Pre-slit ptfe \ abicone septa

Ufuna ukwazi ulwazi oluphelele mayelana ne-PTFE \ abicone septa, sicela uhlole le ndatshana: Konke odinga ukukwazi: 137 pre-slit ptfe \ airtone septa FAQs

Yini kuqala i-Sentat Septa?

I-Pre-Slit Septa ukuvalwa kwe-vial nge-slit eyenziwe ngaphambili evumela ukungena okulula ngezinaliti ezisetshenziswa kuma-autosamplers. Lesi sici sokuklama siwusizo ikakhulukazi kuma-labs adinga ukuvumelanisa isampula noma ejova kusuka ku-vial efanayo. I-Pre-Slit Septa isuse inaliti ephansi ye-Clogling ngemuva kokusampula. I-slit ivumela inaliti ukufinyelela isampula ngaphandle kokuthi kwenziwe ukubhoboza okusha ngasikhathi sinye, esisiza ukugcina ubuqotho be-vial seal.

Pre-slit ptfe \ abicone septa bakhiwa ngezinto ezimbili eziphambili:

Isendlalelo se-Ptfe: Le ngqimba inikeza ukumelana kahle kwamakhemikhali, ukukhishwa okuphansi, nokuchitheka okuncane kwezinhlayiyana. I-PTFE yaziwa ngokuvuselelwa kwayo, okwenza ilungele ukwahlukana okuhlukahlukene kwamakhemikhali namakhemikhali asetshenziswa kakhulu kumakhemikhali wokuhlaziya.

I-Silicone ungqimba: Ingxenye ye-silicone ingeza amandla nokuqina kwe-Septum. Kuthuthukisa amandla okukokuzalwa kabusha ngemuva kokubhoboza inaliti, ukuqinisekisa ukuthi amasampula avikelekile ekungcolisweni nasekuhanjisweni.

Inhlanganisela yalezi zinto zokwenziwa ikhiqiza i-septum engamelana nama-punctures aphindaphindekile futhi ilondoloze uphawu olunokwethenjelwa.

Izinzuzo ze-Pre-Slit Septa

1. I-Pre-Slit Septa yenza lula inqubo yokujova yesampula. I-pre-slits ivumela izinaliti ezinhle ukungena kalula, zinciphise amandla adingekayo ukubhoboza i-septum. Lesi sici sizuzisa ikakhulukazi izinhlelo ezenzakalelayo lapho ijubane nokusebenza kahle kubaluleke kakhulu.

2. Inzuzo esemqoka ye-Pre-Slit Septa yikhono labo lokunciphisa ukugoba inaliti ngesikhathi sokukhishwa kwesampula. Ukusikwa kuhlinzeka ngendawo yokungena engaguquki yenaliti, kusiza ukugcina ukuqondanisa nokunciphisa ukuhlukahluka kuma-engeli lomjovo. Lesi sici sokuklama sinciphisa amathuba okulimala kwenaliti, ngaleyo ndlela ugweme ukungcoliswa noma ukungcoliswa kwesampula okungahambelani.

I-3. Isendlalelo se-silicone sithuthukisa amandla okusola kabusha ngemuva kokungena ngenaliti. Lesi sici sibalulekile ukuthi izinhlelo zokusebenza ezidinga imijovo eminingi kusuka ku-vial efanayo, ngoba kusiza ukugcina uphawu oluqinile, ukuvimbela ukuhwamuka kwesampula nokungcola phakathi kwemijovo.

I-4. I-Pre-cut Septa ihlinzeka ngomoya omncane wokuthola umoya omuhle ukuvikela ukwakheka kwe-vacuum ngaphakathi kwesampula yesampula, ngaleyo ndlela ifinyelele ekuvuseleleni kahle kwesampula. I-Pre-cut Septa ingakhipha ngempumelelo ingcindezi ye-vacuum ngesikhathi somjovo omkhulu wevolumu. Lesi sici sivimbela izinkinga ezingaba khona ezihambisana nokuqongelelwa kwengcindezi ngaphakathi kwe-vial, ngaleyo ndlela sigweme ukulahleka kwesampula noma ukungcoliswa.

I-5. I-Pre-cut Septa iyahambisana nezinhlobo ezahlukene zama-autosampler syringes, kufaka phakathi lezo ezenziwe ngensimbi ne-peek (polytheketoone). Lokhu kuguqulwa okuvumela ama-laboratories ukuthi akhethe isirinji ngokuya ngezidingo zabo ezithile ngaphandle kokukhathazeka ngezinkinga zokuhambisana.

Qhathanisa ne-non-silt Septa

Ngenkathi i-septa yangaphambi kokusika inezinzuzo eziningi, non-silt Septa zivame ukusetshenziswa ezindaweni zelebhu.

