Nucleic Acid Concentration Analyzer

The Nucleic Acid Concentration Analyzer (Ultramicro Spectrophotometer) is a spectroscopic analyzer specifically designed for modern life science laboratories. Based on UV-visible spectrophotometry, it employs micro-column surface tension detection and automatic three-pathlength switching technology to achieve precise quantitative analysis of nucleic acid and protein samples, offering high sensitivity, a wide dynamic range, excellent stability, and rapid testing. Featuring a color touchscreen interface, the instrument supports cloud-based remote updates and detection data management, making it an ideal tool for analyzing microvolumes of samples in fields such as molecular biology, clinical testing, and research and education.

The core detection principle of this instrument is UV-visible spectrophotometry. Based on the characteristic selective absorption of specific wavelengths of UV or visible light by analytes (such as nucleic acids and proteins) in a sample, the absorbance is directly proportional to the concentration of the substance, following the Lambert-Beer law. By measuring the absorbance of the sample at characteristic wavelengths, quantitative analysis of the sample’s composition is achieved.

The applicable standard is JJF 1836-2020, “Calibration Specification for Microvolumetric Spectrophotometers.”

Applications include the following areas:
Life Sciences and Medical Research: Provides fundamental testing support for nucleic acid concentration measurement, protein quantification, and microbial growth monitoring in university, research institute, and hospital laboratories.
Pharmaceuticals and Biotechnology: Supports the entire drug R&D process, including candidate compound screening, pharmacodynamic and toxicological evaluations, and quality control of biopharmaceuticals.
Expanded Applications Across Multiple Industries: Can be applied in food safety, agriculture, and environmental monitoring, providing testing tools for quality control and safety screening across various industries.
