Kungakanani okwaziyo mayelana nokuhlukaniswa nokukhethwa kwezinto ezibonakalayo zamashubhu e-centrifuge?

Amashubhu e-Centrifuge:asetshenziselwa ukuqukatha uketshezi phakathi ne-centrifugation, ehlukanisa isampula ezingxenyeni zayo ngokuyizungezisa ngokushesha ku-eksisi egxilile.Itholakala nge-sealing cap noma indlala.Kuyinto yokuhlola evamile ukusetshenziswa elabhorethri.

1. Ngokobukhulu bayo

Ishubhu elikhulu le-centrifuge (500ml, 250ml, Ishubhu elijwayelekile le-centrifuge (50ml, 15ml), ishubhu le-Micro-centrifuge (2ml, 1.5ml, 0.65ml, 0.2ml)

2. Ngokuvumelana nokuma kwephansi

Ishubhu le-centrifuge eliphansi eliphansi, ishubhu le-centrifuge eliphansi eliphansi, ishubhu eliyindilinga eliphansi eliyi-centrifuge

3. Ngokwendlela isivalo esivalwe ngayo

I-Gland centrifuge tube: ishubhu le-centrifuge elivaleka ngomshini wokunyathelisa, elivame ukutholakala kumashubhu amancane.

Ishubhu le-screw cap centrifuge: faka amakepisi ayisicaba (ingaphezulu kwekepisi liyisicaba) namakepisi wepulaki (ngaphezulu kwekepisi linomumo wepulaki)

4. Ngokusho kwempahla: ishubhu lepulasitiki le-centrifuge, ishubhu yengilazi ye-centrifuge, ishubhu yensimbi ye-centrifuge

I-1) Ishubhu ye-Steel centrifuge: Ishubhu yensimbi ye-centrifuge inamandla amakhulu, akukho deformation, ukumelana nokushisa, ukumelana nesithwathwa kanye nokumelana nokugqwala kwamakhemikhali.Ibuye isetshenziswe kabanzi, kodwa futhi kufanele igweme ukuthintana namakhemikhali anamandla alimazayo, njenge-asidi eqinile kanye ne-alkali eqinile.Zama ukugwema ukugqwala kwala makhemikhali

2) Ishubhu ye-Glass centrifuge: Uma usebenzisa amashubhu engilazi, amandla we-centrifugal akufanele abe mkhulu kakhulu, futhi amaphedi enjoloba ayadingeka ukuvimbela amashubhu ukuthi angaphuli.Ngokuvamile, amashubhu engilazi awasetshenziswa kuma-centrifuges anesivinini esikhulu.I-cap ye-centrifuge tube ayivaliwe ngokwanele, futhi uketshezi alukwazi ukugcwaliswa (ngoba ama-centrifuges anesivinini esikhulu kanye nama-angle rotors asetshenziswa) ukuvimbela ukuchichima nokulahlekelwa ibhalansi.Umphumela wokuchitheka ukungcolisa i-rotor ne-centrifugal chamber, okuthinta ukusebenza okuvamile kwenzwa.Ngesikhathi se-ultracentrifugation, ithubhu ye-centrifuge kufanele igcwaliswe ngoketshezi, ngoba i-ultracentrifugation idinga i-vacuum ephezulu, futhi ukugcwaliswa kuphela kungavimbela ithubhu ye-centrifuge ekuwohlokeni.

I-3) Ithubhu ye-Plastiki ye-centrifuge: Inzuzo ye-plastic centrifuge tube ukuthi isobala noma i-translucent, ubulukhuni bayo buncane, futhi isampula ingakhishwa ngokubhoboza.Ububi ukuthi kulula ukuwohloka, alikwazi ukumelana nokugqwala kahle kuzincibilikisi zemvelo, futhi inokuphila okufushane kwesevisi.Amashubhu epulasitiki e-centrifuge enziwe nge-PP (polypropylene), i-PC (i-polycarbonate), i-PE (i-polyethylene) nezinye izinto.Ukusebenza kwepayipi le-PP kungcono kakhulu.I-plastic centrifuge tube ibonakala ngale noma i-translucent, futhi i-centrifugation yesampula ingabonakala ngendlela enembile, kodwa kulula ukuyonakalisa futhi inokumelana nokugqwala okungekuhle kuzincibilikisi zemvelo, ngakho-ke impilo yesevisi ifushane.

Okulandelayo isingeniso esifushane sendaba ngayinye:

I-PP(i-polypropylene): iyashintshashintsha, inamakhemikhali nezinga lokushisa elihle elizinzile, kodwa izoba brittle lapho izinga lokushisa liphansi, ngakho-ke ungafaki i-centrifuge ngaphansi kuka-4°C.

I-PC (i-polycarbonate): ukukhanya okuhle, ubulukhuni obuphezulu, ingafakwa inzalo ekushiseni okuphezulu, kodwa ingamelani ne-asidi eqinile ne-alkali nezinye izincibilikisi eziphilayo ezifana notshwala.Isetshenziselwa ikakhulukazi i-ultra-high-speed centrifugation ngaphezu kuka-50,000 rpm.

I-PE (i-polyethylene): i-opaque.Ayisabeli nge-acetone, i-acetic acid, i-hydrochloric acid, njll. Ayizinzile futhi ijwayele ukuthamba emazingeni okushisa aphezulu.

I-PA (i-polyamide): Le nto i-polymer eyenziwe nge-PP ne-PE, i-translucent, izinzile kakhulu kumakhemikhali amakhemikhali, kodwa ayimelani nokushisa okuphezulu.

I-PS (i-polystyrene): esobala, eqinile, ezinzile ezixazululweni eziningi ezinamanzi amaningi, kodwa izogqwala yizinto ezihlukahlukene eziphilayo, ezisetshenziselwa kakhulu i-centrifugation enesivinini esiphansi, futhi ngokuvamile isetshenziselwa ukusetshenziswa kanye.

PF (i-polyfluorine): i-translucent, ingasetshenziswa ekushiseni okuphansi, uma indawo yokuhlola ingu -100 ℃ -140 ℃, ungasebenzisa ishubhu le-centrifuge elenziwe ngale nto.

I-CAB (Cellulose Butyl Acetate): esobala, ingasetshenziselwa ukunqunywa kwe-gradient ye-dilute acid, ama-alkali, usawoti, utshwala, kanye ne-sucrose.
