Inkcazo:
Nangona iibhotile zesampulu zincinci, ulwazi oluninzi luyafuneka ukuze lusetyenziswe ngokufanelekileyo.Xa kukho iingxaki kwiziphumo zethu zovavanyo, sihlala sicinga ngeebhotile zesampulu zokugqibela, kodwa linyathelo lokuqala ekufuneka liqwalaselwe.Xa ukhetha iibhotile zesampulu ezifanelekileyo kwisicelo sakho, kufuneka wenze izigqibo ezintathu: i-septa, isiciko, kunye neengqayi ngokwayo.
01 Septa Isikhokelo sokuKhetha
I-PTFE: Kucetyiswa ukuba kufakwe inaliti enye, ukuxhathisa okugqwesileyo kwe-solvent kunye nokuhambelana kweekhemikhali* akukho kutywinwa kwakhona emva kokugqojozwa, ukugcinwa kwexesha elide kweesampuli akukhuthazwa.
I-PTFE / i-silicone: icetyiswa kwiinaliti ezininzi kunye nokugcinwa kwesampulu, iimpawu ezigqwesileyo zokutywinwa kwakhona, Inokumelana nemichiza ye-PTFE ngaphambi kokugqobhozwa, kunye nokuhambelana kwemichiza ye-silicone emva kokuhlatywa, Uluhlu lobushushu obusebenzayo ngu-40 ℃ ukuya kwi-200 ℃
I-PTFE yangaphambili / i-silicone:ukubonelela ngendawo yokungena komoya efanelekileyo ukuthintela ukubunjwa kwevacuum kwisitya sesampulu, ngaloo ndlela kufezekiswa ukuveliswa kwakhona kwesampulu, Ukuphelisa ukuvaleka kwenaliti esezantsi emva kwesampulu, isakhono esihle sokutywinwa kwakhona, Kucetyiswa ukuba kufakwe iinaliti ezininzi, Uluhlu lobushushu bokusebenza ngu-40 ℃ ukuya kuma-200 ℃
(i-slit star )PE ngaphandle kwe-septa: Ineenzuzo ezifanayo njenge-PTFE
02 Isampula yeebhotile zeSikhokelo
Kukho iindidi ezintathu zeevials caps: i-crimp cap, i-snap cap kunye ne-screw cap.Indlela yokutywina nganye ineengenelo zayo.
I-crimp caps: I-clamp cap icinezela i-septa phakathi kwee-vials ze-vials zesampulu zeglasi kunye ne-aluminiyam esongwayo.Isiphumo sokutywinwa silungile kakhulu, esinokuthi sithintele ngokufanelekileyo ukuvela kwesampulu.Isikhundla se-septum sihlala singatshintshi xa isampuli ihlatywa nge-injector ngokuzenzekelayo.Kuyimfuneko ukusebenzisa i-crimper ukutywina iibhotile zesampuli.Kwiisampulu zobungakanani obuncinci, i-crimper ye-manual lolona khetho lungcono.Kwinani elikhulu leesampuli, i-crimper ezenzekelayo ingasetyenziswa.
i-snap cap: I-snap cap lulwandiso lwendlela yokutywina ye-crimp caps.I-cap yeplastiki kumda we-vials yesampuli yenza itywina ngokucinezela i-septa phakathi kweglasi kunye ne-cap yeplastiki eyandisiweyo.Uxinzelelo kwikhava yeplastiki kungenxa yokuzama ukubuyisela ubungakanani bayo bokuqala.Uxinzelelo lwenze itywina phakathi kweglasi, ikepusi kunye nesepta.Isigqubuthelo seplastiki sokuvala singavalwa ngaphandle kwezixhobo.Isiphumo sokutywina sesigqubuthelo esikhawulezayo asilunganga njengezinye iindlela ezimbini zokutywina.· ukuba ukulingana kwekepusi kuqinile kakhulu, ikepusi kunzima ukuyivala kwaye inokwaphuka. Ukuba ikhululekile kakhulu, isiphumo sokutywinwa siya kuba sibi, kwaye i-septa inokushiya indawo yayo yokuqala.
