Ib qho chaw sib cais, tsis hais txog ntawm nws cov khoom siv, yog qhov tseem ceeb ntawm lub raj mis nrog lub caj dab nqaim thiab lub stopcock.(valve) ntawm nws lub hauv paus. Nws lub hom phiaj tseem ceeb yog los pab txhawb kev sib cais ntawm ob qho tib si immiscible (tsis yog sib xyaw)kua.
Feem ntau, ib qho kua yog denser dua lwm qhov, tso cai rau lub ntiajteb txawj nqus cais lawv mus rau hauv cov txheej txheem sib txawv hauv qhov funnel. Thaum kev sib cais tiav lawm, cov kua denser tuaj yeem maj mam tso tawm los ntawmstopcock ntawm lub hauv paus, tawm hauv cov kua sib dua qab.
Yas cais funnels txawv ntawm iav qauv feem ntau nyob rau hauv lawv cov khoom muaj pes tsawg leeg. Tsim los ntawm cov khoom siv ruaj khov, high-density polyethylene (HDPE) lossis lwm yam yas zoo sib xws, cov funnels no muaj kev ua haujlwm zoo.
tiv thaiv kev tawg thiab tawg, uas yog ib qho kev txhawj xeeb tseem ceeb nrog iav. Ntxiv mus, cov qauv yas feem ntau tsim nrog cov yam ntxwv ntxiv los txhim kho cov neeg siv kev nyab xeeb thiab yooj yim. |
Tsim Nta ntawm Yas Separatory Funnels
Khoom siv
Kev xaiv cov khoom siv yas yog qhov tseem ceeb hauv kev tsim cov funnels cais. HDPE yog qhov kev xaiv nrov vim nws cov tshuaj tiv thaiv zoo heev, ua haujlwm ntev, thiab lub teeb yuag. Cov khoom siv no tuaj yeem tiv taus ntau yam kub thiab tshuaj lom neeg, ua rau nws haum rau ntau yam kev siv hauv chav kuaj. Lwm yam
yas, xws li polypropylene los yog polyvinyl chloride (PVC), kuj yuav siv tau nyob ntawm tej yam yuav tsum tau, xws li kub kam rau siab los yog cov nqi txiav txim siab.
Stopcock Design
Lub stopcock, los yog valve, ntawm lub hauv paus ntawm lub funnel yog ib qho tseem ceeb tivthaiv. Nws yuav tsum yog tsim los muab cov foob kaw kom tiv thaiv kom tsis txhob to feakage thaum tso cai rau kev tswj cov kua. Yas cais funnels feem ntau feature PTFE (polytetrafluoroethylene)-lined stopcocks, uas muaj superior tshuaj
compatibility thiab sealing kev ua tau zoo. Cov stopcocks no kuj tsim los ua kom yooj yim rau kev khiav lag luam, txawm tias thaum hnav hnab looj tes, ua kom cov neeg siv yooj yim thiab nyab xeeb.
Muaj peev xwm thiab kawm tiav
Separatory funnels tuaj nyob rau hauv ntau qhov ntau thiab tsawg, feem ntau yog li ntawm 50 mL mus rau ob peb litres. Lub peev xwm xaiv yog nyob ntawm qhov ntim ntawm cov kua uas tau muab cais thiab cov kev xav tau tshwj xeeb ntawm qhov kev sim.
Tsis tas li ntawd, yas cais funnels feem ntau kawm tiav, txhais tau hais tias lawv muaj cov cim nyob rau hauv lawv sab qhia txog qib ntim. Cov yam ntxwv no yog qhov tseem ceeb rau kev ntsuas kom raug thiab saib xyuas cov kua ntim thaum lub sijhawm sib cais.
Ergonomic Tsim
Niaj hnub nimno yas cais funnels suav nrog ergonomic tsim qauv los txhim kho cov neeg siv kev nplij siab thiab txo qhov kev pheej hmoo ntawm kev raug mob. Qhov no suav nrog cov yam ntxwv xws li lub qhov ncauj dav kom yooj yim nchuav thiab ntxuav,
textured grips rau kev tuav zoo dua, thiab cov duab contoured kom txo qis thaum siv.
Functional Advantages ntawm Yas Separatory Funnels

Durability thiab Kev nyab xeeb Ib qho tseem ceeb tshaj plaws ntawm cov yas cais funnels yog lawv cov kav ntev. Tsis zoo li iav, yas tsis tawg lossis tawg yooj yim, txo qhov kev pheej hmoo ntawm kev raug mob thiab raug mob hauv chav kuaj. Qhov no ua rau cov yas funnels tshwj xeeb tshaj yog haum rau ib puag ncig uas tuav ntxhib los yog poob qis dua. Tsis tas li ntawd, cov yas tsis kam ua kom tawg tshem tawm qhov kev pheej hmoo ntawm cov tawg tawg, uas tuaj yeem ua rau muaj kev phom sij loj heev hauv chav kuaj. Cov khoom siv tshuaj sib xyaw ua ke kuj ua kom ntseeg tau tias nws tsis cuam tshuam nrog cov kua dej sib cais, ntxiv dag zog rau kev nyab xeeb.
Lub teeb thiab Yooj yim rau tuav Yas cais funnels yog lub teeb yuag piv rau cov qauv iav, ua rau lawv yooj yim rau kev tswj thiab tswj. Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig thaum lub sij hawm ntev los yog rov ua dua qhov kev sim, qhov twg qhov hnyav txo tuaj yeem txo cov neeg siv qaug zog thiab txhim kho kev ua haujlwm tag nrho. |
