Chidule:
Ngakhale mbale zachitsanzo ndi zazing'ono, chidziwitso chambiri chimafunika kuti chigwiritse ntchito moyenera.Pakakhala mavuto ndi zotsatira zathu zoyeserera, nthawi zonse timaganiza za mbale zomaliza, koma ndi gawo loyamba loti tiganizire.Posankha mbale zoyenera zogwiritsira ntchito, muyenera kupanga zisankho zitatu: septa, chivindikiro, ndi mbale zomwezo.
01 Septa Selection Guide
PTFE: akulimbikitsidwa jakisoni imodzi, Kukana kwabwino kwa zosungunulira komanso kuyanjana kwamankhwala * palibe kusindikizanso pambuyo kuboola, Kusungidwa kwanthawi yayitali kwa zitsanzo sikuvomerezeka
PTFE / silikoni: akulimbikitsidwa jakisoni angapo ndi kusungira zitsanzo, Wabwinonso kusindikiza makhalidwe, Iwo ali kukana mankhwala a PTFE pamaso puncture, ndi ngakhale mankhwala silikoni pambuyo puncture, The ntchito kutentha osiyanasiyana - 40 ℃ mpaka 200 ℃
Pre-slit PTFE / silikoni:perekani mpweya wabwino kuti muteteze kupangika kwa vacuum mu mbale zachitsanzo, potero kukwaniritsa bwino sampuli reproducibility, Chotsani kutsekeka kwa singano pansi pambuyo sampuli, Kukwanitsa kusindikizanso bwino, Ndi bwino jekeseni angapo, Kutentha kwa ntchito ndi - 40 ℃ mpaka 200 ℃
(star slit )PE yopanda septa: Ili ndi zabwino zomwezo ngati PTFE
02 Zitsanzo Mbale kapu Guide
Pali mitundu itatu ya zipewa za Mbale: crimp cap, snap cap ndi screw cap.Njira iliyonse yosindikiza ili ndi ubwino wake.
zisoti za crimp: Chovala chotchinga chimafinya septa pakati pa m'mphepete mwa mbale zagalasi ndi kapu yopindika ya aluminiyamu.Kusindikiza kwake ndikwabwino kwambiri, komwe kungalepheretse kutulutsa kwachitsanzo.Malo a septum amakhalabe osasinthika pamene chitsanzocho chikuponyedwa kudzera mu jekeseni wodziwikiratu.Ndikofunikira kugwiritsa ntchito crimper kuti musindikize mbale zachitsanzo.Kwa zitsanzo zazing'ono, crimper yamanja ndiye chisankho chabwino kwambiri.Pazitsanzo zambiri, crimper yokha ingagwiritsidwe ntchito.
snap cap: Chophimba ndi chowonjezera cha njira yosindikizira ya zipewa za crimp.Chophimba chapulasitiki pamphepete mwa mbale zachitsanzo chimapanga chisindikizo mwa kufinya septa pakati pa galasi ndi kapu yapulasitiki yowonjezera.Kuthamanga kwa chivundikiro cha pulasitiki ndi chifukwa choyesa kubwezeretsa kukula kwake koyambirira.Kukangana kumapanga chisindikizo pakati pa galasi, kapu ndi septa.Chivundikiro cha pulasitiki chotchinga chikhoza kutsekedwa popanda zida zilizonse.Kusindikiza kwa chivundikiro chachitsulo sikuli bwino monga njira zina ziwiri zosindikizira.· Ngati kukwanira kwa kapu kuli kolimba kwambiri, kapu imakhala yovuta kutseka ndipo ikhoza kusweka. Ngati ili yotayirira kwambiri, kusindikiza kwake kudzakhala kosauka, ndipo septa ikhoza kusiya malo ake oyambirira.
