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 iisampulu ezifanelekileyo kwisicelo sakho, kufuneka wenze izigqibo ezithathu: i-septa, isiciko, kunye neengqayi ngokwayo.

01 Septa Isikhokelo sokuKhetha

I-PTFE: Kunconywa inaliti enye, ukuxhathisa okugqwesileyo kwe-solvent kunye nokuhambelana kweekhemikhali* akukho kutywinwa kwakhona emva kokugqojozwa, ukugcinwa kwexesha elide kweesampuli akukhuthazwa.

I-PTFE / i-silicone: inconywa kwiinaliti ezininzi kunye nokugcinwa kwesampulu, iimpawu ezigqwesileyo zokutywinwa kwakhona, Inokumelana nemichiza ye-PTFE ngaphambi kokuhlatywa, kunye nokuhambelana kweekhemikhali ze-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 ebalaseleyo, 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 kweengqayi zeevials zeglasi yesampulu yeglasi 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 isitywina 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 kuhlanganiswe.

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 kwii-vials zesampuli.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 yikomityi 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 yi-silicon oksijini, kwaye iqulethe i-trace boron kunye ne-sodium.Zonke iingqayi zeglasi yamanzi ziluhlobo I 33 line-expension glass.

Uhlobo lwe-I, i-glass ye-50 ye-line-expension glass: I-alkaline ngaphezu kwe-33 ye-glass-expension glass kwaye ingasetyenziselwa kwiindidi ze-laboratory izicelo.I-coefficient yayo yokwandisa malunga ne-50x 10 ^ (- 7) ℃, eyona nto yenziwe nge-silicon kunye ne-oxygen, kwaye iqulethe ixabiso elincinci le-boron.Uninzi lweengqayi zeglasi zeHamag amber zenziwe ngeglasi yokwandisa engama-50.

Uhlobo I, i-70 ye-line-expension glass glass: I-economic ngaphezu kwe-50 ye-glass-expension ye-glass kwaye ingasetyenziselwa kwiindidi zezicelo zebhubhoratri.I-coefficient yayo yokwandisa malunga ne-70x 10 ^ (- 7) ℃, eyona nto ihlanganiswe ne-silicon kunye ne-oxygen, kwaye iqulethe ixabiso elincinci le-boron.Ubuninzi bee-Hamag ezicacileyo ze-vials zenziwe kwi-70 yeglasi yokwandisa.

I-Deactivated glass (DV): Kubahlalutyi abane-polarity eyomeleleyo kunye nokubophelela kwindawo yeglasi epholileyo yeglasi, ukucima i-vials yesampuli kunokuba lukhetho oluhle.Umphezulu weglasi yeHydrophobic uveliswe ngonyango lwe-silane olusebenzayo kwisigaba seglasi.Iibhotile zesampuli ezivaliweyo zinokomiswa kwaye zigcinwe ngokungenasiphelo.

Iiplastiki zePolypropylene: I-Polypropylene (PP) yiplastiki engasebenziyo enokuthi isetyenziswe apho iglasi ingafanelekanga.Iisampulu zeesampulu zeesampulu zePolypropylene zisenako ukugcina ukutywinwa kakuhle xa zitshisiwe, ngaloo ndlela kuncitshiswe ukuba sesichengeni kwizinto ezinokuba yingozi.Ubushushu obuphezulu bokusebenza yi-135 ℃.
