Ibikoresho bisanzwe bikoreshwa muri plastiki muri laboratoire

Hariho ibintu bitandukanye bigerageza.Usibye ibirahuri bikoreshwa mubirahure, bikunze gukoreshwa ni ibikoresho bya plastiki.Noneho uzi ibikoresho ibikoresho bya plastiki bikoreshwa mubuzima bwa buri munsi bikozwe?Ni ibihe bintu biranga?Nigute ushobora guhitamo?Reka dusubize umwe umwe nkuko biri hepfo.

Ibikoresho bya plastiki bikoreshwa muri laboratoire ahaniniinama, centrifuge tubes,Ibyapa bya PCR, ibyokurya byumuco utugari / amasahani / amacupa, cryovial, nibindi byinshi mubyifuzo bya pipette, amasahani ya PCR, cryovial nibindi bikoreshwa bikoreshwa ni PP.Ibikoresho (polypropilene),umuco wumudugudu ukoreshwamuri rusange bikozwe muri PS (polystirene), flasque yumuco w'akagari ikozwe muri PC (polyakarubone) cyangwa PETG (polyethylene terephthalate copolymer).

1. Polystirene (PS)

Ifite urumuri rwiza kandi ntabwo rufite uburozi, hamwe n’urumuri rwa 90%.Ifite imiti irwanya imiti, ariko irwanya imiti.Ifite inyungu zimwe zigereranije nizindi plastiki.Gukorera mu mucyo no gukomera.

Ibicuruzwa bya PS birasa nubushyuhe bwicyumba kandi bikunda gucika cyangwa kumeneka iyo byamanutse.Ubushyuhe bukomeza gukoreshwa ni 60 ° C, kandi ubushyuhe ntarengwa bwo gukoresha ntibugomba kurenga 80 ° C.Ntishobora guterwa n'ubushyuhe bwinshi n'umuvuduko mwinshi kuri 121 ° C.Urashobora guhitamo ibikoresho bya elegitoroniki cyangwa kuvanga imiti.

Amacupa yumuco wa selile ya Shandong Labio, ibyokurya byumuco utugari, amasahani yumuco, hamwe na pipeti ya serologiya byose bikozwe muri polystirene (PS).

2. Polypropilene (PP)

Imiterere ya polypropilene (PP) isa na polyethylene (PE).Nibikoresho bya termoplastique bikozwe muri polymerisation ya propylene.Mubisanzwe ni ibara ritagira ibara rikomeye, ridafite impumuro nziza kandi ridafite uburozi.Inyungu nyamukuru yacyo nuko ishobora gukoreshwa mubushyuhe bwinshi hamwe nubushyuhe bwa 121 ° C.Kurimbuka.

Polypropilene (PP) ifite imiterere yubukanishi no kurwanya imiti.Irashobora kwihanganira kwangirika kwa acide, alkalis, amazi yumunyu hamwe nudukoko dutandukanye kama munsi ya 80 ° C.Ifite ubukana, imbaraga nubushyuhe burenze polyethylene (PE).;Kubijyanye no kurwanya ubushyuhe, PP nayo irarenze PE.Kubwibyo, mugihe ukeneye guhererekanya urumuri cyangwa kwitegereza byoroshye, cyangwa kurwanya umuvuduko mwinshi cyangwa gukoresha ubushyuhe, urashobora guhitamo PP ikoreshwa.

3. Polyakarubone (PC)

Ifite ubukana bwiza no gukomera, ntabwo ivunika byoroshye, kandi ifite imbaraga zo kurwanya ubushyuhe no kurwanya imirasire.Yujuje ibyangombwa byubushyuhe bwo hejuru hamwe n’umuvuduko ukabije wa sterisizione hamwe n’imirasire y’ingufu nyinshi mu murima w’ibinyabuzima.Polyakarubone (PC) irashobora kugaragara mubintu bimwe na bimwe bikoreshwa, nkaagasandukunaflasks ya erlenmeyer.

4. Polyethylene (PE)

Ubwoko bwa resmoplastique resin, idafite impumuro nziza, idafite uburozi, yumva ari ibishashara, ifite ubushyuhe buke bwo kurwanya ubushyuhe (ubushyuhe bwo hasi cyane bushobora kugera kuri -100 ~ -70 ° C), kandi byoroshye byoroshye mubushyuhe bwinshi.Ifite imiti ihamye kuko molekile ya polymer ihujwe binyuze muri karubone-karubone imwe kandi irashobora kurwanya isuri ya acide nyinshi na alkalis (idashobora kurwanya aside ifite imiterere ya okiside).

Muri make, polypropilene (PP) na polyethylene (PE) nubwoko bwa plastiki bukunze kugaragara muri laboratoire.Mugihe uhitamo ibikoreshwa, urashobora guhitamo byombi niba bidakenewe bidasanzwe.Niba hari ibisabwa kugirango ubushyuhe bwo hejuru burushe hamwe nubushyuhe bwo hejuru hamwe na sterisizione yumuvuduko mwinshi, urashobora guhitamo ibikoreshwa bikozwe muri polypropilene (PP);niba ufite ibisabwa kugirango ubushyuhe buke bukore, urashobora guhitamo polyethylene (PE);naho kumico yingirabuzimafatizo ikoreshwa muribyinshi muri byo bikozwe muri polystirene (PS).
