Machubu a Centrifuge:amagwiritsidwa ntchito kukhala ndi zamadzimadzi panthawi ya centrifugation, yomwe imalekanitsa chitsanzocho kukhala zigawo zake pozungulira mofulumira mozungulira mozungulira.Imapezeka ndi kapu yosindikiza kapena gland.Ndiwoyesera wamba wogwiritsidwa ntchito mu labotale.
1. Molingana ndi kukula kwake
Chubu chachikulu cha centrifuge (500ml, 250ml, chubu chodziwika bwino cha centrifuge (50ml, 15ml), chubu la Micro-centrifuge (2ml, 1.5ml, 0.65ml, 0.2ml)
2. Malinga ndi mawonekedwe a pansi
chubu chapansi cha centrifuge, chubu chapansi cha centrifuge, chubu chozungulira chapansi cha centrifuge
3. Malingana ndi momwe chivindikirocho chimatsekedwa
Gland centrifuge chubu: chubu cha centrifuge chomwe chimamata ndi makina osindikizira, omwe amapezeka m'machubu a microcentrifuge
Screw cap centrifuge chubu: phatikizani zipewa zathyathyathya (pamwamba pa chipewa ndi chathyathyathya) ndi zipewa zamapulagi (pamwamba pa kapu pali mawonekedwe apulagi)
4. Malinga ndi zinthu: pulasitiki centrifuge chubu, galasi centrifuge chubu, zitsulo centrifuge chubu
1) Chubu chachitsulo cha centrifuge: chubu chachitsulo cha centrifuge chili ndi mphamvu zambiri, palibe mapindikidwe, kukana kutentha, kukana chisanu ndi kukana kwa dzimbiri.Amagwiritsidwanso ntchito kwambiri, koma ayeneranso kupewa kukhudzana ndi mankhwala amphamvu owononga, monga asidi amphamvu ndi alkali wamphamvu.Yesetsani kupewa dzimbiri za mankhwalawa
2) Galasi centrifuge chubu: Mukamagwiritsa ntchito machubu agalasi, mphamvu ya centrifugal siyenera kukhala yayikulu kwambiri, ndipo pakufunika mphira kuti machubu asathyoke.Nthawi zambiri, machubu agalasi sagwiritsidwa ntchito pama centrifuges othamanga kwambiri.Chophimba cha chubu cha centrifuge sichimatsekedwa mokwanira, ndipo madziwo sangathe kudzazidwa (chifukwa ma centrifuges othamanga kwambiri ndi ma angle rotors amagwiritsidwa ntchito) kuteteza kusefukira ndi kutayika bwino.Zotsatira za kutayika ndikuipitsa rotor ndi chipinda cha centrifugal, zomwe zimakhudza ntchito yachibadwa ya sensa.Panthawi ya ultracentrifugation, chubu cha centrifuge chiyenera kudzazidwa ndi madzi, chifukwa ultracentrifugation imafuna vacuum yapamwamba, ndipo kudzaza kokha kungalepheretse chubu cha centrifuge kuti chisawonongeke.
3) Pulasitiki ya centrifuge chubu: Ubwino wa chubu la pulasitiki la centrifuge ndikuti ndi lowonekera kapena losasunthika, kuuma kwake ndi kochepa, ndipo chitsanzocho chikhoza kutengedwa ndi puncture.Choyipa chake ndikuti ndi chosavuta kupunduka, sichikhala ndi dzimbiri chosakanizidwa ndi zosungunulira za organic, ndipo chimakhala ndi moyo waufupi wautumiki.Machubu apulasitiki a centrifuge amapangidwa ndi PP (polypropylene), PC (polycarbonate), PE (polyethylene) ndi zida zina.Kuchita kwa chitoliro cha PP ndikwabwinoko.Pulasitiki centrifuge chubu ndi mandala kapena translucent, ndi centrifugation chitsanzo akhoza kuoneka mwachidziwitso, koma ndi yosavuta kupunduka ndipo ali osauka dzimbiri kukana zosungunulira organic, kotero moyo utumiki ndi waufupi.
Nawa mawu oyamba achidule a nkhani iliyonse:
PP (polypropylene): yowoneka bwino, yokhala ndi mankhwala abwino komanso kukhazikika kwa kutentha, koma imakhala yolimba pakatentha pang'ono, choncho musalole kuti centrifuge ikhale pansi pa 4 ° C.
PC (polycarbonate): kuwonekera bwino, kuuma kwakukulu, kumatha kusamalidwa pa kutentha kwakukulu, koma osagonjetsedwa ndi asidi amphamvu ndi alkali ndi zosungunulira zina monga mowa.Amagwiritsidwa ntchito kwambiri popangira ma centrifugation othamanga kwambiri kuposa 50,000 rpm.
PE (polyethylene): opaque.Sachita ndi acetone, acetic acid, hydrochloric acid, ndi zina zotero. Zimakhala zokhazikika ndipo zimakhala zofewa pa kutentha kwakukulu.
PA (polyamide): Nkhaniyi ndi polima yopangidwa ndi PP ndi PE, yosasunthika, yosasunthika pamapangidwe amankhwala, koma osagonjetsedwa ndi kutentha kwakukulu.
PS (polystyrene): yowonekera, yolimba, yosasunthika ku njira zambiri zamadzimadzi, koma idzawonongeka ndi zinthu zosiyanasiyana zamoyo, zomwe zimagwiritsidwa ntchito popanga centrifugation yotsika kwambiri, ndipo zimagwiritsidwa ntchito nthawi imodzi.
PF (polyfluorine): translucent, angagwiritsidwe ntchito pa kutentha otsika, ngati chilengedwe experimental -100 ℃ -140 ℃, mungagwiritse ntchito chubu centrifuge zopangidwa nkhaniyi.
CAB (Cellulose Butyl Acetate): yowonekera, imatha kugwiritsidwa ntchito pozindikira kuchepetsedwa kwa ma acid, alkali, mchere, mowa, ndi sucrose.
