1. Cov khoom siv tshuaj ntsuam: Vim li cas thiaj xaiv Borosilicate iav?
20ml scintillation vials feem ntau yog ua los ntawm hom kuv kawm ib qho iav borosilicate iav, conforming rau AstM E438 thiab USP cov qauv, muab cov txiaj ntsig hauv qab no:
- Tsawg cov keeb kwm yav dhau los: Tsawg-potassium iav tsim tawm txo cov kev cuam tshuam tom qab yav dhau los nyob rau hauv β-ray kuaj.
- Zoo tshuaj lom neeg inertness: Haum rau Organic cov kuab tshuaj xws li toluene thiab xylene.
- Lub Teeb Tshaj Tawm: Ua kom muaj txiaj ntsig kev sib kis ntawm scintillation teeb pom
2. Cov lus qhia tshwj xeeb: Qhov ntev thiab xov cov qauv
Txheem 20ml iav Scintillation feem ntau muaj cov qhov ntev thiab cov xov specificions:
- Txheej hauv lub taub: 28 hli
- Qhov siab: 57.5-61 hli
- Xov Qhia Tshwj Xeeb: 22-400 lossis 24-400
- Cov Khoom Siv Cap: Polypropylene (PP), urea resin, nrog cov hnab nqa khoom, nrog cov hnab nqa khoom nrog cov polyethylene cook Liners, PTFE zaj duab xis, thiab lwm yam.
3. Raug ntawv thov cov xwm txheej
20ml iav Scintillation vials tau siv dav hauv cov teb hauv qab no:
- Ua kua tshuaj scintillation suav: Rau kev tshawb nrhiav tsawg-zog β-rays xws li ³h thiab ¹⁴c.
- Kev Tshawb Xyuas Lub Chaw Haujlwm Saib Xyuas Ib puag ncig: Haum rau kev kuaj xyuas cov roj qis qis-nruab nrab hluav taws xob isotopes hauv dej thiab cov av kuaj.
- Kho Mob Piv Txwv Piv Txwv: Siv rau khaws cov qauv radiolabeled hauv kev tshawb fawb qog nqaij.
- Tshuaj Kev Tshawb Xyuas Kev Tshawb Fawb: Siv tau rau cov qauv ua hauv cov tshuab scquillation kua mis muaj cov kuab tshuaj organic.
4. Kev yuav lus pom zoo: Yuav ua li cas xaiv txoj kev scintillation vial?
Thaum mus yuav 20ml scintillation vials, xav txog cov hauv qab no yam:
- Kev tsim kho cov kev sim: Xaiv cov ntaub ntawv tsim nyog thiab cov kab ntawv cap uas tsim nyog raws li hom xov tooj cua tau raug kuaj pom.
- Sealing Performance: Xaiv cov kaus mom thiab cov hnab nrog cov khoom ntim tau zoo los tiv thaiv cov qauv evaporation lossis to.
- Kev sib haum: Xyuas kom cov Vial qhov ntev thiab cov xov specifications tau sib haum nrog cov khoom siv kuaj.
5. Cov lus nug nquag (FAQ)
Q1: Cov Vintination Vials yuav rov siv dua?
A1: Cov iav Scintillation tuaj yeem siv dua tshiab tom qab ua kom huv si thiab ua kom pom kev yooj yim, tab sis saib xyuas yuav tsum tau them rau kev ncaj ncees ntawm cap txoj kev sib khi ua haujlwm.
Q2: Yuav ua li cas xaiv lub cap thiab cov ntaub ntawv loj?
A2: Xaiv Cap thiab Liner cov ntaub ntawv raws li cov tshuaj lom neeg ntawm cov qauv; Piv txwv li, PTFE liners yog qhov tsim nyog rau cov qauv corrosive heev, thaum Polyethylene lub rooj tog kom haum rau General organic kuab tshuaj.
