Domestic ultra micro spectrophotometer

Domestic ultra micro spectrophotometers usually refer to a very small concentration range of substances, between nanoKelvin and picoKelvin. Specifically, trace amounts refer to chemical substances or elements with concentrations ranging from 1 to 100 picomoles per liter (pg/mL).

　　Functions of domestic ultra micro spectrophotometer:

UV detection: detect the absorbance value of the sample at conventional UV wavelengths;

Nucleic acid testing: It can detect the concentration of different types of nucleic acids such as dsDNA, ssDNA, RNA, and their absorbance values at 260nm and 280nm;

Probe detection: detecting the absorbance value of fluorescently labeled probes, which can be used to remove samples that have not been labeled with probes;

Protein detection: detect the concentration of purified protein and the absorbance at 280nm, and perform quantitative analysis of BCA, Bradford, Lowry, Pierce 660nm proteins;

Bacterial solution/suspended cell concentration detection: can detect the OD600 value of bacterial solution and monitor the growth of suspended cells;

Dynamics detection: used for measuring enzyme activity and growth curves in kinetic experiments;

Full wavelength scanning: 185-910nm full wavelength scanning, displaying absorption curve;

User defined detection: The detection parameters can be customized, such as large absorption peak, calculation formula, etc.
