Micro-volume Spectrophotometer

micro volume spectrophotometer




About Micro Volume Spectrophotometer , ProNano micro-volume spectrophotometer

is designed for Protein measurement , it is a quick and accurate quantification

of protein analysis. 

Focusing on BCA, Bradford and Pierce 660 assay, ProNano has light source

with three wavelengths for most of the quantification requirements of protein.

Unlike traditional methods, ProNano needs less sample size, less reacting time, and provides the same performance.

Just need only 2ul samples are needed to be measured, and only 10 minutes reacting time is required, which is much less than traditional

30 mins to 2 hours. 

The linearity reaches R square > 0.99 for every assay, and reproducibility is stable.

As like MaestroNano Pro spectrophotometer, ProNano doesn't need any calibration and can be operated by embedded system.

Also for the storage data that can be accessed by USB port to PC.
