Izinto ezisetshenziswayo zepulasitiki ezivamile kuma-laboratories

Kukhona izinto ezisetshenziswayo zokuhlola ezahlukahlukene.Ngaphezu kwezinto ezisetshenziswayo zengilazi, ezisetshenziswa kakhulu yizinto zepulasitiki.Ngakho-ke uyazi ukuthi yiziphi izinto ezisetshenziswa epulasitiki ezisetshenziswa empilweni yansuku zonke ezenziwe ngazo?Yiziphi izici?Indlela yokukhetha?Ake siphendule ngamunye ngamunye njengoba ngezansi.

Izinto ezisetshenziswa epulasitiki ezisetshenziswa elabhorethri ikakhulukaziamathiphu we-pipetteamashubhu centrifuge,Amapuleti e-PCR, izitsha ze-cell culture / amapuleti / amabhodlela, ama-cryovials, njll. Iningi lamathiphu e-pipette, amapuleti e-PCR, ama-cryovials nezinye izinto ezisetshenziswayo ezisetshenziswayo yi-PP.Izinto ezibonakalayo (i-polypropylene),izinto ezidlekayo zesiko lamaselingokuvamile enziwe nge-PS (i-polystyrene), amaflaski e-cell culture enziwe nge-PC (polycarbonate) noma i-PETG (i-polyethylene terephthalate copolymer).

1. I-Polystyrene (PS)

Inokudlulisa kahle ukukhanya futhi ayinabo ubuthi, inokudlulisa ukukhanya okungama-90%.Inokumelana okuhle kwamakhemikhali ezixazululweni ezinamanzi, kodwa imelana kabi nezincibilikisi.Inezinzuzo ezithile zezindleko uma kuqhathaniswa namanye amapulasitiki.Ukucaca okuphezulu nobulukhuni obuphezulu.

Imikhiqizo ye-PS ilukhuni uma kuqhathaniswa nezinga lokushisa legumbi futhi ijwayele ukuqhekeka noma ukuphuka lapho yehliswa.Izinga lokushisa eliqhubekayo lokusebenzisa licishe libe ngu-60°C, kanti izinga lokushisa eliphezulu lokusetshenziswa akufanele lidlule ku-80°C.Angeke ifakwe inzalo ngokushisa okuphezulu kanye nomfutho ophezulu ongu-121°C.Ungakhetha inzalo ye-electron beam noma inzalo yamakhemikhali.

Amabhodlela e-Shandong Labio's cell culture, izitsha ze-cell culture, amapuleti e-cell culture, nama-serological pipette konke enziwe nge-polystyrene (PS).

2. I-Polypropylene (PP)

Isakhiwo se-polypropylene (PP) sifana ne-polyethylene (PE).I-resin ye-thermoplastic eyenziwe nge-polymerization ye-propylene.Ivamise ukuba yi-translucent engenambala eqinile, engenaphunga futhi engenabuthi.Inzuzo yayo enkulu ukuthi ingasetshenziswa emazingeni okushisa aphezulu kanye nokucindezela kwe-121 ° C.Nciphisa.

I-Polypropylene (PP) inezici ezinhle zemishini kanye nokumelana namakhemikhali.Ingakwazi ukumelana nokugqwala kwama-asidi, ama-alkali, uketshezi lukasawoti nezinyibilikisi ezihlukahlukene eziphilayo ezingaphansi kuka-80°C.Inokuqina okungcono, amandla nokumelana nokushisa kune-polyethylene (PE).;Mayelana nokumelana nokushisa, i-PP nayo iphakeme kune-PE.Ngakho-ke, uma udinga ukudluliswa kokukhanya noma ukubhekwa kalula, noma ukumelana nokucindezela okuphezulu noma okudlekayo kwezinga lokushisa, ungakhetha okusebenzisekayo kwe-PP.

3. I-Polycarbonate (PC)

Inokuqina okuhle nokuqina, ayinqamuki kalula, futhi inokubili ukumelana nokushisa kanye nokumelana nemisebe.Ihlangabezana nezidingo zokuvala izinga lokushisa eliphezulu kanye nokucindezela okuphezulu nokucubungula ngemisebe enamandla emkhakheni we-biomedical.I-Polycarbonate (PC) ingabonakala kaningi kwezinye izinto ezisetshenziswayo, njengeamabhokisi okuqandisafuthiama-flask e-erlenmeyer.

4. I-polyethylene (PE)

Uhlobo lwenhlaka ye-thermoplastic, engenaphunga, engenabuthi, izwakala njengengcina, inokumelana okuhle kakhulu nezinga lokushisa eliphansi (izinga lokushisa eliphansi kakhulu lokusebenza lingafinyelela -100~-70 ° C), futhi lithambisa kalula emazingeni okushisa aphezulu.Inokuqina okuhle kwamakhemikhali ngoba ama-molecule e-polymer axhunywe ngebhondi eyodwa ye-carbon-carbon futhi angakwazi ukumelana nokuguguleka kwama-acids amaningi nama-alkali (awakwazi ukumelana nama-asidi anezakhiwo zokuxilisa).

Kafushane, i-polypropylene (PP) ne-polyethylene (PE) yizinhlobo ezivame kakhulu zamapulasitiki kumalabhorethri.Lapho ukhetha okusebenzisekayo, ngokuvamile ungakhetha lezi ezimbili uma zingekho izidingo ezikhethekile.Uma kunezidingo zokumelana nokushisa okuphezulu kanye nokushisa okuphezulu kanye nokuvala inzalo yokucindezela okukhulu, ungakhetha izinto ezisetshenziswayo ezenziwe nge-polypropylene (PP);uma unezidingo zokusebenza kokushisa okuphansi, ungakhetha i-polyethylene (PE);kanye nezinto ezisetshenziswayo ze-cell culture Iningi lazo lenziwe nge-polystyrene (PS).
