisa kana gland.Icho chinhu chinozivikanwa chekuedza chinodyiwa murabhoritari.
1. Maererano nekukura kwayo
Huru inokwana centrifuge chubhu (500ml, 250ml, Normal centrifuge chubhu (50ml, 15ml), Micro-centrifuge chubhu (2ml, 1.5ml, 0.65ml, 0.2ml)
2. Maererano nechimiro chepasi
Conical pazasi centrifuge chubhu, flat pazasi centrifuge chubhu, kutenderera kuzasi centrifuge chubhu
3. Maererano nenzira iyo chivharo chakavharwa
Gland centrifuge chubhu: centrifuge chubhu inonamira nemuchina, inowanzowanikwa mune microcentrifuge chubhu.
Screw cap centrifuge chubhu: sanganisira zvivharo zvakapfava (pamusoro pekepisi yakati sandara) uye mavhavha evhavha (kumusoro kwekapu kune chimiro cheplug)
4. Maererano nezvinhu: plastiki centrifuge chubhu, girazi centrifuge chubhu, simbi centrifuge chubhu.
1) Simbi centrifuge chubhu: Simbi centrifuge chubhu ine simba rakawanda, hapana deformation, kupisa kupisa, chando kuramba uye kemikari corrosion kuramba.Inoshandiswawo zvakanyanya, asi inofanirawo kudzivisa kusangana nemakemikari ane simba anoparadza, akadai seasidhi yakasimba uye alkali yakasimba.Edza kudzivisa kuora kwemakemikari aya
2) Girazi centrifuge chubhu: Paunenge uchishandisa machubhu egirazi, simba recentrifugal harifanire kunge rakakura, uye mapedhi erabha anodiwa kudzivirira machubhu kuti asatyoke.Kazhinji, machubhu egirazi haashandiswe mu-high-speed centrifuges.Chivharo che centrifuge chubhu haina kuvharwa zvakakwana, uye mvura haigoni kuzadzwa (nokuda kwe-high-speed centrifuges uye angle rotors inoshandiswa) kudzivirira kudarika uye kurasikirwa kwekuenzanisa.Mhedzisiro yekuyerera ndeyekusvibisa rotor uye centrifugal chamber, inokanganisa kushanda kwakajairika kwe sensor.Munguva ye ultracentrifugation, iyo centrifuge chubhu inofanirwa kuzadzwa nemvura, nekuti ultracentrifugation inoda yakakwira vacuum, uye kuzadza chete kunogona kudzivirira iyo centrifuge chubhu kubva pakukanganisa.
3) Plastiki centrifuge chubhu: Kubatsira kwepurasitiki centrifuge chubhu ndeyokuti inopenya kana kuti inopenya, kuoma kwayo kuduku, uye muenzaniso unogona kutorwa kunze nekuputira.Chakashata ndechekuti iri nyore kutsveyamisa, ine kushomeka kwekushomeka kune organic zvinonyungudutsa, uye ine hupenyu hupfupi hwesevhisi.Plastic centrifuge tubes yakagadzirwa nePP (polypropylene), PC (polycarbonate), PE (polyethylene) nezvimwe zvinhu.PP pombi kuita kuri nani.Iyo plastiki centrifuge chubhu inopenya kana kupenya, uye centrifugation yemuenzaniso inogona kuoneka intuitively, asi iri nyore kukanganisa uye ine urombo husina kunaka hwekuramba kune organic zvinonyungudutsa, saka hupenyu hwesevhisi hupfupi.
Inotevera sumo pfupi yechinhu chimwe nechimwe:
PP (polypropylene): inopenya, ine kemikari yakanaka uye kugadzikana kwetembiricha, asi ichaita brittle pakudziya kwakaderera, saka usaite centrifuge iri pasi pe4°C.
PC (polycarbonate): kujeka kwakanaka, kuomarara kwepamusoro, kunogona kuomeswa patembiricha yakakwira, asi isingamirire kune yakasimba asidhi uye alkali uye zvimwe organic zvinonyungudutsa sedoro.Inonyanya kushandiswa kune yekupedzisira-yepamusoro-kumhanya centrifugation pamusoro pe50,000 rpm.
PE (polyethylene): opaque.Izvo hazviiti neacetone, acetic acid, hydrochloric acid, etc. Iyo yakanyatsogadzikana uye inowanzoita kupfava pakupisa kwakanyanya.
PA (polyamide): Nyaya iyi ipolymer yakagadzirwa nePP uye PE, inopenya, yakagadzikana zvakanyanya mumakemikari zvinhu, asi isingamiri kune yakanyanya kupisa.
PS (polystyrene): yakajeka, yakaoma, yakagadzikana kune yakawanda yemvura inogadzirisa, asi ichasvibiswa nezvinhu zvakasiyana-siyana zvehupenyu, kunyanya kushandiswa kwepasi-speed centrifugation, uye inowanzoshandiswa kushandiswa kwenguva imwe chete.
PF (polyfluorine): translucent, inogona kushandiswa pakadzika tembiricha, kana nharaunda yekuyedza iri -100 ℃ -140 ℃, unogona kushandisa centrifuge chubhu yakagadzirwa nechinhu ichi.
CAB (Cellulose Butyl Acetate): yakajeka, inogona kushandiswa kune gradient kutsunga kwe dilute acids, alkalis, munyu, doro, uye sucrose.
