Abstract:
Kunyangwe mabhodhoro emuenzaniso ari madiki, ruzivo rwakakura runodiwa kuti uishandise nemazvo.Kana paine matambudziko nemhedzisiro yedu yekuyedza, isu tinogara tichifunga nezveyemuenzaniso mabhodhoro ekupedzisira, asi idanho rekutanga kufunga.Paunenge uchisarudza mabhodhoro akakodzera echishandiso chako, unofanirwa kuita sarudzo nhatu: septa, chivharo, uye mabhodhoro acho pachawo.
01 Septa Sarudzo Yekutungamira
PTFE: inokurudzirwa jekiseni rimwe chete, Yakanakisa solvent kuramba uye kuenderana kwemakemikari * hapana kuiswa chisimbiso mushure mekuboora, kuchengetwa kwenguva refu kwemasampuli hakukurudzirwe.
PTFE / silicone: inokurudzirwa majekiseni akawanda uye sampuli yekuchengetedza, Yakanakisa yekuisa chisimbiso maitiro, Iine makemikari anopikisa PTFE isati yabaya, uye kuenderana kwekemikari yesilicone mushure mekubaya, Iyo tembiricha yekushanda ndeye - 40 ℃ kusvika 200 ℃
Pre-slit PTFE / silicone:ipai mhepo yakanaka kudzivirira kuumbwa kwevacuum mune yemuenzaniso vials, nekudaro kuwana yakanakisa sampling kuberekana, Bvisa kuvharika kweyezasi tsono mushure mesampling, Yakanaka rekuisa chisimbiso kugona, Inokurudzirwa kune akawanda majekiseni, Iyo tembiricha yekushanda iri -40 ℃ kusvika ku200 ℃
(nyeredzi slit )PE isina septa: Iine mabhenefiti akafanana nePTFE
02 Sample vials cap Guide
Kune marudzi matatu evhavha caps: crimp cap, snap cap uye screw cap.Imwe neimwe nzira yekuisa chisimbiso ine zvayakanakira.
crimp caps: Chivharo chivharo chinosvina septa pakati pemabhodhoro emupendero wegirazi remuenzaniso mabhodhoro uye kapu yealuminium yakapetwa.Iyo yekuisa chisimbiso yakanaka kwazvo, iyo inogona kudzivirira zvinobudirira sampuli kubuda.Nzvimbo ye septum inoramba isina kuchinjwa kana sampuli inoputirwa kuburikidza nejekitori ye otomatiki.Izvo zvinodikanwa kushandisa crimper kuvhara mabhodhoro emuenzaniso.Kune mashoma ehuwandu masampuli, manual crimper ndiyo yakanakisa sarudzo.Kune nhamba huru yemasampuli, otomatiki crimper inogona kushandiswa.
snap cap: Iyo snap chivharo ndeyekuwedzera kweiyo yekuisa chisimbiso ye crimp caps.Chivharo chepurasitiki pamucheto wezvivharo zvemuenzaniso zvinogadzira chisimbiso nekusvina septa pakati pegirazi uye chivharo chepurasitiki chakawedzerwa.Iko kunetseka muvharo yepurasitiki kunokonzerwa nekuedza kwayo kudzorera hukuru hwayo hwepakutanga.Iko kukakavara kunoumba chisimbiso pakati pegirazi, chivharo uye septa.Iyo yepurasitiki snap kavha inogona kuvharwa pasina chero zvishandiso.Kuvharika kwechisimbiso kwechifukidzo che snap hakuna kunaka sedzimwe nzira mbiri dzekuisa chisimbiso.· kana kupindirana kwevhavha kwakanyatso kusimba, chivharo chinonetsa kuvhara uye chinogona kutyoka. Kana iyo yakanyanyisa kusununguka, iyo yekuisa chisimbiso ichava yakaipa, uye septa inogona kusiya nzvimbo yayo yepakutanga.
