Indlela yokucoca 1. Hlamba ngomxube we-ether kunye ne-ethanol epheleleyo (i-50% nganye). 2. Ukuba ingcolile kakhulu, sebenzisa i-lotion ekhethekileyo ukuyicoca. Kodwa ixesha kufuneka libe lifutshane (imizuzu eli-10), uze uhlambe ngamanzi. Ukukhetha isixhobo sokucoca Musa ukusebenzisa izicoci ezifana nesepha yezitya. Ukuze ungachaphazeli umlinganiselo. Qaphela: Zonke ii-spectrophotometers eziphambili zisebenzisa ii-quartz cuvettes ezinelungelo lobunikazi, ezenziwe ngezinto zomzimba ze-quartz ngokusebenzisa i-fusion bonding ephezulu yobushushu, enciphisa ungcoliseko kwaye inobomi obude benkonzo. (Ixabiso liphindwe kabini kunee-quartz cuvettes eziqhelekileyo) Qaphela I-cuvette ngokubanzi yi-rectangular parallelepiped, eneglasi egayiweyo ezantsi nasemacaleni omabini, kunye nomphezulu ocacileyo owenziwe ngeglasi ekhanyayo kwamanye amacala amabini. Umphezulu ocacileyo wenziwe nge-fusion, i-glass powder high temperature sintering kunye ne-glue bonding. Ngoko ke qaphela la manqaku alandelayo xa usebenzisa:: 1. Xa uthatha i-cuvette, ungachukumisa iglasi egayiweyo kumacala omabini ngeminwe yakho, kwaye uphephe ukuchukumisa umphezulu okhanyayo. Kwangaxeshanye, qaphela ukuphatha ngononophelo ukuthintela impembelelo yamandla angaphandle kwipleyiti yokwahlulahlula kunye nomonakalo emva koxinzelelo. 2. Nasiphi na isisombululo esinezinto ezigqwalisa iglasi akufuneki sigcinwe kwi-cuvette ixesha elide. 3. Musa ukubeka i-cuvette elangatyeni okanye kwisithando sombane ukuze sifudumale okanye sibhake kwibhokisi yokomisa; 4. Xa kufunyaniswe ukuba ingaphakathi le-cuvette lingcolisiwe, licoce nge-ethanol epheleleyo kwaye ulisule licoceke ngexesha elifanelekileyo. 5. Musa ukuchukumisa umphezulu ocacileyo we-cuvette ngezinto eziqinileyo okanye ezingcolileyo. Xa ubambe isisombululo, ukuphakama yi-2/3 ye-cuvette. Ukuba kukho ulwelo oluseleyo kumphezulu obonakalayo, lunokufunxwa kancinci ngephepha lokucoca, uze usule ngephepha lelensi okanye isilika.
