Nzira yekuchenesa 1. Geza nemusanganiswa we ether ne absolute ethanol (50% imwe neimwe). 2. Kana yakasviba zvakanyanya, shandisa lotion yakakosha kuti uichenese. Asi nguva inofanira kuva pfupi (maminitsi gumi), wozogeza nemvura. Sarudzo yemushonga wekuchenesa. Usashandise sipo dzakadai sesipo yedhishi. Kuti usakanganise chiyero. Cherechedza: Ma spectrophotometer ese epamusoro anoshandisa ma quartz cuvettes ane patent, ayo akagadzirwa nezvinhu zve quartz body material kuburikidza ne high temperature fusion bonding, izvo zvinoderedza kusvibiswa uye zvine hupenyu hwakareba. (Mutengo wacho wakapetwa kaviri pane we quartz cuvettes dzakajairika) Cherechedza dhizaini iyi inowanzova rectangular parallelepiped, ine ground glass pasi nemativi ese, uye transparent surface yakagadzirwa ne optical glass kune mamwe mativi maviri. Transparent surface yakagadzirwa ne fusion, glass powder high temperature sintering uye glue bonding. Saka teerera pane zvinotevera paunenge uchishandisa:: 1. Paunotora cuvette, unogona kungobata ground glass kumativi ese neminwe yako, uye usabata optical surface. Panguva imwe chete, nyatsoteerera kubata kwacho kudzivirira simba rekunze paplate yekuenzanisa uye kukuvara mushure mekumanikidzwa. 2. Chero mhinduro ine zvinhu zvinoparadza girazi haifanirwe kuchengetwa mucuvette kwenguva yakareba. 3. Usaise cuvette pamoto kana muchoto chemagetsi kuti upise kana kubheka mubhokisi rekuomesa; 4. Kana zvikaonekwa kuti mukati mecuvette makasviba, chenesa neethanol chaiyo woipukuta nepanguva. 5. Usabata pamusoro pecuvette nezvinhu zvakaoma kana zvakasviba. Paunenge wakabata mhinduro, kureba kwayo i2/3 yecuvette. Kana paine mvura yasara pamusoro peoptical, inogona kunyudzwa zvishoma ne filter paper, uye yozopukutwa ne lens paper kana silk.