Screw cap: I-screw cap iyinto yonke.Ukuqinisa ikepusi kusebenzisa amandla omatshini acudisa i-septa phakathi kwerim yeglasi kunye nesivalo se-aluminiyam.Kwinkqubo ye-puncturing isampuli, umphumo wokutywinwa kwe-screw cap ugqwesileyo, kwaye i-gasket ixhaswa ngeendlela zoomatshini.Akukho zixhobo zifunekayo ukuze uhlanganise.
I-PTFE / i-silicone septa ye-screw cap igxininiswe kwi-polypropylene vials cap ngenkqubo ye-nonsolvent bonding.Itekhnoloji yokudibanisa yenzelwe ukuqinisekisa ukuba i-septa kunye ne-cap zihlala zihlangene ngexesha lokuthutha kwaye xa i-cap ifakwe kwi-vials yesampuli.Oku kubambelela kunceda ukuthintela i-septa ukuba ingawi kwaye iguquguquke ngexesha lokusetyenziswa, kodwa eyona ndlela yokutywina isengamandla omatshini asetyenziswa xa i-cap ikrwelwe kwi-vials yesampuli.
Indlela yokuqinisa i-cap kukwenza isitywina kwaye ugcine i-septa kwindawo echanekileyo ngexesha lokufakwa kweprobe.Akuyimfuneko ukukrazula i-cap ngokuqinileyo, ngaphandle koko kuya kuchaphazela ukutywinwa kwaye kubangele ukuba i-septa iwe kwaye idlulise.Ukuba ikepusi ijijwe ngokuqinileyo, i-septa iya kuba nekomityi okanye iboboke.
03 Izinto eziphathekayo zeebhotile zesampuli
Uhlobo I, 33 line-expension borosilicate glass: Yeyona glass inert kakhulu khemikhali okwangoku.Idla ngokusetyenziswa kwiilabhoratri zohlalutyo ukufumana iziphumo zovavanyo ezikumgangatho ophezulu.Ukwandiswa kwe-coefficient yayo malunga ne-33x10 ^ (- 7) ℃, eyona nto yenziwe nge-silicon oksijini, kwaye iqulethe i-trace boron kunye ne-sodium.Zonke iingqayi zeglasi yamanzi luhlobo I 33 line-expension glass.
Uhlobo I, iglasi ye-50 yokwandisa umgca: Ingaphezulu kwe-alkaline kune-33 yeglasi yokwandisa umgca kwaye ingasetyenziselwa kwizicelo ezahlukeneyo zebhubhoratri.I-coefficient yayo yokwandisa malunga ne-50x 10 ^ (- 7) ℃, eyona nto ihlanganiswe ne-silicon kunye ne-oxygen, kwaye iqulethe ixabiso elincinci le-boron.Uninzi lweengqayi zeglasi ze-Hamag amber zenziwe ngeglasi yokwandisa engama-50.
Uhlobo I, iglasi ye-70 yokwandisa i-line-expension: I-economic ngaphezu kwe-50 ye-line-expension glass kwaye ingasetyenziselwa kwiindidi zezicelo zebhubhoratri.I-coefficient yayo yokwandisa malunga ne-70x 10 ^ (- 7) ℃, eyona nto yenziwe nge-silicon kunye ne-oxygen, kwaye iqulethe inani elincinci le-boron.Ubungakanani obukhulu bee-Hamag izitya ezicacileyo zenziwa kwi-70 yeglasi yokwandisa.
I-Deactivated glass (DV): Kubahlalutyi abane-polarity eyomeleleyo kunye nokubophelela kwindawo yeglasi yeglasi yeglasi, ukucima i-vials yesampuli kunokuba lukhetho oluhle.Umphezulu weglasi we-Hydrophobic uveliswe ngonyango lwe-silane olusebenzayo kwisigaba seglasi.Iibhotile zeesampuli ezingasebenziyo zinokomiswa kwaye zigcinwe ngokungenasiphelo.
Iiplastiki zePolypropylene: I-Polypropylene (PP) yiplastiki engasebenziyo enokusetyenziswa apho iglasi ingafanelekanga.Iisampulu zeesampulu zeesampulu zePolypropylene zisenako ukugcina ukutywinwa okulungileyo xa zitshisiwe, ngaloo ndlela kuncitshiswe amathuba okuba sesichengeni kwizinto ezinokuba yingozi.Ubushushu obuphezulu bokusebenza yi-135 ℃.
