MN-917 | MaestroNano micro-volume spectrophotometer for DNA, RNA and protein quantification

Key Features

  • Advanced instrumentation for the precise measurement of nucleic acids and purified proteins
  • Large concentration range from 2 ng - 2000 ng/µL dsDNA so no sample dilution required
  • Only 2 µL of sample required to quantify DNA, RNA or protein concentration
  • Single fixed path length (0.5 mm) significantly reduces frequency of recalibration
  • Auto-calibration at turn on with one step recalibration
  • Direct measurement in less than 5 seconds with normalization of concentration
  • Four measurement wavelengths available: 230 nm, 260 nm, 280 nm and 320 nm
  • Xenon flash lamp light source with automatically adjustable light intensity provides more stable long-term performance
  • No cuvettes or capillaries needed so no consumable costs. No requirement for calibration solutions.
  • Embedded Android operating system so no external PC needed
  • Includes integrated thermal printer and built-in touch screen with intuitive interface


The MaestroNano micro-volume spectrophotometer from Maestrogen has been specifically designed for the analysis of samples as small as 2 µL. The unit features a novel optical system design that allows the measurement of extremely low concentrations of proteins and nucleic acids including double-stranded DNA (dsDNA), single stranded DNA (ssDNA) and ribonucleic acid (RNA). Samples are pipetted directly onto the optical measurement point so no cuvettes or capillaries are required.

The MaestroNano features an embedded computer running an Android operating system. It also includes a built-in thermal printer and LCD touch screen and all commands are entered through an intuitive interface. The measurement system uses a single fixed path length (0.5 mm) which significantly reduces the frequency of recalibration. 

Four measurement wavelengths are available: 230 nm, 260 nm, 280 nm and 320 nm. Measurements can be made as follows:

  • OD230 nm, OD260 nm, OD280 nm, OD320 nm
  • Sample concentration (ng/µL)
  • OD260 nm/ OD230 nm | OD 260 nm/ OD280 nm

More Information

The MN-917 is supplied with a set of reusable quartz glass optical plates (MN-917-OP) and three rolls of thermal paper (MN-917-TP) for the embedded printer.
