I-WD-2112B iyi-wavelength egcwele (190-850nm) i-ultra-micro spectrophotometer engadingi ikhompuyutha ukuthi isebenze. Iyakwazi ukubona ngokushesha nangokunembile ama-nucleic acid, amaprotheni, nezixazululo zamangqamuzana. Ukwengeza, ifaka imodi ye-cuvette yokulinganisa ukugxila kwezixazululo zesiko lebhaktheriya namasampuli afanayo. Ukuzwela kwayo kufana nokuthi ikwazi ukubona ukugxila okuphansi njengo-0.5 ng/µL (dsDNA).
