Njira Yoyeretsa 1. Sambani ndi chisakanizo cha ether ndi mtheradi weniweni (50% iliyonse). 2. Ngati ili yodetsedwa kwambiri, gwiritsani ntchito mafuta odzolanu kuti muyeretse. Koma nthawi iyenera kukhala yochepa (mphindi 10), kenako muzimutsuka ndi madzi. Kusankhidwa kwa wothandizira kuyeretsa sagwiritsa ntchito zotchinga ngati sopo wa mbale. Kuti asakhudze muyeso. Chidziwitso: Onse otsogola atsogola amagwiritsa ntchito ma cuverart quartz, omwe amapangidwa ndi thupi la quartz, zomwe zimapangidwa ndi kutentha kwambiri pogwiritsa ntchito kutentha, zomwe zimachepetsa kuipitsidwa ndikumakhala ndi moyo wautali. (Mtengo wake ndi kawiri kuposa kawiri Pamwamba pazinthu zimapangidwa ndi manyazi, utoto wagalasi kumatentha kwambiri kuchimwa ndi guluu. Chifukwa chake samalani ndi mfundo zotsatirazi pogwiritsa ntchito :: 1. Mukamamwa cuvette, mutha kukhudza galasi la pansi mbali zonse ndi zala zanu, ndipo pewani kukhudza malo owoneka bwino. Nthawi yomweyo, samalani ndi chisamaliro kuti muchepetse mphamvu yakunja pazophweka ndi kuwonongeka pambuyo povuta. 2. Njira iliyonse yomwe ili ndi zinthu zomwe galasi la corrode suyenera kusungidwa mu cuvette kwa nthawi yayitali. 3. Osayika cuvette pa ntchentche kapena ng'anjo yamagetsi yotentha kapena kuphika m'bokosi louma; 4. 5. Osakhudza mawonekedwe a cuvette ndi zinthu zovuta kapena zonyansa. Mukamagwira yankho, kutalika kwake ndi 2/3 ya cuvette. Ngati pali madzi otsalira pa malo owoneka bwino, imatha kuthetsedwa pang'ono ndi pepala losefera, kenako ndikupukuta ndi mapepala kapena silika.