Screw cap: Iyo screw cap ndeyepasi rose.Kusunga chivharo kunoshandisa simba remagetsi rinosvina septa pakati pegirazi rimu nekapu yealuminium.Mukati mekuita puncturing sampling, iyo yekuisa chisimbiso ye screw cap yakanakisa, uye gasket inotsigirwa nemichina nzira.Hapana maturusi anodiwa pakuungana.
Iyo PTFE / silicone septa ye screw cap yakagadzikwa pane polypropylene vials cap neisina solvent bonding process.Iyo tekinoroji yekubatanidza yakagadzirirwa kuve nechokwadi chekuti septa uye chivharo zvinogara zviri pamwe chete panguva yekufambisa uye kana chivharo chaiswa pamabhodhoro emuenzaniso.Uku kunamatira kunobatsira kudzivirira septa kubva pakudonha uye kushanduka panguva yekushandiswa, asi iyo huru yekuisa chisimbiso ichiri simba remakanika rinoshandiswa kana chivharo chadzvanywa pazvivharo zvemuenzaniso.
Iyo nzira ye cap tightening ndeyekugadzira chisimbiso uye kuchengetedza septa munzvimbo chaiyo panguva yekuiswa kweprobe.Izvo hazvifanirwe kupeta chivharo zvakanyanya, zvikasadaro zvinokanganisa kuiswa chisimbiso uye kuita kuti septa iwire pasi uye transpose.Kana iyo chivharo chakanyanya kuomeswa, septa ichaita kapu kana kubonoka.
03 Zvinhu zvemuenzaniso mabhodhoro
Type I, 33 mutsara-yekuwedzera borosilicate girazi:Ndiyo yakanyanya makemikari inert girazi parizvino.Inowanzo shandiswa mumarabhoritari ekuongorora kuti uwane mhinduro dzemhando yepamusoro dzekuyedza.Kuwedzera kwayo coefficient inenge 33x10 ^ (- 7) ℃, iyo inonyanya kuumbwa nesilicon oxygen, uye inewo trace boron uye sodium.Yese magirazi emvura mabhodhoro emhando I 33 mutsara-yekuwedzera girazi.
Type I, 50 mutsara-yekuwedzera girazi: Iyo yakawanda alkaline kupfuura 33 mutsara-yekuwedzera girazi uye inogona kushandiswa mumhando dzakasiyana dzema laboratory application.Kuwedzeredza kwayo kunenge 50x 10 ^ (- 7) ℃, iyo inonyanya kuumbwa nesilicon uye oksijeni, uye inewo shoma shoma yeboron.Mazhinji Hamag amber magirazi egirazi anogadzirwa kubva ku50 yekuwedzera girazi.
Type I, 70 mutsara-yekuwedzera girazi: Iyo ine hupfumi kupfuura 50 mutsara-yekuwedzera girazi uye inogona kushandiswa mumhando dzakasiyana dzekushandisa marabhoritari.Kuwedzeredza kwayo kunenge 70x 10 ^ (- 7) ℃, iyo inonyanya kuumbwa nesilicon uye oksijeni, uye inewo shoma shoma yeboron.Huru huwandu hweHamag mabhodhoro akajeka anogadzirwa kubva ku70 yekuwedzera girazi.
De activated glass (DV): Kune vanoongorora vane polarity yakasimba uye vanosunga kune polar girazi pamusoro pegirazi, kusashanda kweiyo sampuli vials inogona kuve sarudzo yakanaka.Hydrophobic girazi repamusoro rakagadzirwa nereactive silane kurapwa muchikamu chegirazi.Iyo yakavharwa sampuli vials inogona kuomeswa uye kuchengetwa nekusingaperi.
Polypropylene mapurasitiki: Polypropylene (PP) ipurasitiki isiri reactive inogona kushandiswa uko girazi risina kukodzera.Polypropylene sampuli mabhodhoro anogona kuramba akavharika zvakanaka kana apiswa, nokudaro achideredza mukana wekuratidzwa kune zvinogona kuva nengozi.Iyo yakanyanya tembiricha yekushanda i135 ℃.
