MaestronanoMaestroNano -
Micro-Volume Spectrophotometer


  • Simplicity of use – just pipette and wipe
  • Direct, easy measurements in less than 3 seconds.
  • Only 2 μL volumes needed to quantify DNA, RNA and proteins concentration.
  • Large concentration range (2 ng/µL – 2,000 ng/µL dsDNA) without dilutions.
  • Measures DNA, RNA (A260) and Protein (A280) concentrations and sample purity (A260/A280 ratio)

Simplicity of use – just pipette and wipMaestroNano, a micro-volume spectrophotometer suitable for research use . The main function of MaestroNano is the concentration measurement from two micro liter nucleic acid or protein solution. Nucleic acid means double-stranded nucleic acid (dsDNA), single-stranded nucleic acid (ssDNA), and ribonucleic acid (RNA). MaestroNano has an embedded system, and there are ONLY three buttons as user interface. After dispensing sample on the surface of fiber terminals, users may use the buttons to select sample type and begin to measure. The measurement results can be obtained from liquid crystal display (LCD), and thermal printer.

MaestroNano is a specialized instrument for bio-chemical research only, especially for micro-volume solution concentration measurement. It is designed by Maestrogen and realizes a user-friendly interface, accurate measurement, competitive price, and stylish industrial design.

To satisfy most people’s requirements for concentration measurement, MaestroNano defines a most reliable measurement range of concentration of 2~2000 ng/μL, and successfully resists the interferences of ambient light for a more accurate measurement. Also, MaestroNano does not intend to change light pathlength during measurement to reduce frequency of calibration. Instead, MaestroNano develops and offers an in-house mathematical algorithm to help users acquire a more reliable, repeatable, and reproducible bio-chemical solution concentrations.