Screw cap: Chophimbacho chimakhala chapadziko lonse lapansi.Kulimbitsa kapu kumakhala ndi mphamvu yamakina yomwe imafinya septa pakati pa mkombero wagalasi ndi kapu ya aluminiyamu.Pogwiritsa ntchito sampuli za puncturing, kusindikiza kwa screw cap ndikwabwino kwambiri, ndipo gasket imathandizidwa ndi njira zamakina.Palibe zida zomwe zimafunikira pakumanga.
Septa ya PTFE / silicone ya screw cap imakhazikika pa kapu ya polypropylene vials ndi njira yopanda zosungunulira.Ukadaulo womangirira wapangidwa kuti uwonetsetse kuti septa ndi kapu nthawi zonse zimakhala palimodzi panthawi yamayendedwe komanso kapu ikayikidwa pamiyendo yachitsanzo.Kumamatira kumeneku kumathandiza kuti septa isagwe ndi kusuntha pamene ikugwiritsidwa ntchito, koma njira yaikulu yosindikizira idakali mphamvu yamakina yomwe imagwiritsidwa ntchito pamene kapu ikugwedezeka pazitsulo zachitsanzo.
Makina omangira kapu ndi kupanga chisindikizo ndikusunga septa pamalo olondola pakuyika kwa kafukufukuyo.Sikoyenera kupukuta kapu mwamphamvu kwambiri, apo ayi zidzakhudza kusindikiza ndikupangitsa kuti septa igwe ndikutuluka.Ngati kapuyo yakulungidwa mwamphamvu kwambiri, septa imatha kapu kapena kupindika.
03 Zida za mbale zachitsanzo
Type I, 33 line-expension borosilicate glass: Ndilo galasi lopanda mankhwala kwambiri pakali pano.Nthawi zambiri amagwiritsidwa ntchito m'ma laboratories owunikira kuti apeze zotsatira zoyesera zapamwamba.Kukula kwake kumakhala pafupifupi 33x10 ^ (- 7) ℃, yomwe imapangidwa makamaka ndi silicon oxygen, komanso imakhala ndi trace boron ndi sodium.Mbale zonse zamagalasi amadzi ndi magalasi amtundu wa I33 wokulitsa mzere.
Type I, galasi lokulitsa mizere 50: Ndilo lamchere kwambiri kuposa galasi lokulitsa mizere 33 ndipo lingagwiritsidwe ntchito m'ma labotale osiyanasiyana.Kukula kwake kumakhala pafupifupi 50x 10 ^ (- 7) ℃, yomwe imapangidwa makamaka ndi silicon ndi mpweya, komanso imakhala ndi boron pang'ono.Magalasi ambiri a Hamag amber amapangidwa kuchokera ku galasi lokulitsa 50.
Lembani I, galasi lokulitsa mizere 70: Ndilo ndalama zambiri kuposa galasi lokulitsa mizere 50 ndipo lingagwiritsidwe ntchito m'ma labotale osiyanasiyana.Kukula kwake kumakhala pafupifupi 70x 10 ^ (- 7) ℃, yomwe imapangidwa makamaka ndi silicon ndi mpweya, komanso imakhala ndi boron pang'ono.Kuchuluka kwa mbale zomveka za Hamag zimapangidwa kuchokera ku galasi lokulitsa 70.
Magalasi otsekedwa (DV): Kwa ma analyte okhala ndi polarity amphamvu komanso omangika ku galasi la polar la galasi, kutseka kwa mbale zachitsanzo kungakhale chisankho chabwino.Magalasi a Hydrophobic adapangidwa ndi chithandizo cha silane chokhazikika mu gawo lagalasi.The deactivated chitsanzo Mbale akhoza zouma ndi kusungidwa mpaka kalekale.
Mapulasitiki a Polypropylene: Polypropylene (PP) ndi pulasitiki yosasunthika yomwe ingagwiritsidwe ntchito pomwe galasi siliyenera.Mbale zachitsanzo za polypropylene zimathabe kusindikizidwa bwino zikawotchedwa, motero kumachepetsa mwayi wopezeka ndi zinthu zomwe zingakhale zowopsa.Kutentha kwakukulu kwa ntchito ndi 135 ℃.
