Nnukwu ikike centrifuge tube (500ml, 250ml, Nkịtị centrifuge tube (50ml, 15ml), Micro-centrifuge tube (2ml, 1.5ml, 0.65ml, 0.2ml)
2. Dị ka ọdịdị nke ala
Conical ala centrifuge tube, ewepụghị ala centrifuge tube, gburugburu ala centrifuge tube
3. Dị ka ụzọ e si emechi mkpuchi
Gland centrifuge tube: tube centrifuge nke na-eji igwe nbipute mechie, nke a na-ahụkarị na tubes microcentrifuge
Screw okpu centrifuge tube: gụnyere okpu dị larịị (elu okpu ahụ dị larịị) na mkpuchi plọg (elu okpu nwere udi plọg)
4. Dị ka ihe onwunwe: plastic centrifuge tube, iko centrifuge tube, ígwè centrifuge tube.
1) Steel centrifuge tube: The ígwè centrifuge tube nwere nnukwu ike, ọ dịghị nrụrụ, okpomọkụ na-eguzogide, ntu oyi na-eguzogide na chemical corrosion iguzogide.A na-ejikwa ya eme ihe n'ọtụtụ ebe, mana o kwesịkwara izere kọntaktị na kemịkalụ siri ike na-emebi emebi, dị ka acid siri ike na alkali siri ike.Gbalịa ka ị zere mmebi nke kemịkalụ ndị a
2) Glass centrifuge tube: Mgbe ị na-eji tubes iko, ike centrifugal ekwesịghị ịdị oke, na ihe mkpuchi rọba dị mkpa iji gbochie tubes ka ọ ghara imebi.N'ozuzu, a naghị eji tubes iko mee ihe na centrifuges dị elu.A naghị emechi okpu nke tube centrifuge nke ọma, a pụghị imejupụta mmiri mmiri (maka centrifuges dị elu na rotors angle) iji gbochie oke mmiri na nkwụsị nke nguzozi.Nsonaazụ nke mkpofu bụ imerụ rotor na ụlọ centrifugal, na-emetụta ọrụ nkịtị nke ihe mmetụta.N'oge ultracentrifugation, tube centrifuge ga-ejupụta na mmiri mmiri, n'ihi na ultracentrifugation chọrọ oghere dị elu, naanị ndochi nwere ike igbochi tube centrifuge ka ọ ghara imebi.
3) Plastic centrifuge tube: Uru nke plastic centrifuge tube bụ na ọ na-apụta ìhè ma ọ bụ translucent, ike ya dị ntakịrị, enwere ike wepụ ihe nlele ahụ site na nsị.Ọdịmma ya bụ na ọ dị mfe nrụrụ, na-adịghị mma corrosion eguzogide organic solvents, na nwere obere ọrụ ndụ.A na-eme tubes centrifuge plastik nke PP (polypropylene), PC (polycarbonate), PE (polyethylene) na ihe ndị ọzọ.Ịrụ ọrụ ọkpọkọ PP ka mma.The plastic centrifuge tube bụ transperent ma ọ bụ translucent, na centrifugation nke sample nwere ike ịhụ n'uche, ma ọ dịtụ mfe deform na nwere ogbenye corrosion iguzogide organic solvents, ya mere ndụ ọrụ dị mkpụmkpụ.
Nke a bụ okwu mmalite dị nkenke nke ihe ọ bụla:
PP (polypropylene): translucent, nke nwere kemịkalụ dị mma na nkwụsi ike, mana ọ ga-abụ nke na-akụkụ na obere okpomọkụ, yabụ etinyela centrifuge n'okpuru 4 Celsius.
PC (polycarbonate): nghọta dị mma, isi ike dị elu, enwere ike ịgba ọgwụ mgbochi na oke okpomọkụ, mana ọ naghị eguzogide acid siri ike na alkali na ụfọdụ ihe mgbaze organic dị ka mmanya.A na-ejikarị ya maka centrifugation ultra-high-speed n'elu 50,000 rpm.
PE (polyethylene): opaque.Ọ naghị emeghachi omume na acetone, acetic acid, hydrochloric acid, wdg. Ọ dịtụ kwụsiri ike ma na-eme ka ọ dị nro na oke okpomọkụ.
PA (polyamide): Ihe a bụ polymer nke PP na PE mere, translucent, kwụsiri ike na akụrụngwa kemịkal, mana ọ naghị eguzogide oke okpomọkụ.
PS (polystyrene): transperent, siri ike, kwụsiri ike ruo ọtụtụ mmiri mmiri, mana a ga-emebi ya site na ihe dị iche iche organic, nke a na-ejikarị maka centrifugation dị ala, na-ejikarị eme ihe maka otu oge.
PF (polyfluorine): translucent, enwere ike iji ya na obere okpomọkụ, ma ọ bụrụ na ebe nnwale bụ -100 ℃ -140 ℃, ị nwere ike iji tube centrifuge mere nke ihe a.
CAB (Cellulose Butyl Acetate): transperent, enwere ike iji ya mee mkpebi nke gradient nke acid dilute, alkalis, salts, alcohols, na sucrose.
