Kuaj cov khoom siv ntau hom ntawm hom, thiab tsis muaj ib qho khoom siv tau ua tau raws li txhua yam kev sim. Yog li, koj puas paub cov ntaub ntawv twg yog siv rau hauv cov khoom siv yas? Thiab dab tsi yog qhov sib txawv hauv lawv lub cev thiab tshuaj lom neeg? Tam sim no peb tab tom teb cov lus nug no ib los ntawm ib qho hauv qab no.

Pp (polypropylene)

Polypropylene, abbriabe raws li PP, yog cov polymer tsim los ntawm qhov sib ntxiv polymerization ntawm propylene. Feem ntau nws yog cov translucent, tsis muaj kob, tsw, thiab tsis muaj tshuaj lom. Nws muaj qhov kub thiab txias ruaj khov thiab tuaj yeem yauv ua kom tsis muaj menyuam thaum muaj kub thiab kub thiab ua kom ntev ntawm 121 ° C. Txawm li cas los xij, nws dhau los ua cov nkig ntawm tsawg kub (qis dua 4 ° C) thiab muaj feem ntau mus tawg lossis tawg thaum nqis los ntawm qhov siab.

Polypropylene (PP) Cov khoom pov thawj ua pov thawj zoo heev cov khoom siv kho mob thiab tshuaj lom neeg kuj. Nws tuaj yeem tiv taus corrosion los ntawm cov kua qaub, hauv paus, cov ntsev, thiab ntau yam organic cov kuab tshuaj nyob hauv qab 80 ° C. Piv rau polyethylene (PE), pp muab zoo dua me ntsis, lub zog, thiab lub cua sov kuj. Yog li ntawd, thaum cov neeg muaj kev tiv thaiv lub teeb lossis kev soj ntsuam yooj yim, ntxiv rau lub zog compressive ntau lossis cov khoom siv kub, pp tuaj yeem xaiv tau.

Consumables xws li cov leeg centrifuge, pCr cov paib, reagent fwj, cia yas yog txhua qhov ua los ntawm polypropylene raws li cov khoom siv raw.

PS (polystyrene)

Polystyrene (PS), synthesized los ntawm radical polymerization ntawm STRYREE monomers, yog qhov tsis muaj xim nrog lub teeb kev hloov pauv ntawm txog 90%. PS Cov khoom ua pov thawj tsis zoo, tsis muaj tshuaj lom, thiab muaj cov tshuaj tsis ruaj khov, thiab muaj cov tshuaj zoo tiv thaiv aqueous tsis kam rau cov kuab tshuaj. PS Cov khoom lag luam yog tus txawb xov xwm ntawm chav sov thiab nquag kis lossis tawg thaum poob. Qhov nyiaj ntau tshaj plaws yuav tsum tsis pub tshaj 80 ° C, thiab nws tsis tuaj yeem yauv tsis muaj kom tsis muaj sij hawm kub ntawm kev kub siab thiab ua kom nrov ntawm 121 ° C. Hloov chaw, Electron nqaj kom tsis muaj menyuam ua kom tsis muaj menyuam lossis tshuaj lom neeg kom tsis muaj neeg tuaj yeem xaiv tau.

Enzyme-labed daim hlau, cell kev cai consumabables, thiab ntshav pipettes yog txhua yam ua los ntawm polystyrene (ps) ua lawv cov khoom siv raw.

PE (Polyethylene)

Polyethylene, hais tawm raws li PE, yog ib qho thermoplastic resin tau los ntawm polymerization ntawm ethylene monomers. Nws tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab muaj lub waxy. PE Cov Khoom Taw Qhia Zoo qis qis-kub tsis kam (nrog tsawg kawg usable kub xws li -100 rau -70 ° C). Nws ua mos nyob ntawm qhov kub thiab yog opaque.

Zoo li lwm cov polyolefin, polyethylene yog cov khoom siv inert cov khoom siv nrog tshuaj muaj kev ruaj khov. Vim yog cov pa roj carbon-carbon-carbon polbonen molecules, nws tuaj yeem tiv thaiv cov acetone, acces acids nrog oxidizing cov khoom siv tuaj yeem ua rau nws oxidize thiab ua nkig.

Reagent fwj, pipettes, ntxuav hwj, thiab lwm yam kev siv tau yog ua los ntawm polyethylene (PE) cov khoom siv.

PC (Polycarbonate)

Polycarbonate, tseem hu ua PC yas, yog cov polymer nrog pab pawg carbonate hauv nws cov molecular. Nws ua kom zoo ua kom nruj thiab nruj, ua rau nws tiv taus tawg. Ib qho ntxiv, nws muaj cov cua sov ua kom tsis kam thiab hluav taws xob tiv taus, sib ntsib cov cai kom muaj kev kho kom muaj qhov kub thiab txias

Polycarbonate yog tiv thaiv cov kua qaub tsis muaj zog, hauv paus tsis muaj zog, thiab cov roj nruab nrab. Txawm li cas los xij, nws tsis tiv thaiv ultraviolet lub teeb thiab lub hauv paus muaj zog.

Ua kom khov thawv, qee qhov sib nqus Stirrer cog cov tes tsho, thiab Erlenmeyer Flasks yog ua los ntawm polycarbonate (pc) khoom.

Qhov saum toj no piav qhia ntau cov ntaub ntawv siv rau kev kuaj nrhiav cov khoom siv. Feem ntau, cov ntaub ntawv no tuaj yeem raug xaiv yam tsis muaj kev xav tau tshwj xeeb. Yog tias qhov kev sim muaj cov kev cai tshwj xeeb, ib tus tuaj yeem txiav txim siab xaiv cov ntaub ntawv uas ua tau raws li qhov yuav tsum tau ua lossis kho cov khoom uas koj xav tau.
