WD-2112B yog ib lub voj voog puv (190-850nm) ultra-micro spectrophotometer uas tsis tas yuav muaj lub khoos phis tawj ua haujlwm. Nws muaj peev xwm sai thiab raug kuaj xyuas nucleic acids, proteins, thiab cell daws. Tsis tas li ntawd, nws muaj hom cuvette rau kev ntsuas qhov concentration ntawm cov kab mob kab lis kev cai daws teeb meem thiab cov qauv zoo sib xws. Nws qhov rhiab heev yog xws li tias nws tuaj yeem ntes cov concentrations tsawg li 0.5 ng / µL (dsDNA).
