Ultra-micro ultraviolet-visible spectrophotometer is a full-wavelength ultra-micro ultraviolet-visible spectrophotometer, the micro detection mode can be used to detect nucleic acids, micro nucleic acid arrays, pure protein detection, labeled protein detection, protein quantitative detection, microbial cell culture detection and regular full-wavelength scanning. In the cuvette detection mode, nucleic acids, proteins, and microbial cells can be measured Cultivation and kinetic testing. The fluorescence detection module can perform fluorescence quantification of nucleic acid. After the fluorescent dye is combined with a specific target molecule, the fluorescence intensity is detected to measure the concentration of the target molecule. It is used to detect low-concentration samples with high accuracy. Fluorescence detection is suitable for the detection of trace amounts of samples, usually ultra-low concentration samples that cannot be measured by photometers.