Ukusetshenziswa kabusha: I-Non-Silt Septa inokuphambuka okuhle kakhulu ngemuva kwentuthuko yenaliti, esiza ukunciphisa ukungcoliswa kwe-Carrover phakathi kwamasampula.

Isitoreji Eside: Non-siltI-Septe ingasetshenziselwa imijovo eminingi kanye nesitoreji sesampula. Lezi zimbobo zivame ukunconyelwa ukugcinwa isikhathi eside kwamasampula ngoba zikwazi ukugcina uphawu olunzima lapho lungasebenzi.

Ukuvikelwa kusuka ekuhwamukayo: Non-silt Septa nikeza ukuvikela okungcono ekuhwaleni ngaphambi kokubhobozwa, kubenze balungele amasampula aguqukayo angahle avele ngokushesha.

Ufuna ukwazi ukuthi ukhetha iSepta ku-Pre-Slit noma cha? Sicela ubheke le ndatshana: Ungayikhetha kanjani i-Septa Preta Pre-Slit noma cha?

Ukucatshangelwa lapho ukhetha i-Septe

Lapho ukhetha phakathi kokulala kwangaphambili nokungabizi, kunezici eziningana okufanele zicatshangelwe:

1. Uhlobo lwesampula oluhlaziywa luzothonya ukukhetha kokukhethwa kwezinto ze-Septum. Isibonelo, uma izixazululo ezilonakalisayo noma amakhompiyutha asebenzayo zisetshenziswa, ukuqinisekisa ukuhambisana ne-PTFE kanye nezendlalelo ze-silicone kubalulekile.

2. Uma udlulisa isampula noma uhlaziya ama-vial kaninginingi, i-Pre-Slit Septa inikezela lula kanye nokusebenza kahle. Ngakolunye uhlangothi, i-Senta e-non-slit ingahle ilunge ngokwengeziwe uma kugcinwa isitoreji esihlala isikhathi eside futhi ukufinyelela kungajwayelekile.

3. Ukukhethwa kwenaliti yokuhlunga nakho kuzothonya isinqumo. I-Pre-Slit Septa ilungele izinaliti ezimnene, kanti ama-septa angezona angejwayelekile angahle alungele kangcono izinaliti ezinkulu ezidinga uphawu olunzima.

4. Pre-cut Septa ube nebanga lokushisa elisebenzayo le -40 ° C kuya ku-200 ° C; iningi langaphambi-isibulali I-PTFE \ Silicone Septa ingamelana namazinga okushisa aze afike ku-200 ° C, kepha angahluka ngokuya ngendlela ethile.

Izicelo ze-Pre-Silt Septa

I-Pre-Silt Septa isetshenziswa kabanzi ezinhlobonhlobo zezicelo ku-Analytical Chemistry:

Ukuhlaziywa Kwezemvelo: Ekuqapheni kwezemvelo, amasampula adinga ukukhishwa kaningi kusuka kuma-vial aqukethe ama-compacts ajwayelekile we-organic (ama-Vocs), kanye ne-Pre-cut Septa yenza lula isampula ngokushesha.

Ukuhlolwa Kwemithi: Ezindaweni zokuhlinzekwa kwezemithi lapho kudingeka khona imijovo ye-dosing kanye nemijovo ephindaphindiwe, lezi ze-septa zithuthukisa ukuphindwaphindwa futhi zinciphise ukungcoliswa kokuwela.

Ukuhlolwa kokuphepha kokudla: Ezihlolweni zokuhlaziywa kokudla lapho amakhompiyutha aguqukayo kufanele abhekwe khona, pre-isibulali I-Septe inika amandla isampula esebenzayo ngaphandle kokuyekethisa ubuqotho besampula.

Pre-isibulali Ptfe \ abicone septa ziyizakhi ezibalulekile kwelebhu yanamuhla yokuhlaziya isebenzisa ama-chromatography kaphethiloli kanye namasu obuningi be-spectrometry. Zenzelwe ukusebenziseka kalula, ukuvela kabusha okuthuthukile, kuncishiswe izingqinamba ezihlobene nenaliti, futhi ngempumelelo ezindaweni ezingena phezulu. Ukuhlanganisa ukumelana kwamakhemikhali kwe-PTFE ngokuqina kwe-silicone, lezi ze-septa zinikeza isixazululo esisebenzayo sokugcina ubuqotho besampula ezinhlobonhlobo zezicelo ku-analytical chemistry. Ngokuqonda izinzuzo ezihlukile nokulinganiselwa kwenketho ngayinye, abahlaziyi bangaqinisekisa ukuthi ukukhetha kwabo kuzosekela imiphumela eqondile nethembekile emsebenzini wabo wokuhlola.
