Njira yoyeretsera 1. Tsukani ndi chisakanizo cha ether ndi absolute ethanol (50% iliyonse). 2. Ngati ndi yodetsedwa kwambiri, gwiritsani ntchito lotion yapadera kuti muyeretse. Koma nthawi iyenera kukhala yochepa (mphindi 10), kenako muzimutsuka ndi madzi. Kusankha chotsukira Musagwiritse ntchito sopo monga sopo wothira mbale. Kuti musakhudze muyeso. Dziwani: Ma spectrophotometer onse apamwamba amagwiritsa ntchito ma quartz cuvettes opangidwa ndi patent, omwe amapangidwa ndi zinthu za quartz kudzera mu high temperature fusion bonding, zomwe zimachepetsa kuipitsa ndipo zimakhala ndi moyo wautali. (Mtengo wake ndi wowirikiza kawiri kuposa ma quartz cuvettes wamba) Dziwani kusintha kwa cuvette nthawi zambiri imakhala ndi rectangular parallelepipe, yokhala ndi galasi lophwanyika pansi ndi mbali zonse ziwiri, ndipo pamwamba pake pali galasi lowonekera mbali zina ziwiri. Pamwamba pake pali fusion, ufa wagalasi wotentha kwambiri komanso guluu wolumikizana. Chifukwa chake samalani mfundo zotsatirazi mukamagwiritsa ntchito:: 1. Mukatenga cuvette, mutha kungokhudza galasi lophwanyika mbali zonse ziwiri ndi zala zanu, ndipo pewani kukhudza pamwamba pake. Nthawi yomweyo, samalani ndi chogwirira mosamala kuti mupewe mphamvu yakunja pa mbale yosiyanitsa ndi kuwonongeka pambuyo pa kupsinjika. 2. Yankho lililonse lokhala ndi zinthu zomwe zimawononga galasi siliyenera kusungidwa mu cuvette kwa nthawi yayitali. 3. Musayike cuvette pa moto kapena ng'anjo yamagetsi kuti mutenthetse kapena kuphika mu bokosi lowumitsira; 4. Mukapezeka kuti mkati mwa cuvette mwaipitsidwa, yeretsani ndi ethanol yeniyeni ndikupukuta bwino nthawi yake. 5. Musakhudze pamwamba powonekera pa cuvette ndi zinthu zolimba kapena zodetsedwa. Mukagwira yankho, kutalika kwake ndi 2/3 ya cuvette. Ngati pali madzi otsala pamwamba pa kuwala, amatha kuyamwa pang'ono ndi pepala losefera, kenako nkupukuta ndi pepala la lens kapena silika.
