MN-917 DNA RNA Protein Spectrophotometer

MN-917 MaestroNano

DNA RNA Protein Quantification Spectrophotometer


MaestroNano is a spectrophotometer for bio-chemical research only. The main function is micro volume concentration quantification, for nucleic acid including double-stranded nucleic acid (dsDNA), single-stranded nucleic acid (ssDNA), and ribonucleic acid (RNA), or protein solution.

To satisfy most users’ 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 to achieve more accurate measurement results.

After dispensing sample on the surface of the central area of the quartz glass, users can select sample type and begin to measure.

Reliable, repeatable, and reproducible concentration
MaestroNano does not intend to change light path-length during measurement to reduce frequency of calibration. Instead, MaestroNano develops and offers an in-house mathematical algorithm to help users acquire more reliable, repeatable, and reproducible bio-chemical solution concentrations.

Non-optical-fiber design
With MaestroGen’s new technology, non-optical-design, MaestroNano can offer the high reliability in accuracy and prevent from the unavoidable issue caused by the attenuation of light intensity in the optical path when the device equipped with fiber-optic components as consumables. 

High precision in the positioning of optical path
The height of optical path-length is precisely fixed in 0.5mm by fixed pin. Compared to other micro volume spectrophotometers, which need to be constantly calibrated to maintain the precision and to make the optical path length into position, MaestroNano works with a metal cover that can “straightly” go up and down in y-axial via a reliable slider and that way contributes to the rigid positioning of the optical path length in y-axis and always to be perpendicular to the bottom quartz glass.

Accessible measurement results
The measurement results can be accessible via the embedded touch panel, thermal printer, USB storage as well as Wi-Fi transfer.

Adjustable light intensity contributes to the stable performance
In order to prevent from the impacts caused by the derivations in various environmental conditions, such as different ranges of temperature, humidity, latitude, etc., and to make sure the measurement for the same sample should be leaded to the same results, the adjustable light source provides with the adjustable voltage in intensity. With this new technology, user just needs two micro-liter of ddH2O as the standard volume, and gets back to the stable performance again via the built-in calibration mode.

Compared to other spectrophotometers
There are some kinds of micro volume spectrophotometer for DNA, RNA and protein right now. But MaestroNano is definitely the most special one. Most spectrophotometers use whole wavelength spectrum from 200nm to 900nm, need calibration by experts time to time, and install software in another stand-alone computer to operate. MaestroNano provides a much better and more economical solution for most functions. By using the specific useful wavelengths (230/260/280/320nm) and automatic calibration, the embedding operating system offers an outstanding performance of accuracy and a much lower price compared to other spectrophotometers. Also, MaestroNano is a “non-optical-fiber” system, which can contribute to the longer product life-time compared to others embedded with optical fiber as consumables.
