Abstract:
Nakuba izitsha zesampula zincane, ulwazi oluningi luyadingeka ukuze zisetshenziswe ngendlela efanele.Uma kunezinkinga ngemiphumela yethu yokuhlola, sihlala sicabanga ngamabhodlela esampula okokugcina, kodwa kuyisinyathelo sokuqala okufanele sicatshangelwe.Lapho ukhetha izitsha zesampula ezifanele zohlelo lwakho lokusebenza, udinga ukwenza izinqumo ezintathu: i-septa, isivalo, kanye nezitsha ngokwazo.
01 Septa Umhlahlandlela Wokukhetha
I-PTFE: Inconyelwe umjovo owodwa, Ukumelana ne-solvent enhle kakhulu nokuhambisana kwamakhemikhali* akukho ukubekwa uphawu kabusha ngemva kokubhoboza, Ukugcinwa isikhathi eside kwamasampula akunconywa
I-PTFE / asilicone: inconyelwe imijovo eminingi nokugcinwa kwesampula, izici ezinhle kakhulu zokuvala kabusha, Inokumelana namakhemikhali kwe-PTFE ngaphambi kokubhoboza, kanye nokuhambisana kwamakhemikhali kwe-silicone ngemuva kokubhoboza, Ububanzi bokushisa obusebenzayo ngu-40 ℃ kuya ku-200 ℃
I-PTFE / i-silicone ehlukaniswe ngaphambili:ukunikeza umoya omuhle ukuvimbela ukwakheka kwe-vacuum ku-vials yesampula, ngaleyo ndlela kuzuzwe ukukhiqizwa kabusha kwesampula okuhle kakhulu, Ukuqeda ukuvinjelwa kwenaliti engezansi ngemva kwesampula, Ikhono elihle lokuvala kabusha, Kunconywa imijovo eminingi, Ububanzi bokushisa obusebenzayo ngu-40 ℃ kuya ku-200 ℃
(i-star slit )PE ngaphandle kwe-septa: Inezinzuzo ezifanayo njenge-PTFE
02 Isampula ye-Vials cap Guide
Kunezinhlobo ezintathu zamakepisi we-vials: i-crimp cap, i-snap cap ne-screw cap.Indlela yokubeka uphawu ngayinye inezinzuzo zayo.
amakepisi ama-crimp: Ikepisi lokuqinisa likhama i-septa phakathi konqenqema lwebhodlela lesampula lezitsha zengilazi kanye nekepisi eligoqiwe le-aluminium.Umphumela wokuvala muhle kakhulu, ongavimbela ngempumelelo ukuhwamuka kwesampula.Indawo ye-septum ihlala ingashintshile lapho isampula ibhobozwa ngomjovo ozenzakalelayo.Kuyadingeka ukusebenzisa i-crimper ukuze uvale izitsha zesampula.Kumasampula enani elincane, i-crimper yezandla iyisinqumo esingcono kakhulu.Ngenani elikhulu lamasampuli, i-crimper ezenzakalelayo ingasetshenziswa.
i-snap cap: I-snap cap iyisandiso semodi yokuvala yamakepisi ama-crimp.Isigqoko sepulasitiki esisonqenqemeni lwezitsha zesampula sakha uphawu ngokucindezela i-septa phakathi kwengilazi nesivalo sepulasitiki esinwetshiwe.Ukushuba kwesembozo sepulasitiki kungenxa yomzamo wayo wokubuyisela usayizi wayo wangempela.Ukungezwani kwenza uphawu phakathi kwengilazi, ikepisi kanye ne-septa.Isembozo se-snap sepulasitiki singavalwa ngaphandle kwanoma yimaphi amathuluzi.Umphumela wokuvala wekhava ye-snap awumuhle njengezinye izindlela ezimbili zokuvala.· uma ukulingana kwekepisi kuqine kakhulu, isivalo sinzima ukuvala futhi singase siphuke. Uma ixega kakhulu, umphumela wokuvala uzoba mubi, futhi i-septa ingase ishiye indawo yayo yasekuqaleni.
