Iifenili

1. inkcazo:

IifenilizisetyenziselwaUkuhluza kunye nokwahlukana.

1.Songa iphepha lesihluzo phakathi uze ulisonge kabini ukuze wenze i-engile esembindini ye-90 °.

2. Beka iphepha lesihluzo elihlanganisiweyo libe ziileya ezintathu kwelinye icala uze uvule elinye icala ukuze wenze i-funnel.

3. Faka iphepha lesihluzo elimile okwe-faneli kwi-funnel. Icala lephepha lesihluzo kufuneka libe ngaphantsi kunecala le-funnel. Galela amanzi emlonyeni we-funnel ukuze iphepha lesihluzo elimanzi lijikeleze udonga olungaphakathi lwe-funnel, uze ugalele amanzi acocekileyo aseleyo ukuze uwasebenzise.

4.Beka i-funnel kunye nephepha lesihluzo kwisibambi se-funnel ukuze ucoce (njengeringi ekwi-iron stand), kwaye ubeke i-beaker okanye ityhubhu yokuvavanya equlethe ulwelo lwesihluzo phantsi kwentamo ye-funnel, kwaye ubeke incam yentamo ye-funnel eludongeni lwesikhongozeli sokwamkela. Thintela ukutshiza kolwelo.

5. Xa ufaka ulwelo oluza kuhluzwa kwi-funnel, bamba i-beaker ebambe ulwelo ngasekunene kunye ne-glass rod ngasekhohlo. Isiphelo esisezantsi se-glass rod sikufutshane neengqimba ezintathu zephepha lesihluzo. I-beaker cup ikufutshane ne-glass rod. I-rod ingena kwi-funnel. Qaphela ukuba inqanaba lolwelo olungena kwi-funnel alinakudlula ukuphakama kwephepha lesihluzo.

6. Xa ulwelo luhamba ngentamo ye-funnel ngephepha lesihluzo, jonga ukuba ulwelo luhamba ngodonga lwekomityi uze uluthululele ezantsi kwekomityi. Ukuba akunjalo, susa i-beaker okanye ujikelezise i-funnel ukuze incam ye-funnel inamathele ngokuqinileyo eludongeni lwe-beaker, ukuze ulwelo luhambe ngodonga lwe-beaker.

2. Umzobo oQhelekileyo

3.Izinto ezisetyenziswayo: PP

4. Inkcazelo:50mm(SMD-FUNS),120mm(SMD-FUNM),150mm(SMD-FUNL)
