Cov khoom siv yas siv tau yooj yim hauv chav kuaj
Muaj ntau yam kev sim khoom siv.Ntxiv nrog rau cov iav consumables, feem ntau siv yog cov khoom siv yas.Yog li koj puas paub tias cov khoom siv yas siv hauv lub neej txhua hnub yog dab tsi?Dab tsi yog cov yam ntxwv?Yuav xaiv li cas?Cia peb teb ib los ntawm ib tug raws li hauv qab no.
Cov khoom siv yas siv hauv chav kuaj yog feem ntaucov lus qhia pipette, centrifuge tubes,PCR daim hlau, cell kab lis kev cai tais diav / phaj / fwj, cryovials, thiab lwm yam. Feem ntau ntawm cov lus qhia pipette, PCR daim hlau, cryovials thiab lwm yam consumables siv yog PP.Khoom siv (polypropylene),cell culture consumablesFeem ntau yog ua los ntawm PS (polystyrene), cell culture flasks yog ua los ntawm PC (polycarbonate) los yog PETG (polyethylene terephthalate copolymer).
1. Polystyrene (PS)
Nws muaj lub teeb xa hluav taws xob zoo thiab tsis muaj tshuaj lom, nrog lub teeb xa hluav taws xob ntawm 90%.Nws muaj cov tshuaj tiv thaiv zoo rau cov tshuaj aqueous, tab sis tsis zoo rau cov kuab tshuaj.Nws muaj qee yam nqi zoo piv rau lwm yam yas.High transparency thiab siab hardness.
PS cov khoom yog nkig nyob rau hauv chav tsev kub thiab yog nquag tawg los yog tawg thaum poob.Qhov kub siv tas mus li yog li 60 ° C, thiab qhov siab tshaj plaws siv yuav tsum tsis pub tshaj 80 ° C.Nws tsis tuaj yeem ua kom tsis muaj menyuam los ntawm qhov kub thiab txias ntawm 121 ° C.Koj tuaj yeem xaiv electron beam sterilization lossis tshuaj sterilization.
Shandong Labio lub cell kab lis kev cai fwj, cell kab lis kev cai tais diav, cell kab lis kev cai daim hlau, thiab serological pipettes yog tag nrho cov ua los ntawm polystyrene (PS).
2. Polypropylene (PP)
Cov qauv ntawm polypropylene (PP) zoo ib yam li polyethylene (PE).Nws yog ib qho thermoplastic resin ua los ntawm polymerization ntawm propylene.Nws feem ntau yog cov khoom tsis muaj xim tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom.Nws lub ntsiab kom zoo dua yog tias nws tuaj yeem siv rau qhov kub thiab txias ntawm 121 ° C.Sterilize.
Polypropylene (PP) muaj cov khoom siv zoo thiab tshuaj lom neeg.Nws tuaj yeem tiv taus corrosion ntawm acids, alkalis, kua ntsev thiab ntau yam organic solvents hauv qab 80 ° C.Nws muaj rigidity zoo dua, lub zog thiab kub tsis kam tshaj polyethylene (PE).;Hais txog qhov kub thiab txias, PP kuj tseem siab dua PE.Yog li ntawd, thaum koj xav tau lub teeb kis tau tus mob los yog kev soj ntsuam yooj yim, los yog siab dua kev tiv thaiv los yog kub consumables, koj muaj peev xwm xaiv PP consumables.
3. Polycarbonate (PC)
Nws muaj qhov zoo toughness thiab rigidity, tsis yooj yim tawg, thiab muaj ob qho tib si kub tsis kam thiab hluav taws xob tsis kam.Nws ua tau raws li qhov yuav tsum tau muaj ntawm qhov kub thiab txias siab kom tsis muaj menyuam thiab ua kom muaj zog hluav taws xob ntau hauv biomedical teb.Polycarbonate (PC) feem ntau tuaj yeem pom hauv qee yam khoom siv, xws likhov thawvthiaberlenmeyer khob.
4. Polyethylene (PE)
Ib hom thermoplastic resin, tsis muaj ntxhiab, tsis muaj tshuaj lom, zoo li siv quav ciab, muaj qhov tsis zoo ntawm qhov kub thiab txias (qhov kub tshaj plaws ua haujlwm tuaj yeem ncav cuag -100 ~ -70 ° C), thiab yooj yim softens ntawm qhov kub thiab txias.Nws muaj cov tshuaj lom neeg ruaj khov zoo vim tias cov polymer molecules txuas nrog carbon-carbon ib daim ntawv cog lus thiab tuaj yeem tiv thaiv kev yaig ntawm feem ntau cov kua qaub thiab alkalis (tsis tiv taus cov kua qaub nrog oxidizing zog).
Hauv cov ntsiab lus, polypropylene (PP) thiab polyethylene (PE) yog hom yas ntau tshaj plaws hauv chav kuaj.Thaum xaiv cov khoom siv, feem ntau koj tuaj yeem xaiv ob qho no yog tias tsis muaj kev xav tau tshwj xeeb.Yog tias muaj qhov yuav tsum tau ua kom muaj qhov kub thiab txias thiab kub siab kom tsis muaj menyuam, koj tuaj yeem xaiv cov khoom siv los ntawm polypropylene (PP);Yog tias koj muaj kev xav tau rau kev ua haujlwm kub qis, koj tuaj yeem xaiv polyethylene (PE);thiab rau cell culture consumables Feem ntau ntawm lawv yog ua los ntawm polystyrene (PS).
