Ibisobanuro:
Nubwo inzabya ntangarugero ari nto, ubumenyi bunini burasabwa kubikoresha neza.Iyo hari ibibazo nibisubizo byubushakashatsi, burigihe duhora dutekereza kubibindi byanyuma, ariko nintambwe yambere yo gusuzuma.Mugihe uhisemo icyitegererezo gikwiye kubisabwa, ugomba gufata ibyemezo bitatu: septa, umupfundikizo, hamwe na viali ubwayo.
01 Igitabo cyo Guhitamo Septa
PTFE: irasabwa gutera inshinge imwe, Kurwanya solvent nziza hamwe no guhuza imiti * nta re kashe nyuma yo gutobora, Kubika igihe kirekire byintangarugero ntibisabwa
PTFE / silicone: isabwa gutera inshinge nyinshi hamwe nububiko bwikitegererezo, Ikiranga cyiza cyo gufunga ibimenyetso, Ifite imiti irwanya PTFE mbere yo gutobora, hamwe n’imiti ihuza silicone nyuma yo gutobora, Ubushyuhe bwo gukora ni - 40 ℃ kugeza 200 ℃
Mbere yo gutobora PTFE / silicone:tanga umwuka mwiza kugirango wirinde ko habaho icyuho mubikarito by'icyitegererezo, bityo ukagera ku myororokere myiza y’icyitegererezo, Kurandura inzitizi yo hasi nyuma yo gutoranya, Ubushobozi bwiza bwo gufunga, Birasabwa gutera inshinge nyinshi, Ubushyuhe bwo gukora ni - 40 200 kugeza 200 ℃
(inyenyeri yinyenyeri) PE idafite septa: Ifite ibyiza bimwe na PTFE
02 Icyitegererezo cya vial cap
Hariho ubwoko butatu bwibikoresho bya vial: capimp cap, snap cap na screw cap.Buri buryo bwo gushiraho ikimenyetso bufite inyungu zabwo.
ingofero ya capimp: Igipfundikizo cya clamp gikanda septa hagati yikibindi cyuruhande rwikirahure cyikirahure nicyuma cya aluminiyumu.Ingaruka yo gufunga ni nziza cyane, irashobora gukumira neza ibyuka bihumeka.Umwanya wa septum ntigihinduka mugihe icyitegererezo cyacumiswe binyuze mumashanyarazi yikora.Birakenewe gukoresha crimper kugirango ushireho kashe ya sample.Kubito bike byintangarugero, intoki crimper ninziza nziza.Kumubare munini wintangarugero, crimper yikora irashobora gukoreshwa.
Igifuniko cya snap: Igifuniko cya snap ni kwagura uburyo bwo gufunga kashe ya capimp.Igipapuro cya plastiki kumpera yikibindi cyicyitegererezo gikora kashe mukunyunyuza septa hagati yikirahure nigitambaro cyagutse cya plastiki.Impagarara mu gipfukisho cya plastiki ziterwa no kugerageza kugarura ingano yumwimerere.Impagarara zikora kashe hagati yikirahure, ingofero na septa.Igifuniko cya plastiki gishobora gufungwa nta bikoresho na kimwe. Ingaruka yo gufunga igifuniko cya snap ntabwo ari nziza nkubundi buryo bubiri bwo gufunga. Niba irekuye cyane, ingaruka zo gufunga zizaba mbi, kandi septa irashobora kuva mumwanya wambere.
Igipfundikizo cya shitingi: Igipapuro cya screw ni rusange.Kwizirika ingofero bigira imbaraga zumukanishi ukanda septa hagati yikirahure na capit ya aluminium.Muburyo bwo gutobora icyitegererezo, ingaruka zo gufunga imipira ya screw ni nziza, kandi gasketi ishyigikiwe nuburyo bwa mashini.Nta bikoresho bisabwa mu guterana.
PTFE / silicone septa ya capa ya screw yashyizwe kumurongo wa polypropilene vial cap hamwe nuburyo budahwitse.Tekinoroji yo guhuza igenewe kwemeza ko septa na capi bihora hamwe mugihe cyo gutwara no mugihe ingofero ishyizwe kumashanyarazi.Uku gufatira hamwe gufasha kurinda septa kugwa no guhindagurika mugihe cyo kuyikoresha, ariko uburyo nyamukuru bwo gufunga ni imbaraga za mashini zikoreshwa mugihe ingofero yometse kumashanyarazi.
Uburyo bwo gufunga cap ni ugukora kashe no kugumisha septa mumwanya mwiza mugihe cyo gushiramo iperereza.Ntabwo ari ngombwa gusunika ingofero cyane, bitabaye ibyo bizagira ingaruka kuri kashe kandi bitera septa kugwa no kwimura.Niba ingofero isunitswe cyane, septa izakopa cyangwa iryamye.
03 Ibikoresho by'icyitegererezo
Ubwoko bwa I, 33 umurongo-wagura ibirahuri bya borosilicate: Nicyo kirahure cyimiti cyane muri iki gihe.Ubusanzwe ikoreshwa muri laboratoire isesengura kugirango ibone ibisubizo byiza byubushakashatsi.Coefficient yayo yo kwaguka igera kuri 33x10 ^ (- 7) ℃, igizwe ahanini na ogisijeni ya silikoni, kandi ikubiyemo boron na sodium.Ibirahuri by'amazi byose ni ubwoko bwa I 33 umurongo-wagura ikirahure.
Ubwoko bwa I, ibirahuri 50-byerekana ikirahure: Ni alkaline kuruta ibirahuri 33-byerekana umurongo kandi birashobora gukoreshwa mubikorwa bitandukanye bya laboratoire.Coefficient yayo yo kwaguka igera kuri 50x 10 ^ (- 7) ℃, igizwe ahanini na silikoni na ogisijeni, kandi irimo na boron nkeya.Ibirahuri byinshi bya Hamag amber bikozwe mubirahuri 50 byo kwagura.
Ubwoko bwa I, 70 umurongo-wo kwagura ikirahure: Nubukungu burenze 50 umurongo-wo kwagura umurongo kandi urashobora gukoreshwa mubikorwa bitandukanye bya laboratoire.Kwiyongera kwayo ni 70x 10 ^ (- 7) ℃, igizwe ahanini na silikoni na ogisijeni, kandi irimo na boron nkeya.Umubare munini wibikoresho bisobanutse bya Hamag bikozwe mubirahuri 70 byo kwaguka.
De ibirahuri bikora (DV): Kubisesengura bifite polarite ikomeye kandi bihambiriye hejuru yikirahure cyikirahure cyikirahure, gukuraho vial sample bishobora kuba amahitamo meza.Hydrophobique yikirahure yakozwe no kuvura silane ikora mugice cyikirahure.Ibikoresho by'icyitegererezo byahagaritswe birashobora gukama no kubikwa igihe kitazwi.
Amashanyarazi ya polypropilene: Polypropilene (PP) ni plastiki idakora neza ishobora gukoreshwa aho ikirahuri kidakwiriye.Icyitegererezo cya polypropilene kirashobora gukomeza gufunga neza iyo cyatwitswe, bityo bikagabanya amahirwe yo guhura nibintu bishobora guteza akaga.Ubushyuhe ntarengwa bwo gukora ni 135 ℃.