Isikulufi sekepisi: Ikepisi lesikulufu likhona jikelele.Ukuqinisa ikepisi kusebenzisa amandla acindezela i-septa phakathi kwerimu yengilazi nesivalo se-aluminium.Enqubweni yokukhipha amasampula, umphumela wokuvala we-screw cap muhle kakhulu, futhi i-gasket isekelwa izindlela zemishini.Awekho amathuluzi adingekayo ukuze kuhlanganiswe.
I-PTFE / i-silicone septa ye-screw cap igxilwe ku-polypropylene vials cap ngenqubo ye-non-solvent bonding.Ubuchwepheshe bokuhlanganiswa buklanyelwe ukuqinisekisa ukuthi i-septa nekepisi kuhlala kuhlangene ngesikhathi sokuthutha nalapho ikepisi lifakwa ezitsheni zesampula.Lokhu kunamathela kusiza ukuvimbela i-septa ukuthi ingawi futhi inyakaze ngesikhathi sokusetshenziswa, kodwa indlela yokuvala eyinhloko kusengamandla omshini asetshenziswa lapho ikepisi lijikijelwa ezitsheni zesampula.
Indlela yokuqinisa i-cap iwukwenza uphawu nokugcina i-septa isendaweni efanele ngesikhathi sokufakwa kwe-probe.Akudingekile ukugoqa i-cap ngokuqinile kakhulu, ngaphandle kwalokho kuzothinta ukuvala futhi kubangele ukuthi i-septa iwe futhi idlulise.Uma ikepisi liqiniswe kakhulu, i-septa izoba inkomishi noma iboleke.
03 Impahla yezitsha zesampula
Uhlobo I, 33 line-expension borosilicate glass:Iyingilazi engasebenzi amakhemikhali kakhulu njengamanje.Ngokuvamile isetshenziswa kumalabhorethri okuhlaziya ukuze kutholwe imiphumela yokuhlola yekhwalithi ephezulu.I-coefficient yayo yokunweba icishe ibe ngu-33x10 ^ (- 7) ℃, ehlanganiswe kakhulu ne-silicon oxygen, futhi iqukethe i-trace boron ne-sodium.Zonke izitsha zengilazi zamanzi ziwuhlobo I-33 yengilazi yokukhulisa umugqa.
Thayipha I, ingilazi yomugqa wama-50 yokukhulisa: Ine-alkaline kunengilazi yokukhulisa umugqa wama-33 futhi ingasetshenziswa ezinhlotsheni zezicelo zaselabhorethri.I-coefficient yayo yokunweba icishe ibe ngu-50x 10 ^ (- 7) ℃, eyakhelwe kakhulu i-silicon nomoya-mpilo, futhi iqukethe inani elincane le-boron.Izitsha eziningi zengilazi ze-Hamag amber zenziwe ngengilazi yokukhulisa engama-50.
Thayipha I, ingilazi yomugqa womugqa wama-70: Iyonga kakhulu kunengilazi yomugqa womugqa ongu-50 futhi ingasetshenziswa ezinhlotsheni zezicelo zaselabhorethri.I-coefficient yayo yokunweba icishe ibe ngu-70x 10 ^ (- 7) ℃, eyakhelwe kakhulu i-silicon nomoya-mpilo, futhi iqukethe inani elincane le-boron.Inani elikhulu lamabhodlela e-Hamag acacile enziwe ngengilazi yokwandisa engama-70.
I-Deactivated glass (DV): Kuma-analytes ane-polarity eqinile futhi ebophezela endaweni yengilazi epholile yengilazi, ukuvala izitsha zesampula kungase kube ukukhetha okuhle.Indawo yengilazi ye-Hydrophobic yakhiqizwa ukwelashwa kwe-silane okusebenzayo esigabeni sengilazi.Izitsha zesampula ezingasasebenzi zingamiswa futhi zigcinwe unomphela.
Amapulasitiki e-Polypropylene: I-Polypropylene (PP) iyipulasitiki engasasebenzi engasetshenziswa lapho ingilazi ingafaneleki khona.Izitsha zesampula ze-polypropylene zisengagcina ukuvala kahle lapho zishisiwe, ngaleyo ndlela kuncishiswe amathuba okuchayeka ezintweni ezingaba yingozi.Izinga lokushisa eliphezulu lokusebenza ngu-135 ℃.
